Aldermere Farm welcomes interested gardeners and would-be gardeners to two workshops in April as part of its Grow Your Own Food series.

Jed Beach will run “Getting Your Garden Soil Into Shape” on Thursday, April 8 at 6 p.m. A healthy, living soil fosters plants that are tastier, more productive, and more resistant to diseases and pests. Many garden problems can be solved with good soil management. In the talk, Beach will cover the basic soil types of Knox County, how to collect and analyze soil tests, the wonders of compost and organic matter, the miracle of microorganisms, and an overview of the key nutrients and minerals needed for plant growth (and, more importantly, how they are made available to plants). The workshop will end with a soils troubleshooting roundtable.

Sharon Stone’s presentation on heirloom tomatoes will be held Saturday, April 10 at 10 a.m. at Aldermere Farm. Stone has been growing vegetables in West Rockport since 1979. About 15 years ago, she started to discover the open pollinated and heirloom varieties available in tomatoes and peppers. Most years, she starts (and grows) between 75 and 100 varieties of tomatoes and 15 or so types of peppers. Last fall, 12 varieties of garlic went into raised beds to become part of jarred salsa. Stone’s presentation will focus on heirloom tomatoes and their various traits, habits and uses.

Both presentations are free and open to the public, but registration is required because space is limited. For more information or to register, call 236-2739 or e-mail jbeach@mcht.org.
