1. Introduction
Version followed: community food growing as UK and US bodies publish it: the cross-government Green Social Prescribing Toolkit (National Academy for Social Prescribing, 2026 revised edition), NHS England's green social prescribing page, the National Allotment Society (NAS), the American Community Gardening Association (ACGA), Incredible Edible Todmorden as The Ecologist reported it (2014), and social and therapeutic horticulture (STH) as Thrive describes it through the National Academy for Social Prescribing (NASP). Social Farms & Gardens (the UK charity for community gardens, city farms and care farms) is the lead UK body for the sector [uncertain: not verified]; its own practice guidance is not summarised here.
Community gardening, allotments and food-growing projects are not a psychotherapy. They are community and civic activities: a council-let allotment plot worked by a tenant, a shared community garden run by staff or volunteers, school and hospital gardens, and open public growing of the Incredible Edible kind. ACGA describes the range as running from family allotments and pocket parks to school gardens and urban farms, and its aim as building community through gardening and greening [source: ACGA About]. In England these settings are among the named destinations of green social prescribing, in which GPs, other practitioners and local agencies refer people to a link worker, who connects them to nature-based activities such as community gardening and food growing [source: NHS England green social prescribing]. STH is the more structured end: trained practitioners use gardening to improve physical and mental wellbeing, communication and social skills [source: NASP, Thrive case study].
The psychotherapist's job is usually not to run the garden. It is to judge fit and readiness, refer or signpost (often through a link worker), prepare the client for a first visit, liaise with garden staff with consent, use what happens on the plot in therapy (activity, mastery, belonging, patience with slow growth, loss), and keep the client safe around food, soil, weather and tools. Some therapists also deliver garden-based sessions themselves; that is a dual role with its own training and insurance demands (see 4.14).
How change is thought to happen, as the bodies state it: gardening offers gentle, accessible activity, time in nature that reduces stress, and a social setting in which people communicate and reconnect [source: NASP, Thrive case study]; allotment social contact helps reduce loneliness [source: NAS Media Information 2025]; Incredible Edible's founders frame shared, visible growing as a way to build self-esteem, skills and community ("If you eat, you're in") [source: The Ecologist 2014]. These are the organisations' accounts. Evidence status in one line: a systematic review concluded that allotment gardening does impact health and wellbeing, while noting most research concerns group and therapeutic gardening [source: Genter et al. 2015]; a Tokyo survey found allotment gardeners reported better health and social cohesion than non-gardeners (association, not causation) [source: Soga et al. 2017]; the national green social prescribing test-and-learn programme reported statistically significant pre-post gains on ONS4 wellbeing questions, with no control group described [source: NASP 2024 evaluation news].

2. Framework
There is no manualised phase structure. The bodies describe a referral-and-participation pathway, which this guide organises into five phases [synthesis, built on the NASP toolkit pathway]. No source gives a session count or programme length for community gardening; allotment tenancies are open-ended and council waiting lists can be long (a 2023 APSE study reported by NAS found most councils had average waits of over 18 months) [source: NAS Media Information 2025].
Phase A. Exploration and assessment (in therapy). Goal: a "what matters to you" conversation that leads to a simple personalised plan [source: NASP toolkit]; screening for physical, sensory, allergy, mobility, eating and risk issues [synthesis]. Move on when the client wants to try growing, the purpose is named (company, routine, mastery, food, being outdoors) and no acute risk is present. Green social prescribing is not a route for acute mental illness [source: NASP toolkit].
Phase B. Matching and referral. Goal: choose the setting that fits need and capacity: own or shared allotment plot (independent, waiting list, tenancy rules set by the council or association) [source: NAS]; staffed community garden or food-growing project; STH with trained practitioners for higher support needs [source: NASP, Thrive]. Referral can run through a link worker, or by self-referral [source: NASP, Thrive]. Move on when a provider has accepted the referral and its criteria fit (some areas use mental-health "levels" or cohort criteria so providers are not asked to hold people in crisis) [source: NASP toolkit].
Phase C. Preparation and first attendance. Goal: reduce anxiety about starting through a warm handover: clinician introduction, a one-to-one chat with the provider, a site visit before joining; pre-meets, taster sessions, "nature buddy" volunteers and walkthrough videos [source: NASP toolkit]. Move on after the first attendance has happened and been debriefed.
Phase D. Participation with therapy alongside. Goal: regular involvement, with therapy using the garden material (activity, relationships, setbacks, meaning). Review using whatever measures fit; the toolkit notes ONS4 was used by some sites and found triggering by some participants, others used the Outcomes Star or co-designed measures [source: NASP toolkit]. Move on when participation is self-sustaining or the plan needs changing.
Phase E. Step-down and ending. Goal: clear routes from structured programmes to community nature groups or an own plot, so gains last [source: NASP toolkit]; ending or spacing therapy with the garden as a continuing support [synthesis].
Format: individual therapy sessions in the usual setting, with the garden as an outside activity; or, where the therapist is trained and insured, sessions held in a garden (4.14). Group size, frequency and length are set by each project, not by any source here.
3. Guiding principles
- Start from what matters to the client. The plan follows their stated aims, not a prescription of "nature" [source: NASP toolkit].
- It is a community activity, not treatment. Gardens do not provide clinical care; keep therapy, risk management and crisis planning with the clinical team [source: NASP toolkit].
- Match support to need. Volunteer-run gardens may be too stretched for high-need referrals; staffed or STH settings suit higher needs [source: Sustain 2019; NASP toolkit].
- Warm handover beats a leaflet. Introductions and visits reduce drop-out at the door [source: NASP toolkit].
- Consent governs every piece of information shared. Share the minimum the provider needs to judge fit and keep the person safe [synthesis; providers' need for history and needs: source: NASP toolkit].
- Respect the provider's limits. Garden leaders want clarity on responsibilities, safeguarding, health and safety and duty of care [source: Sustain 2019].
- Accessibility is designed in. Transport, footpaths, toilets, plain language, timing, single-gender options and childcare all matter [source: NASP toolkit]; raised beds and sensory gardens exist on some sites [source: NAS].
- Activity, not exercise prescription. Gardening is gentle activity; never set durations, intensities or frequencies; route physical questions to the client's physician or a qualified exercise professional and frame participation as behavioural activation (II 040) [synthesis].
- Food without diet advice. Growing and sharing food is welcome material; no diet plans, weight, calorie or macronutrient targets, fasting or supplement advice; screen for disordered eating and refer to a registered dietitian or eating-disorder service [synthesis].
- Safety is qualitative and routed. Soil contamination, tools, weather, sun, stings, ticks and allergies are handled through the site's own rules and public-health guidance [source: SF Department of Public Health 2017 for soil lead; otherwise synthesis].
- Seasons set the pace. Growth is slow and failures are common; use this as material rather than a measure of the client [synthesis].
- The client authors the meaning. Metaphors of growth, roots or harvest are offered, not imposed [synthesis].
- Stay in role. If you also run or volunteer at a garden, manage multiple relationships under APA Ethics Code Standard 3.05 (APA Ethics Code); competence and insurance must fit what you deliver [synthesis].
- Measure lightly. Choose measures that are practical, free and acceptable; paper forms can undermine the experience [source: NASP toolkit].
4. Intervention inventory
The published sources describe a referral pathway and the activities, not therapist techniques. The procedures below are therapist-side; those not described by a source are marked [synthesis]. Example language is illustrative throughout.
4.1 "What matters to you" exploration
- Purpose / when: Phase A, whenever a client mentions gardens, food, wanting to get out, loneliness or lack of routine. Establishes what growing would be for [source: NASP toolkit for the conversation; therapy use: synthesis].
- Steps: (1) Ask what a good week would contain. (2) Ask about past contact with growing (family plots, rural childhood, heritage crops, school gardens). (3) Name the hoped-for gains in the client's words: company, structure, skill, being outdoors, food, quiet. (4) Ask what would make it hard (energy, pain, social anxiety, money, transport, caring duties). (5) Write a one-line plan with the client.
- Example language (illustrative): "If you were down at a garden on a good day, what would you be doing, and who would be there?"
- Watch for: the idea coming from you rather than the client; a plan that is really about weight or food control (see 4.12); hopes the setting cannot meet. Working: the client adds detail and questions of their own.
4.2 Health, safety and access screen
- Purpose / when: Phase A, before any referral. Identifies needs the provider must know and risks to route elsewhere [synthesis].
- Steps: (1) Ask about mobility, pain, balance, sensory loss, fatigue. (2) Ask about allergies (pollen, plants, insect stings, latex in gloves) and any history of severe reactions. (3) Ask whether any health condition or medicine makes heat, sun or exertion a concern, and route that question to their physician or pharmacist; never advise on medicines. (4) Ask about current risk, crisis plans and substance use. (5) Ask about eating and food concerns (4.12). (6) Note access needs: toilets, paths, transport, language, childcare [source for access items: NASP toolkit].
- Example language (illustrative): "Gardens can mean pollen, wasps, bending and kneeling. Is there anything in your health I should know so we pick somewhere that works for your body?"
- Watch for: unexplained breathlessness or chest symptoms with exertion, recent falls, or severe allergy without a plan: refer to the GP or physician before starting. Working: a short list of needs the client is happy to share.
4.3 Matching the setting
- Purpose / when: Phase B. Chooses between an allotment plot, a community garden, an open food-growing project, or STH.
- Steps: (1) Independent, confident clients with steady energy: allotment plot or a shared or half plot; note waiting lists and tenancy rules (council or association) [source: NAS]. (2) Clients who want company and structure: staffed community garden or food-growing group. (3) Higher support needs (learning disability, stroke, severe mental ill-health, sensory loss): STH with trained practitioners [source: NASP, Thrive]. (4) Clients drawn to civic action and public visibility: open growing of the Incredible Edible kind [source: The Ecologist 2014]. (5) Check the provider's referral criteria and whether it accepts people at the client's level of need [source: NASP toolkit].
- Example language (illustrative): "Some places are your own patch and you come and go; others are a group with a leader and a tea break. Which sounds more like you right now?"
- Watch for: sending high-need clients to stretched volunteer-run gardens [source: Sustain 2019]. Working: the client chooses with reasons.
4.4 Vetting a provider
- Purpose / when: Phase B, before referring to an unfamiliar garden.
- Steps: (1) Ask who leads sessions, whether staff are paid or volunteers, and whether staff have mental health, safeguarding and first aid training (garden leaders themselves named these needs) [source: Sustain 2019; NASP toolkit]. (2) Ask about DBS or equivalent checks, health and safety, duty of care [source: Sustain 2019]. (3) Ask about quality frameworks; the toolkit names the Green Care Quality Mark and the UK Association for Social and Therapeutic Horticulture practice standards, and Trusted Provider checklists [source: NASP toolkit]. (4) Ask how they handle someone who becomes distressed, and how inappropriate referrals and changing needs are dealt with [source: NASP toolkit]. (5) Visit if you can [source: NASP toolkit].
- Example language (illustrative, to a garden coordinator): "If someone I refer has a hard day on site, what would your team do, and who would you contact?"
- Watch for: no answer on safeguarding or distress; claims of clinical treatment by untrained staff. Working: clear, specific answers.
4.5 Referral and warm handover
- Purpose / when: Phase B to C.
- Steps: (1) With consent, refer through the local link worker or directly to the provider, or support self-referral [source: NASP, Thrive; NHS England]. (2) Include the provider's required information: relevant history, needs and preferences, enough to judge fit [source: NASP toolkit]. (3) Arrange the warm-handover sequence: your introduction, a one-to-one chat with the provider, a site visit before joining [source: NASP toolkit]. (4) Agree who the provider contacts if worried.
- Example language (illustrative): "I can introduce you to the coordinator first, so the first time you walk in someone knows your name."
- Watch for: referrals sitting unanswered (capacity is a common barrier) [source: Sustain 2019]; follow up. Working: a date for a visit.
4.6 Preparing for first attendance
- Purpose / when: Phase C, especially with social anxiety, low mood or trauma.
- Steps: (1) Use what the provider offers: pre-meet, drop-in, taster session, nature buddy volunteer, walkthrough video, separate induction for referred people [source: NASP toolkit]. (2) Rehearse the practicalities: route, clothes for the weather, what to bring, how to leave early. (3) Name the likely feared moment (arriving, introductions, not knowing what to do) and plan one coping step for it. (4) Set the goal as turning up, not performing.
- Example language (illustrative): "Success on day one is getting through the gate. If you leave after ten minutes, that still counts and we'll talk about it."
- Watch for: avoidance disguised as weather or timing. Working: attendance, even brief.
4.7 Behavioural activation framing
- Purpose / when: Phase D, for low mood, withdrawal, loss of routine (cross-refer II 040).
- Steps: (1) Link a growing task to a value (care, usefulness, belonging, creativity). (2) Schedule it as a planned activity the client chooses. (3) Rate mood or sense of achievement before and after in the client's own terms. (4) Review and adjust. Do not set durations, frequencies or exertion levels; physical limits go to the physician or a qualified exercise professional [synthesis].
- Example language (illustrative): "Watering the seedlings mattered to you because they rely on you. What did your mood do before and after?"
- Watch for: all-or-nothing scheduling; pain or exhaustion after sessions (route to physician). Working: mood or mastery shifts the client notices.
4.8 Debriefing garden experiences
- Purpose / when: every session in Phase D.
- Steps: (1) Ask what happened, whom they spoke to, what they did with their hands. (2) Ask what they noticed in body and mood. (3) Explore any difficult moment (criticism, being left out, a task failing). (4) Draw out a link to therapy goals. (5) Plan the next attendance [synthesis].
- Example language (illustrative): "Take me there: what were you doing when you felt that shift?"
- Watch for: reports only of tasks, never of people (isolation persisting inside the group); interpersonal patterns repeating on site. Working: richer, more varied reports.
4.9 Seasonal cycle and growth as meaning
- Purpose / when: Phase D, when the client brings garden imagery or struggles with patience, loss or change [synthesis].
- Steps: (1) Notice the client's own images (dormancy, pruning, compost, first shoots). (2) Ask what the image says about their situation. (3) Leave it with them; do not add a lesson. (4) Return to it later if they do.
- Example language (illustrative): "You said the bed looks dead in February but you know what's under it. Does that fit anything else for you?"
- Watch for: imposed metaphors that feel glib, especially in grief. Working: the client uses the image unprompted.
4.10 Tolerating slow reward and failure
- Purpose / when: perfectionism, hopelessness, self-criticism; after slugs, frost, drought or neglect of a plot [synthesis].
- Steps: (1) Gather the facts of the setback. (2) Separate what was in the client's control from weather, pests and luck. (3) Examine the self-critical thought and an alternative. (4) Plan the next attempt or deliberately let the crop go.
- Example language (illustrative): "Every grower on that site lost something this year. What would you tell a neighbour whose beans failed?"
- Watch for: setbacks used as proof of worthlessness; abandoning the plot. Working: the client can laugh at a failure or try again.
4.11 Social connection and reciprocity
- Purpose / when: loneliness, social anxiety, recent bereavement or migration. Allotment social contact helps reduce loneliness [source: NAS]; nature-based social prescribing is "particularly shown to reduce loneliness" [source: NASP green toolkit page]; Incredible Edible frames inclusion as "If you eat, you're in" [source: The Ecologist 2014].
- Steps: (1) Identify one low-stakes exchange (swapping seedlings, asking a neighbour's advice, sharing surplus, a tea-break chat). (2) Plan it. (3) Debrief what happened and what the client predicted. (4) Build towards a role in the group (watering rota, seed saving, welcoming newcomers) [synthesis].
- Example language (illustrative): "You've got too many courgettes. Who on the site could you offer some to, and what do you imagine they'd say?"
- Watch for: site politics and conflict between plot-holders; exploitation of a willing volunteer; burnout in helpers. Working: named people in the client's reports.
4.12 Food, eating and disordered-eating screen
- Purpose / when: any time food growing touches eating, weight, body or control; before referring a client with a known eating disorder [synthesis].
- Steps: (1) Ask neutrally what food from the garden would mean to them. (2) Listen for rigid rules, "clean" or "pure" eating, fear of foods, compensatory exercise, or using physical work to control weight. (3) If present, screen properly and refer to the treating team, a registered dietitian or an eating-disorder service; in the US, signpost the National Alliance for Eating Disorders. (4) Do not give diet plans, calorie, weight or macronutrient targets, fasting or supplement advice; keep cooking and sharing as social and cultural material, not nutrition therapy. Cross-refer the nutrition guide (124, this domain).
- Example language (illustrative): "Growing food can bring up a lot about eating. How does it sit with you to take home something you grew?"
- Watch for: garden labour becoming exercise compulsion; harvests becoming a vehicle for restriction. Working: food talk that is about pleasure, sharing or heritage.
4.13 Site safety briefing (soil, tools, weather, wildlife)
- Purpose / when: Phase C, and whenever a client, child or vulnerable adult will handle soil or produce.
- Steps: (1) Direct the client to the site's own induction and rules first [synthesis]. (2) Soil: urban soil can contain lead, especially near older painted buildings, busy roads or former industrial sites; the San Francisco public-health guidance favours raised beds of clean soil over a barrier, not building beds from treated or painted materials, wearing gloves in existing soil, washing hands after soil work, using lead-free hoses, and close supervision of young children, who face the greatest risk because exposure is mainly hand-to-mouth [source: SF Department of Public Health 2017]. Route testing questions to the local environmental health service. (3) Tools and lifting: use the site's tool rules; ask staff to show safe handling; pace bending and lifting by how the body feels; take pain or injury to a clinician [synthesis]. (4) Weather and sun: plan clothing, shade, water and an indoor or cancellation option [synthesis]. (5) Stings, plants and ticks: carry any emergency allergy plan the client already has; check for ticks after work in long grass; know which plants irritate skin; ask the physician or practice nurse whether routine vaccinations are up to date for soil work [synthesis].
- Example language (illustrative): "Before your first day, let's check: does the site have an induction, and do you know where the gloves and first-aid kit are?"
- Watch for: clients with cognitive impairment or children unsupervised near soil, tools or ponds. Working: the client can describe the site rules.
4.14 Delivering sessions in a garden yourself
- Purpose / when: only where you are trained, permitted by your employer and insured for outdoor work; for STH, training is offered by bodies such as Thrive (which reports training people to deliver STH) [source: NASP, Thrive]; practitioner standards include the UKASTH practice standards [source: NASP toolkit].
- Steps: (1) Contract in writing: location, what happens if others are present, how you will greet each other if you meet people the client knows, the weather plan and indoor alternative, how sessions end, what is recorded [synthesis]. (2) Confidentiality outdoors: choose a quiet corner, agree a signal to pause talk when people pass, and make clear that being seen together can reveal therapy [synthesis]. (3) Touch: none is needed for gardening; if a hand-over-hand demonstration is proposed, ask first, allow refusal and stop at any time; never sexual [synthesis]. (4) Keep clinical notes and risk procedures as in the clinic. (5) Check with your insurer and professional body that garden-based work and any tools or produce are covered; confirm the site's own public liability and risk assessment [synthesis]. (6) If you are also a volunteer or plot-holder there, manage the multiple relationship (APA Ethics Code Standard 3.05).
- Example language (illustrative): "If one of the volunteers comes over, I'll just say we're working on the beds. Is that all right with you?"
- Watch for: sessions drifting into gardening without therapy, or into friendship. Working: the client uses both the task and the conversation.
4.15 Liaison with garden staff
- Purpose / when: Phase C to E, with written consent.
- Steps: (1) Agree with the client what may be shared and with whom. (2) Give staff only what they need for fit and safety [synthesis]. (3) Agree an escalation route if staff are worried, and remember gardens do not provide clinical support for acute illness [source: NASP toolkit]. (4) Check in at agreed points about attendance and any concerns. (5) Thank and respect staff time; capacity is limited [source: Sustain 2019].
- Example language (illustrative, to the client): "I'd like the coordinator to know who to call if you're unwell on site, and nothing else. Does that feel right?"
- Watch for: staff being asked to act as therapists; information passing beyond consent. Working: clear, rare, useful contact.
4.16 Measuring and reviewing change
- Purpose / when: Phase D reviews.
- Steps: (1) Keep your routine therapy outcome measures. (2) Ask what the provider uses; ONS4 was used in the national programme, with some sites finding it triggering and choosing the Outcomes Star or co-designed measures [source: NASP toolkit; NASP 2024 evaluation news]. (3) Add the client's own markers (sleep, days out of the house, people spoken to). (4) Review against the plan from 4.1.
- Example language (illustrative): "When we started you said you hadn't spoken to anyone outside your flat for a week. How many people did you talk to on site this month?"
- Watch for: measurement burden spoiling the activity [source: NASP toolkit]. Working: changes the client recognises as theirs.
4.17 Adapting for access and inclusion
- Purpose / when: disability, chronic illness, language, culture, gender, caring duties.
- Steps: (1) Ask the provider about paths, toilets, transport, raised beds or sensory gardens [source: NASP toolkit; NAS]. (2) Look for single-gender sessions, childcare, group travel, sessions at varied times and information in other languages [source: NASP toolkit]. (3) Help the client troubleshoot transport [source: NASP toolkit]. (4) Explore cost; the toolkit notes models with free initial sessions then sliding-scale contributions [source: NASP toolkit].
- Example language (illustrative): "Would a women-only group or one with a crèche make this easier?"
- Watch for: the client blaming themselves for barriers that are structural. Working: a concrete adaptation in place.
4.18 Cultural meaning, heritage crops and migration
- Purpose / when: migrant, refugee, rural-origin or diaspora clients; clients whose family farmed or lost land [synthesis].
- Steps: (1) Ask what was grown and eaten at home and who did the growing. (2) Use the DSM-5-TR Cultural Formulation Interview where cultural identity, migration or loss is central [uncertain: not verified]. (3) Explore what growing those plants now brings: comfort, grief, pride, conflict. (4) Support finding gardens or groups where heritage crops and languages are welcome.
- Example language (illustrative): "What did your grandmother grow, and what is it like to see that plant come up here?"
- Watch for: grief surfacing through smell, taste and seasons; land loss linked to trauma. Working: the client tells their story through the garden.
4.19 Loss of the plot, grief and climate distress
- Purpose / when: loss of a plot (eviction for non-cultivation, site sale, illness), death of a fellow gardener, crop loss to drought or flood, eco-anxiety voiced in the garden [synthesis].
- Steps: (1) Treat the loss as a real loss, including identity and routine. (2) Explore what the plot held. (3) Look for continuity (a shared plot, container growing, another group). (4) For climate distress, validate, separate action from rumination, and consider groups described in the eco-anxiety guides of this domain.
- Example language (illustrative): "That plot was where you went after your husband died. Losing it is losing more than vegetables."
- Watch for: prolonged or complicated grief; hopelessness about climate turning into risk. Working: the client finds a way to keep growing or to mourn.
4.20 Children, families and school gardens
- Purpose / when: family therapy, child clients, parents seeking shared activity [synthesis].
- Steps: (1) Check the setting's safeguarding policy and staff checks [source for checks: Sustain 2019]. (2) Brief parents on supervision near soil (lead risk is greatest for young children), tools, water and ponds [source for lead: SF Department of Public Health 2017; otherwise synthesis]. (3) Use shared tasks to observe and coach parent-child interaction. (4) Obtain consent from parents and assent from the child; never identify a child in any report or photo shared by the project.
- Example language (illustrative): "Could you two plant one row together this week, and tell me who decided where the seeds went?"
- Watch for: safeguarding concerns disclosed on site; follow your local procedure. Working: easier, warmer shared activity.
4.21 Step-down and ending
- Purpose / when: Phase E.
- Steps: (1) Map the routes from structured or STH programmes to community groups or an own plot [source: NASP toolkit]. (2) Consider joining a waiting list early, given long waits [source: NAS]. (3) Review what the client will keep doing without therapy. (4) Plan for winter and setbacks. (5) End or space therapy [synthesis].
- Example language (illustrative): "When the programme ends in autumn, where will you be growing next spring?"
- Watch for: the end of a funded programme leaving a gap. Working: a named next place.
5. Handling problems
The sources address capacity, referral and access barriers; most of the clinical guidance below is [synthesis].
- Referral goes nowhere. Capacity and time are the most common barriers garden leaders report, and referral routes are often unclear [source: Sustain 2019]. Response: phone the coordinator, ask the link worker for the local directory, offer a second option, and keep a self-referral route open.
- Client agrees but never goes (non-adherence). Response: shrink the step (a visit with you or a buddy, a taster session, a drop-in) [source for options: NASP toolkit]; examine the predicted catastrophe; check practical barriers (transport, cost, clothes, childcare) before assuming low motivation [synthesis].
- "I'm not a gardener" / it feels imposed (resistance). Response: return to 4.1; the activity may be wrong. Offer alternatives within green social prescribing (walking, conservation work) or outside it; never make therapy conditional on it [synthesis].
- Overwhelm on site (crowds, noise, criticism, too many instructions). Response: agree a retreat spot and an exit plan with the client and, with consent, with staff; reduce to a smaller group or quieter time; use grounding skills already learned in therapy [synthesis].
- Conflict with other gardeners or site rules. Allotment and community sites have rules and committees; disputes over boundaries, untidiness or non-cultivation are common [synthesis]. Response: treat it as interpersonal material; rehearse assertive requests; help the client understand the tenancy rules; do not intervene with the committee unless asked and consented [synthesis].
- Physical setbacks (pain, fatigue, flare-ups, injury). Response: pause, route to the physician or a qualified exercise professional or physiotherapist, look for adapted tasks or raised beds [source for raised beds: NAS]; avoid any target setting [synthesis].
- Weather and seasons. Winter, heat and rain cut attendance. Response: plan indoor tasks the provider offers (seed sowing, planning, tool care) and keep therapy running through gaps; for heat, prioritise shade, water and rest and follow site guidance [synthesis].
- Escalating risk or crisis while on site. Gardens do not provide clinical support for acute illness [source: NASP toolkit]. Response: an agreed escalation route (4.15); suspend participation if needed; standard risk assessment and safety planning. Crisis resources: 988 in the US; Samaritans 116 123 in the UK and Ireland. If tools, chemicals or water are part of a safety concern, agree storage or avoidance as lethal-means counselling [synthesis].
- Food becomes a vehicle for disordered eating or compulsive activity. Response: 4.12; involve the treating team, a registered dietitian or an eating-disorder service; in the US, the National Alliance for Eating Disorders; no diet, fasting or supplement advice [synthesis].
- Soil or produce safety worries. Response: route to the site's rules and the local environmental health service; raised beds and clean soil are the published remedy for contaminated urban soil [source: SF Department of Public Health 2017].
- Rupture: "You sent me there to get rid of me." Response: name it, apologise for any part you played, restate that the garden adds to therapy rather than replacing it, and repair before re-planning [synthesis].
- Dual-role strain (you are a plot-holder or volunteer where your client goes). Response: discuss in advance how you will meet; consider a different site for one of you; consult supervision; document (APA Ethics Code Standard 3.05).
- Garden staff out of their depth. Garden leaders worried that referred people may have higher needs than expected and named first aid, mental health and safeguarding training as needs [source: Sustain 2019]. Response: refer to staffed or STH settings for higher needs; offer consultation only within your role; do not supervise volunteers clinically without agreement [synthesis].
- Funded programme ends. Response: plan step-down early [source: NASP toolkit], including waiting-list registration for an allotment [source: NAS].
- Loss of the plot or of a fellow gardener. Response: 4.19; screen for prolonged grief where loss is persistent and disabling [synthesis].
- Safeguarding concern about a child or vulnerable adult on site. Response: follow local safeguarding procedure; report to the project's safeguarding lead and statutory services as required; do not identify individuals beyond what reporting needs [synthesis].
