#LocalIsTheNewNormal #BuyLocal
- Support Our Local Farmers – Join a CSA and have fresh local produce delivered to you!
- Visit a local farmers’ market.
“During shelter-in-place, farmers’ markets remain open as an essential service, providing a vital source of fresh fruits and vegetables and food staples for our communities in a spacious, open-air setting. But our community and our farmers’ markets could be jeopardized if we don’t each do our part to stay safe during this public healthy crisis.
In good times, farmers’ markets have been places to gather and converse, however, now is the time to follow public health and safety advisories and resist the urge to linger and socialize. We all have a critical role to play in preventing the spread of COVID-19.”

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:
