Planning Tips

  • Check out garden centers for discounted house plants.
  • Take photos and update your garden journal.
  • Inspect your garden hose for leaks an tighten all connections.
  • As the heat and humidity move in, take it easy by working in the morning or early evening to avoid intense sun and humidity. Leave the big projects for this fall. For now, just concentrate on maintaining the beds you’ve already established and nurturing new plantings.
  • Plan for 2023 with these Free resources: Landscaping with Native Plants by the Maryland Native Plant Society, Plant Invaders of Mid-Atlantic Natural Areas by the National Park Service, Master Gardeners of Northern Virginia Reading Room.

Support Our Local Farmers – Join a CSA and have fresh local produce delivered to you!

CSAs are seeing record numbers of subscribers http://ow.ly/eiQT50zD5lW – find your farmer here: http://ow.ly/jbO250zD56M

Montgomery County Community Supported Agriculture (CSA)

CSAs can take many forms, but essentially they are community supported farms in which members contribute to farming projects, usually by way of membership fees, in exchange for fresh, local produce. The concept came to the United States from Europe in the 1980s.  They are a great way to take advantage of fresh, locally grown fruit, vegetables, herbs, and more while supporting nearby farms. Each one is different, some offer pickup locations in urban areas, some offer only farm-based pickups.

There are multiple CSAs located around the County offering a wide variety of products. CSAs begin taking sign-ups for spring and summer seasons in the early part of the year, and they tend to fill up FAST! Know of another CSA not on our list? Let us know! Montgomery Countryside Alliance also maintains a list:

June 15 – Native Pollinators of the Mid-Atlantic
Speaker:  Samantha Nestory

“Pollinator” is a term that has gained massive popularity over the past couple of decades as our knowledge and understanding of our ecosystems have grown. Unfortunately, many people only associate this term with popular pollinators, such as European honeybees and butterflies – but there’s so much more to the world of pollinators. Join us as we learn about native pollinators that don’t get the spotlight and how we can support these incredible movers and shakers in our gardens and landscapes.

Samantha Nestory (she/her) is the engagement manager and naturalist at Stoneleigh: a natural garden in Villanova. In her position, she develops educational programming, coordinates public events, and manages the volunteer program. Previously, she worked as a horticulturist at Stoneleigh for nearly four years. She is passionate about native plants, ecological gardening, and insect conservation, and she is strongly committed to educating the public about these important issues.

June 22 – Horticultural Therapy: Nurturing Plants Nurtures People

Speaker: Irene Barber

Have you ever heard of Horticultural Therapy or Therapeutic Horticulture? Registered Horticultural Therapist and Adult Education Program Manager at Coastal Maine Botanical Gardens, Irene Brady Barber, will explain about the value and practice of Horticultural Therapy through the lens of the HT program offered in the Lerner Garden of the Five Senses in Boothbay, Maine. Just as art therapy, music therapy and other applied creative therapies are complimentary modalities to traditional healthcare services, horticultural therapy offers people of all abilities the chance to nurture themselves and reach personal goals, such as physical rehabilitation, mental health support, cognitive restoration and so much more.

Motivated by and deeply focused on connecting people to plants, Irene Brady Barber, horticulturist, landscape designer and Registered Horticultural Therapist, manages the Adult Education Program and the Horticultural Therapy Program for Coastal Maine Botanical Gardens in Boothbay, Maine.

June 29 – Managing Trees and Public Spaces for Wildlife  
Speaker: Marne Titchenell 

The World Health Organization reports that green spaces in urban areas are essential resources necessary for healthy and sustainable living environments. They allow urban dwellers to connect with nature, which provides measurable physical and psychological benefits. For wildlife, the rate at which natural habitats are being conserved is declining, and there is great potential to provide valuable resources within city and community green spaces. This talk will discuss strategies and ideas for managing trees in public spaces (i.e. parks, recreation spaces, residential areas) for wildlife. Specifically, we will talk about how to promote habitat for birds, bats, pollinators, and other wildlife.

Marne Titchenell is the Extension Wildlife Program Director, with the Ohio State University. She works within the College of Food, Agricultural, and Environmental Sciences in the School of Environment and Natural Resources. She provides a variety of educational programs, workshops, conferences, and publications centered on wildlife ecology and biology, habitat management for wildlife, and managing nuisance wildlife species.
