MCT Garden Club Hillwood Estates Tour September 2023
We all had one delightful day at Marjorie Merriweather Post’s Hillwood Estates! The gardens were lovely and we were so glad that the garden tour was in the morning as it did get a bit warm. We then enjoyed a delicious “tea” with all those yummy tea sandwiches and petit fours. It was such an informative tour of her mansion following lunch.
See below for photos from our tour.
Planning Tips
- It’s harvest time and also a good time to start taking stock of what worked well for you this season and what didn’t.
- Check out garden centers for end-of-summer bargains.
- Take photos and update your garden journal.
- Start shopping for spring bulbs.
- 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.

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/

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:
