• Partnerships with healthcare, rehabilitation, and social service organizations
• Adaptive tool and technique selection
• Program documentation and outcome tracking
• Staff and volunteer training in therapeutic techniques
• Professional development in horticultural therapy (HTR/HTM credentials)

Core Workflows

Program Design

1. Assess participant population: abilities, limitations, goals, interests
2. Define program goals aligned with therapeutic objectives:

Population	Goals	Example Activities
Older adults (memory care)	Sensory stimulation, socialization, reminiscence	Herb sensory walk, flower arranging, seed sorting
Physical rehabilitation	Fine/gross motor skills, endurance, balance	Potting, raised bed gardening, raking, walking paths
Mental health	Stress reduction, self-efficacy, mindfulness	Mindful garden walks, journaling, container gardens
Developmental disabilities	Vocational skills, social skills, routine	Greenhouse tasks, plant production, market preparation
Veterans	PTSD management, community, purpose	Garden construction, food production, peer mentoring
At-risk youth	Responsibility, teamwork, nature connection	Garden-to-table cooking, habitat projects, stewardship

1. Structure sessions: welcome, warm-up, core activity, reflection, cool-down
2. Plan for 6-12 week program cycles with progressive skill building
3. Document individual participant goals and progress

Accessible Garden Design

• Raised beds at 24-30 inches for wheelchair access; max reach depth 24 inches
• Paths minimum 48 inches wide, firm surface (compacted gravel or pavement), max slope 5%
• Accessible water sources within reach of wheelchair users
• Shade structures for heat-sensitive participants
• Sensory elements: fragrant plants, textured foliage, sound (water, wind chimes)
• Rest areas with seating every 100-150 feet along accessible routes
• Signage: large print (minimum 24 pt), high contrast, Braille where possible
• Non-toxic plant selections in all therapeutic areas

Adaptive Tools & Techniques

Challenge	Adaptation
Limited grip strength	Ergonomic handles, ratchet pruners, foam grip wrap
Wheelchair use	Raised beds, tabletop gardening, vertical gardens
Limited reach	Long-handled tools, elevated containers
Visual impairment	Tactile labels, fragrant plant borders, raised bed edges
Cognitive impairment	Visual task cards, simple step sequences, repetitive tasks
Fatigue/endurance	Short sessions, seated options, shade availability

Outcome Tracking

1. Use validated assessment tools where appropriate:

• Wellbeing scales (WHO-5, Warwick-Edinburgh)
• Mood assessments (visual analog scales)
• Functional assessments (grip strength, range of motion)
• Social engagement observation

1. Document attendance, participation level, and notable observations
2. Collect qualitative feedback from participants and caregivers
3. Report outcomes to partner organizations and funders
4. Use data to refine program design

Partnerships

• Healthcare: hospitals, rehabilitation centers, memory care facilities
• Social services: veterans organizations, mental health agencies, disability services
• Education: special education programs, transition programs
• Community: senior centers, community gardens, faith organizations
• Professional: American Horticultural Therapy Association (AHTA)

Credentialing Reference

Credential	Organization	Requirements
HTR (Horticultural Therapist Registered)	AHTA	Bachelor’s degree + 480 hrs supervised internship
HTM (Horticultural Therapy Master)	AHTA	HTR + 4000 hrs professional practice
CTRS (Certified Therapeutic Recreation Specialist)	NCTRC	Related credential for recreation therapy

Output Guidance

When producing program plans:

• Population description with abilities and goals
• Session plans with activities, timing, and adaptations
• Materials and adaptive equipment list
• Staff/volunteer requirements with training needs
• Evaluation plan with instruments
• Budget: materials, staffing, partner contributions

When producing garden design recommendations:

• Accessibility features with ADA references
• Plant selections prioritizing sensory engagement and safety
• Layout showing paths, beds, seating, water, and shade
• Material specifications for therapeutic durability
• Maintenance plan accounting for program schedule
