This year feels significant for our profession in many ways. As the Pioneers & Pathways signature experience continues taking shape for the 2026 AHTA Annual Conference in San Francisco, we have been reaching out to leaders across the profession to help shape and participate in this experience. As part of that process—and increasingly intrigued by the stories, perspectives, and leadership that helped shape the profession across the years—I began revisiting past newsletters, reflections, and publications from throughout AHTA’s history.

When was the last time many of us truly sat down and revisited publications from the early years of AHTA? Or reflected on the voices, persistence, and skill sets woven throughout those pages?

What started for me simply as preparation for a conference experience quickly became something much deeper. It became a reflection on the advocacy, vision, persistence, and unwavering commitment of AHTA members who, across many decades, helped sustain and strengthen the professional field across generations.

This organization is incredibly rich in thought leadership, lived experience, and impactful voices that helped carry the profession of horticultural therapy through changing times. And honestly, something about revisiting those messages ignited a much deeper appreciation for just how many individuals stayed committed to this profession long before recognition, resources, educational pathways, and professional infrastructure were where they are today.

Across decades of leadership, there is a remarkable consistency in what has been called for: continuing to strengthen the credibility of the profession, expanding access to horticultural therapy and therapeutic horticulture experiences, deepening interdisciplinary collaboration, supporting education and research, and ensuring the people we serve remain at the center of everything we do.

What became increasingly clear while revisiting these reflections is that horticultural therapy has never been carried forward by one voice, one background, or one pathway into the profession. It has been shaped by people from all walks of life who continued showing up with ideas, advocacy, mentorship, volunteerism, research, creativity, and an enduring belief in the power of the people–plant connection.

That spirit sits at the center of Pioneers & Pathways. This experience is meant not only to honor the individuals who helped shape and sustain the profession across generations, but also to help create meaningful pathways forward for emerging professionals through mentorship, internship connections, professional development tools, and conversations surrounding the historic launch of Board Certification.

There is already tremendous excitement surrounding the 2026 Annual Conference —from the caliber of proposals and research being presented, to the innovation, collaboration, and vision continuing to emerge across our professional field. We hope you will join us for this meaningful experience and be part of the continued momentum helping shape the next chapter of the profession.

🍃 What is the AHTA Certification?

The AHTA Certification is a formal recognition that an individual has met established professional standards in horticultural therapy. It assures employers, clients, and the public that certified professionals possess the knowledge, skills, and experience necessary to practice effectively and ethically.

The certification process includes: - Defined education requirements - Verified professional experience - Successful completion of a comprehensive examination

Certification vs Certificate - A certificate is awarded upon completion of an educational program (e.g., AHTA-accredited horticultural therapy courses) - Certification is a formal, third-party evaluation process that includes eligibility requirements, testing, and ethical standards.
✅ A certificate does not equate to professional certification

🌱 Exam Content: Core Domains

The HT–BC examination is based on six key professional domains identified through the large-scale 2022 Job Task Analysis:

Horticulture
Treatment Planning
Program Planning & Activity Design
Managing Human Resources
Business Practices, Safety & Ethics
Professionalism & Scholarship

These domains reflect the essential knowledge areas for effective horticultural therapy practice.

🌼 Who is this Certification For?

The Horticultural Therapist–Board Certified (HT–BC) credential is designed for individuals seeking formal recognition as professional horticultural therapists.

It is expected that the HT–BC will eventually replace the current HTR designation as the primary credential in the field.

🌳 Why Certification Matters

Certification supports both individual professionals and the field as a whole:

Professional Credibility – Verifies expertise and ethical practice
Standardized Practice – Aligns professionals with best-practice guidelines
Demonstrated Competence – Combines education, skill development, and experience
Stronger Recognition – Builds public awareness and professional identity
Ongoing Growth – Requires continued learning and engagement

Together, certification strengthens the roots of horticultural therapy for future generations.

🌷 Frequently Asked Questions

What will happen to the HTR designation? AHTA will stop accepting new HTR applications approximately three months before the HT–BC exam launch (anticipated July 1, 2026). Current HTRs and HTMs may continue using their designations. The HT–BC credential is optional for existing professionals, but will be required for new applicants after that point.

Will this affect the THP designation? No. The Therapeutic Horticulture Practitioner (THP) designation will remain unchanged.

How do I know if I’m eligible for the HT–BC exam?
Eligibility will include education and experience criteria like HTR requirements, with an additional pathway for those in allied professions. These pathways align with national standards for professional certification. Specific eligibility info: https://www.ahta.org/board-certification

Will there be study materials or prep courses for the exam? AHTA will provide an Exam Handbook with recommended resources, sample questions, and guidance to be ready before August 1. The exam will be based on what qualified practitioners are expected to know through training and experience.

How long is the certification valid?
The HT–BC is expected to be valid for five years. Renewal will include continuing education and ongoing professional activity.

Therapeutic Goals

Fine Motor Coordination: Handling delicate orchids, tying supports, and arranging them on branches.
Cognitive Engagement: Enhancing focus, memory, and problem-solving while learning orchid care and placement.
Emotional Wellbeing: Fostering creativity, a sense of accomplishment, and a calming, intimate connection with nature.
Social Connection: Encouraging collaboration, conversation, and shared experiences.
Mindfulness & Sensory Awareness: Engaging sight, touch, and smell to promote relaxation and present-moment focus.

Materials

Orchids: Best Varieties: Vanda, Dendrobium, Cattleya, Brassavola, Oncidium, Phalaenopsis
Mounting Supplies: Sphagnum moss, fishing line, pantyhose, soft garden ties
Tools: Scissors, gloves (optional for moss or rough tree bark), watering can or spray bottle, ladder or step stool (if safe and accessible)

Directions

Prepare the Orchid - Gently remove the orchid from its pot and remove any bark or medium between roots. Cut away unhealthy roots.
Wrap the Roots (Optional in Very Humid Climates) - Create a ball of sphagnum moss and gently wrap the orchid’s roots around it to retain moisture in less humid climates. In very humid regions (zones 10–12), this step is optional—orchids can be tied directly to the tree. Secure the moss or roots with fishing line, pantyhose, or soft garden ties, making sure the plant is stable but not constricted. It is advisable to demonstrate proper handling to avoid damaging roots or leaves.
Select a Tree - Choose a tree with rough bark (such as oak) and dappled shade to protect leaves from direct, harsh sun. Avoid dead, weak, or brittle branches.
Position and Attach the Orchid - Place the orchid in the crotch or fork of a branch for stability. Wrap roots (or moss-covered roots) around the branch using fishing line, pantyhose, or soft garden ties. Ensure the orchid is stable and won’t fall but avoid constricting the roots to allow natural growth.

If participants cannot safely reach the branch, staff may hang the orchid while participants observe and guide placement.

Modifications for Different Populations

Mobility Adaptations: Use low-hanging branches or table-mounted displays to avoid ladders.
Cognitive Support: Break the activity into short, clear steps and provide visual cues or demonstrations.
Seated Participation: Allow participants to sit while arranging orchids or handling moss.
Step Simplification: Focus on one step at a time (e.g. wrapping moss, then securing plant).
Hand-over-Hand Assistance: Staff can guide hands gently for wrapping or tying.
Visual & Tactile Cues: Use color-coded ties or labeled materials to simplify sequencing.
Repetition & Reinforcement: Encourage repeating steps to build confidence and mastery.
Group Collaboration: Pair participants together to build teamwork skills and reduce frustration.

Safety & Considerations

Ladder / Height Safety: Always ensure ladders or step stools are on stable, level ground. Staff should supervise all work above shoulder height.
Allergies / Sensitivities: Check for allergies to orchids, moss, or tree bark. Gloves recommended for sensitive skin.
Tree / Branch Safety: Avoid dead or brittle branches; do not tie too tightly to prevent damage to the tree or orchid.
Sun / Weather Exposure: Avoid bright, direct afternoon sun; consider wind exposure.
Water / Slippery Surfaces: Watering may create slippery areas—ensure safe footing.
Insects / Wildlife: Orchids may attract bees or ants; observe carefully.
Temperature Monitoring: Monitor seasonal temperatures and move orchids indoors when nighttime temps fall below 55°F.
Successful Growth: Encourage daily or every-other-day misting in summer

Reflection

Just as orchids are given the freedom to grow as nature intended, participants are encouraged to reflect on their own potential to flourish when freed from constraints. Take a moment to observe your orchid and consider how its growth mirrors your own potential.

Questions to ask:

As you watch your orchid sway freely in the branches, consider:

What does freedom to grow mean for you?
Where in your life could you allow yourself more space to bloom?
