Upcoming Events

Through May 23
Gardeners already knows the physical and emotional benefits of getting a little dirty and watching something beautiful grow.  Research has backed this up, showing that spending time in the garden improves mood, lowers blood pressure, and reduces stress.  All of which means that quarantine is a great time to get planting, when many of us could use some nurturing for our bodies and minds.

We have a great local option to make your spring plant shopping safer and easier:  Locust Grove Nature Center’s ONLINE Spring Native Plant Sale !  It won’t be held in person this year, but they have come up with an exciting way to offer plants to all of you who are still gardening while staying close to home.

​Visit Locust Grove’s Native Plant Sale webpage for Inventory, Ordering, Payment, and Pick-Up details.

For pick up on Saturday, May 23, orders must be received and paid for by 5pm on Thursday, May 21.  Inventory is limited.

To find out more about Montgomery Parks’ quarantine policies, you can visit their COVID-19 webpage.

Stormdrain Labelling

Stormdrain labelling is an easy and effective method of educating neighbors about watershed stewardship that will protect Cabin John Creek, the Potomac River, and the Chesapeake Bay.  Volunteering for a stormdrain labeling project is a fun way to give back to the community and help protect our natural world.
