President's Message

Dear AHTA Community,

With spring in full swing as of April, 2025, we’re surrounded by nature’s promise of fresh starts and vibrant growth—a perfect parallel to the work we do in horticultural therapy. Just as sap rises to nourish budding trees, our efforts continue to fuel healing and connection through plants, and it’s
inspiring to see our field thriving.

This season reminds us that our strength lies in our 50+ years of deep shared roots and collective passion. The past month has shown how our community’s energy is sprouting in new directions, from raising awareness to deepening collaborations. Your work—whether tending to clients, sparking innovative projects, or sharing expertise—keeps pushing horticultural therapy into exciting new territory.

Take National Horticultural Therapy Week last month, March 16-22: your enthusiasm lit up our social media campaign! The posts, pictures, and clips you shared brought the magic of our profession to life—think touching stories of client breakthroughs and stunning shots of gardens in bloom. Every post was a seed, growing our reach and showing the world what we’re about.

Looking forward, let’s keep this momentum blooming. Dive in however you can, maybe pen a piece for our Journal of Therapeutic Horticulture, attend a webinar, or a community meeting, or pitch a story for the magazine. Every little bud of effort helps our field flourish and climb higher on the trellis of therapeutic practice.

Thanks for pouring your heart into this work. With your commitment to networking with the AHTA, together we’re not just planting seeds for the future, we’re growing a forest of impact for the people and places we touch. And you know what they say about trees and networking, they have all the best branches.

Matthew Janson CTRS, HTR,
AHTA President

Growing Wellness: Using Indoor Gardens in Horticultural Therapy

Join us for an enlightening presentation on how horticultural therapists are harnessing the power of grow lights to cultivate thriving indoor gardens. Growing Wellness: Using Indoor Gardens in Horticultural Therapy will explore how artificial lighting solutions can support plant growth in various settings, making horticultural therapy accessible in hospitals, rehabilitation centers, and other environments where natural sunlight is limited.

Discover practical strategies for selecting and utilizing grow lights to enhance therapeutic programs. Learn how these tools ensure year-round access to the healing benefits of plants, fostering connection, relaxation, and growth in those who need it most. Whether you’re a seasoned horticultural therapist or just beginning to explore the field, this presentation will provide valuable insights into integrating indoor gardening into wellness practices.

Meet Our Speaker: Tammy Brenner

Tammy Brenner, Program Manager of the Plant Growth Facilities at Colorado State University, brings a wealth of experience to this session. She plays a crucial role in supporting plant-based research by overseeing the allocation of greenhouse and growth chamber space for over 45 faculty members. She also manages repairs and improvements for the expansive 65,000-square-foot facility, ensures compliance with federal permits, and—her favorite part—fosters connections between the community and CSU’s innovative plant research.

Don’t miss this opportunity to gain expert knowledge on indoor gardening and its role in horticultural therapy. We look forward to seeing you there!

A Different Way of Knowing: Using Phenology to Garden Better
In an era of unpredictable weather patterns, where temperature swings and rainfall fluctuations can vary dramatically even within the same region, how can we cultivate deeper wisdom in the garden? The answer lies in phenology—the time-honored practice of observing the rhythms of nature to guide our gardening choices.
This session invites you to slow down and tune in to the subtle yet profound signals of the natural world. By studying the life cycles of plants, insects, and wildlife, you'll gain insights that no search engine or forecast can provide. Discover how to recognize nature’s cues—when the lilacs signal it’s time to plant, when the fireflies indicate soil warmth, and how pollinators reveal the health of your garden ecosystem.
Join us for an exploration of this centuries-old science, learning to work in harmony with nature’s calendar. Whether you are a seasoned gardener, a horticultural therapist, or someone who simply finds joy in the garden, phenology offers a richer, more intuitive way to cultivate resilience and connection in your green spaces.
Our speaker: Kristin Krokowski. Professor, University of Wisconsin Madison Division of Extension.
Her research and programming focus is on produce safety, farmers' markets and the success of small to medium size fruit and vegetable growers throughout Wisconsin. She is a Lead Trainer for the Food Safety Modernization Act Produce Safety Alliance Training.

She works locally and in collaboration with colleagues statewide to provide education and diagnostic services to the landscape industry and municipalities on ornamental horticulture.

Phase 1: Sowing Seeds! 

AHTA is grateful for the incredible turnout and enthusiastic participation in the ‘Growing Impact’ Youth Wellness Campaign Webinar Series!

Game: Gathering Nature’s TreasuresPhoto by SimplyBeyondHerbs & Pinterest

By Lesley Fleming, HTR & Maureen Bethel, BA, BEd, CAE
From Nova Scotia Horticulture for Health Network

Participants play a game finding items from nature to be shared with others - show and tell. Originally used with young children ages 3-6, this game can be adapted for all ages and abilities. Partnering with volunteers or older students as mentors for example, can provide safe parameters of knowing plants to avoid, sharp pinecones or paths that are too steep. Clearly defining the search/game area, possibly using the concept of staying within eyesight, will help younger participants. 
                                                                                               

Young children: The game can promote a sense of exploration, independence and curiosity, all of which address cognitive, social-emotional and physical development in a child. Nature-based play can also help reduce anxiety, improve self-regulation, and offer safe spaces for children to explore their physical world. Using the game in TH sessions with parent/family-child participants, the game can incorporate therapeutic goals related to fostering attachment, introducing the concept and need for risky play (leading children and parents to develop problem solving skills). This demonstrates the TH activity’s versatility with populations like parents/family groups. Step by step instructions are available in THAD (here). Materials: baskets or pails for collecting items, access to nature area with pinecones, flowers etc., whistle, gloves,wipes. SAFETY CONSIDERATIONS: Facilitators are responsible for knowing poisonous and toxic plants and plant parts (more detail in THAD).

 

Tips for Practice
Applications for other populations with physical therapeutic goals can target wide-ranging challenges like sedentary behaviors, sense of touch, bending and kneeling practice, and time outdoors breathing fresh air. These can be appropriate for different populations including people with nature deficit disorder, stroke recovery patients, recently diagnosed medical conditions where confidence in going outside has been affected, and people with developmental disabilities. Appropriate supervision is required and will vary by individuals and populations. Game rules can be adapted to increase physical activity, focus on specific physical challenges and appropriate for participants. An indoor application of the nature’s bounty game can accommodate people with mobility issues who are more comfortable indoors moving on smooth surfaces, or other reasons. THAD identifies relevant goals in five health domains for this, and each THAD activity.


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.

Maureen Bethel, BA, BEd, CAE is Manager of Daybreak Parent Child Centre, Community and Parent Programs in St. John’s, Newfoundland. Her background in the field of community capacity building with focus on early learning and complex needs of families using strengths- based holistic programs, along with education and training in education/adult education, horticulture and horticultural therapy inform her work.
