President’s Message: Progress Happens Between the Milestones

In horticulture, nodes are visible markers of growth. They are the points where leaves and buds emerge, and new growth begins. But a plant does not move forward from node to node without what happens between them. Within the internodes, cells divide and elongate, tissues develop and strengthen, and the stem extends to support what comes next.

The same can be said of AHTA and our profession. Our milestones matter. They mark significant achievements and help us see how far we have come, but they are only possible because of the work that happens between them—the conversations, decisions, collaborations, problem-solving, and countless contributions that steadily move our profession forward.

Progress happens between the milestones, and there is a great deal happening in the space between ours.

Every profession depends on people who choose to contribute beyond their daily work. They bring their professional expertise, experience, and time to efforts that often happen behind the scenes, but that help shape where the profession is going. That is stewardship.

We see it across AHTA. The launch of board certification represents years of thoughtful work by professionals who generously contributed their expertise and time to the development of this important credential. Our Annual Conference will bring our professional community together in October, but the few days we spend together are made possible by more than a year of planning, collaboration, and dedicated work behind the scenes. And new strategic partnerships are forming from relationships and groundwork laid over years—creating opportunities to expand the reach and impact of horticultural therapy and therapeutic horticulture.

Taken together, these efforts signal something larger: a profession actively moving forward. Just as the nodes along a plant stem are connected by the living tissue that sustains continued growth, our milestones are part of something continuous. Each contribution creates capacity for what comes next and helps shape how our profession unfolds.

To everyone who has contributed their expertise, experience, and time to that work, thank you. The milestones we celebrate belong to all of us because they are built by all of us.

And there is much more ahead. AHTA’s work is expanding, and so are the opportunities to be part of it. Join a work team. Pursue board certification. Attend the Annual Conference. Share your expertise, ideas, and perspective. There are many ways to contribute, and we welcome your voice, your direction, and your dedication as we shape where our profession is going.

Progress happens between the milestones. Be part of what happens next.

With Gratitude, 

Kelly Warnick, HTR, JD

President, American Horticultural Therapy Association

🍃 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:

1. Horticulture
2. Treatment Planning
3. Program Planning & Activity Design
4. Managing Human Resources
5. Business Practices, Safety & Ethics
6. Professionalism & Scholarship

These domains reflect the essential knowledge areas for effective horticultural therapy practice. Please see the Exam candidate handbook for more specifics on the knowledge areas. https://www.ahta.org/htbc-getcertified 

🌼 Who is this Certification For?

The Horticultural Therapist–Board Certified (HT–BC) is for:

• Professionals ready to elevate their credibility and be formally recognized as credentialed horticultural therapists—raising the bar for the entire profession.
• HTRs, HTMs, and allied professionals with licensure or certification in Human Sciences or Horticulture who want to align with the emerging gold standard.
• Practitioners committed to excellence, ensuring they are fully equipped to deliver high-quality, research-based therapeutic interventions.

🌳 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.

Opening Reception & Moth Hour — Sponsored by HT Institute
Join colleagues from across the profession for an evening of connection, celebration, and community as we kick off an unforgettable conference together. Stay tuned for the unique experience we are creating.

Plants & Paws — Sponsored by Ball Horticultural Company

Outreach & Strategic Partnerships

This evolution also reflects what we have heard from our members. Time and again, members have identified increasing public awareness of both our professional field and AHTA as an important priority. By broadening the team’s focus, we are intentionally creating new pathways to engage organizations, professionals, and communities that share our commitment to health, wellness, and nature-based interventions.

Alphabet Garden

 Prepared by:

Karen Haney, M.A., HTR

Florida Horticulture for Health Network

Excerpted from University of Florida Therapeutic Horticulture Activities Database 2026

DESCRIPTION: Participants will plan & plant an alphabet garden using plants/names beginning with the letters of the alphabet.

This multi-session activity can be undertaken by the same group of participants over a series of sessions or it can be divided and shared with other groups or grade levels (classes) with facilitator assigning specific tasks to each group. These types of themed gardens are popular and relevant for school gardens, social service agency gardens, and extension office demonstration gardens. Step by step instructions are listed in THAD Alphabet Garden (research plants, list 26 alphabet letters on chalkboard, gather plant prior to session, plan for installation and maintenance). 

Therapeutic horticulture goals for physical challenges will depend on participants. For example, if participants have cerebral palsy or use wheelchairs with lower body paralysis, handling and planting specimens may occur in raised beds or elevated containers (boots attached to fence at waist height) expanding the functional movement of upper torso, hands and arms. For people with mobility challenges, walking in the garden area during and after the garden installation can offer opportunities to navigate uneven surfaces, consider and practice strategies for moving light items (some plants, signage, water can) and build confidence in public spaces like gardens. Additional therapeutic goals are identified in THAD Alphabet Garden.  

NOTES OR OTHER CONSIDERATIONS: It can be challenging to find plants A-Z that will thrive in a specific garden zone. Some plants may be viable in certain seasons and not year-round. Some of the more challenging letters/plants: J (juniper, joe pye-weed), K (kohirabi, kangaroo paw), Q (quince, queen Anne’s lace), X (xerophyte plants, xeriscape plants), and Z (zebra grass, zoysia grass) (Tilley, 2022). Having laminated photos of plants, labelled clearly with name and alphabet letter can be an option. Or using garden related items like rain barrel, hose or watering can may substitute for some letters.

SAFETY CONSIDERATIONS: Facilitators are responsible for knowing poisonous and toxic plants and plant parts (more detail in THAD).

Lesley Fleming, HTR leads the Nova Scotia and the Florida Horticulture for Health Networks, leads THAD initiative, and writes extensively on topics related to HT/TH and horticulture for health.
