President's Message	News & Events	Horticultural Therapy Certification	HT Activity	Sponsorship

As we begin a new year, one thing is abundantly clear: the horticultural therapy profession is growing—in numbers, in reach, and in collective energy. Membership is expanding, engagement is deepening, and truly impactful professional connections are forming across healthcare, human services, education, environmental stewardship, and allied professional fields. This month, AHTA is focusing on collaboration across disciplines, generations, perspectives, and geographic regions—embracing both national and global connections.

As AHTA members know, horticultural therapy is inherently interdisciplinary, bringing together horticulture, human science, psychology, and environmental connection. Our Board of Directors, member base, and executive leadership are actively building meaningful collaborations that reflect this integrative foundation and strengthen how we practice, lead, and serve.

This collaborative spirit is energizing. It is strengthening the foundation of our profession—inspiring the reach of horticultural therapy and therapeutic horticulture across communities.

The AHTA 2026 Annual Conference ‘Call for Sessions’ is now open, continuing our long-standing tradition of interdisciplinary exchange and high standards in conference programming. At the same time, the ‘Growing Impact’ Youth Wellness Campaign is bridging allied professions with AHTA leadership and member-led initiatives—building shared alignment and momentum around youth well-being through horticulture and therapeutic approaches, nationwide and globally.

We are especially excited to welcome Jennifer Jewell, author of The Earth in Her Hands and creator/host of Cultivating Place, as our keynote speaker for the AHTA 2026 Annual Conference. Her voice and storytelling reflect the people–plant connection and collaborative spirit at the heart of our professional field. This year’s in-person conference will be a signature experience —within inspiring, plant-rich environments unique to San Francisco, experiential learning settings, and expert-led forums.

As we center on collaboration this month, we invite you to take part in the work unfolding across AHTA. Submit a presentation proposal for the 2026 Annual Conference, be an exhibitor at the Conference, align your efforts with the ‘Growing Impact’ Youth Wellness Campaign with events resuming in March 2026, or lend your time and expertise to support the successful launch of board certification. When we collaborate and move forward together, our combined strength exponentially amplifies.

“One light feeds another. One strong family lends strength to more. One engaged community can ignite those around it. This is the power of the light we carry.”

Publishing in a journal can seem to be an intimidating process, but taking the effort brings a range of benefits including lessons learned during the process, contributing to the field of HT/TH, and building one’s CV. Join us as we explore the process of publishing in AHTA’s Journal of Therapeutic Horticulture (JTH). The Journal has recently gone to an open access model which greatly increases visibility and allows access to the journal content for all. While JTH publishes research, there are additional sections which allow authors to share information and knowledge in a scholarly fashion to further advance our field. So, if you have interest in publishing in JTH, this webinar will provide a roadmap to help you along the way.

The countdown to the certification exam for the Horticultural Therapist–Board Certified (HT–BC) credential continues. The American Horticultural Therapy Association (AHTA) is pleased to have announced the launch of its first professional credentialing exam, scheduled to take place 9 months from now — in October 2026.

While some details are still being finalized, we want to keep our community informed and share what you can expect as this important credentialing process takes shape.

🍃 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 to sit for the certification exam? Eligibility will include education and experience criteria similar to HTR requirements, with an additional pathway for those in allied professions. These pathways align with national standards for professional certification.

Will there be study materials or prep courses for the exam? AHTA intends to provide recommended resources, sample questions, and guidance. 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/or ongoing professional activity.

Thank you for being a vital part of the growing field of horticultural therapy.

Partnership supports growth.

At AHTA, collaboration across disciplines is essential to growing not only our profession—but public understanding of it. Our professional work, rooted in the powerful people–plant connection, has the capacity to positively change lives in healthcare, education, vocational, and wellness settings across the country and around the world. While its impact is clear to those who experience it firsthand, for many in the general public this work remains unfamiliar.

Partnership helps us change that.

Through strategic collaborations, AHTA is increasing public awareness—sharing stories, evidence, and real-world impact that highlight how this unique professional field supports mental health, resilience, physical mending and rehabilitation, and overall well-being. Sponsorship allows us to extend this message even further, amplifying it across healthcare systems, wellness spaces, community organizations, educational systems, and allied professions.

In the upcoming weeks, AHTA will be sharing new sponsorship guides and engaging with organizations that share our commitment to collaboration, innovation, and meaningful impact. These partnerships play a vital role in expanding awareness, supporting the continued advancement of professional standards through board certification, and ensuring more people benefit from the healing power of plants.

Watch for our upcoming sponsorship opportunities and join us in expanding the visibility of our professional field.

ACTIVITY DESCRIPTION: Participants will make biodegradable seed pots for planting Forget Me Not seeds, these associated with Alzheimer’s disease & dementia.

The facilitator begins session by sharing the connection between Forget Me Not flowers & dementia/Alzheimer’s. Several methods of creating seed pots for these or other seeds are presented & selected based on participant needs, goals and attention skills. Seed pots can be made from toilet paper or paper towel tubes, cardboard egg cartons &/or newspaper; each method is described in the THAD. The activity can include sustainable gardening practices. Materials: toilet rolls, scissors, potting soil, seeds, water, cardboard egg cartons, newspaper, jar or other form for creating shape. Alzheimer’s societies may donate seeds.

Making biodegradable seed pots is appropriate for most populations and can be modified to accommodate people living with dementia, memory loss or other health challenges. For people living with dementia, and depending on their abilities, propensity for putting items in their mouths or using scissors, parts of the activity can be undertaken excluding soil, seeds or scissors if these may cause safety concerns. Making the seed pots can be good physical activity for strengthening fingers, hand movements and hand-eye coordination. Making seed pots can also contribute to sense of accomplishment and contribute to a group service project where others plant the seeds and grow the Forget Me Nots in the seed pots. Additional therapeutic goals are identified in the THAD.

Tips for Practice

The use of plants, essential for TH sessions, can be integrated into this activity where information about the flower as a symbol of Alzheimer’s societies can expand participants’ understanding of people-plant connections. “The tiny blue five petalled flowers with yellow centers, known as Forget Me Nots, have become symbols of Alzheimer’s disease awareness across the globe. It is Myosotis spp. that is featured on pins, badges and educational materials. Forget Me Not flowers, from the Boraginaceae family of plants, in the Myosotis genus consists of 153 species” (Fleming & House, 2025; Lee, 2024). Making biodegradable seed pots, then planting Forget Me Not seeds can reinforce multi-domain goals in physical, cognitive, psychological and sensory areas.

Lesley Fleming, HTR leads the Nova Scotia and the Florida Horticulture for Health Networks. Her recent work has included leading the collaborative THAD project, FLHHN’s Resource Hub, and 2024 Journal of Therapeutic Horticulture articles on TH Goals co-authored with Elizabeth Diehl and Kathryn Grimes and Positive Impacts from COVID-19 on Gardening and HT.
