There are also clinics three days per week at Brookside Gardens. The busiest season is April through September, but some clinics are open year-round. Bring your plant samples and questions to one of these locations in Montgomery County, MD (see link below to find a location near you):

Montgomery County MD Food and Beverage Guide
The 2024 MoCo Food & Beverage Guide is here! The Guide from the Montgomery County Food Council is available online – delicious baked goods, prepared foods, condiments and more. The craft beverage list grows each year and find two dozen local and amazing farms:

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
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:

5 Million Trees Initiative
Maryland’s goal is to plant and maintain 5 million native trees by 2031. There are various ways you can get involved – plant trees and register them — or volunteer! A number of tree-planting assistance programs are available at the municipal, county, and state levels.
THIS is the SUPERPOWER of YOUR KEYSTONE NATIVE PLANTS.
- No exotic plant could ever achieve this.
- Want butterflies? Feed the caterpillars with keystone plants!
- Exotic plants will never support as many different species of caterpillars as the Keystone Natives can.
- Find your keystone native plants here by zip code.
If your zip code doesn’t give you enough information try zip codes of the nearest larger town or city. LINK: https://www.nwf.org/NativePlantFinder/
