Hello Friends, Neighbors, Fellow Gardeners,
Happy July! Hope you are staying cool and enjoying watching your flower and vegetable gardens grow! Don’t forget to support our local farmers by visiting our local farmer’s markets and local farms! Make sure you have your gardens taken care of when you plan your summer trips. 🌞🌼 Here are some garden tips, educational opportunities, and videos for July. This includes some events from U.S. Botanic Garden, Master Gardeners of Montgomery County, and Maryland Gardens. A lot of gardening events are announced on Facebook and we share them on our Facebook page as well as on our mctgardenclub.org website. Some upcoming events include IPM for Backyard and Community Vegetable and Fruit Growing webinar, Septic Field Landscaping webinar, Woodland & Wildlife Wednesday, Montgomery County Master Gardener Virtual Question & Answer Program, Farm Tour 2022, and more! Have some spare rocks you can donate? We need rocks for the Miller Fall entrance! See below for details.
We’ve been busy gardening!
We’ve been busy gardening and maintaining the Mill Creek Towne entrances (Miller Fall Road and Roslyn Avenue) this summer. We appreciate your donations to help us keep going! To learn how you can make a donation to help us, please visit our website. Stay tuned for announcements for our community events this fall and next spring!
Rocks Needed for Miller Fall Entrance!
On Miller Fall Road, as you exit Mill Creek Towne to Muncaster Mill Rd, the bed on the right is being eroded by rains. To prevent further erosion we need 3 in. – 5 in. rocks to channel runoff as well as placing some under the opening in the wall which is breaking down. Let us know if you can help! Thanks!

Planning Tips

- Take photos and update your garden journal.
- 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 2022 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.

Home & Garden Information Center Tips and Tasks
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:
