Being in a valley in East Tennessee, we here at GreenStalk experience some pleasantly mild winters. While we don’t always have a white Christmas, it does make for some fairly decent fall planting. Generally, leafy greens or root vegetables are the best options for planting in cool weather and will be great choices for a spring or fall harvest. Hardy vegetables usually do the best in temperatures ranging from 25 to 28 degrees F versus semi-hardy vegetables which can tolerate light frosts from 29 to 32 degrees F. Usually you can plant any variation of these vegetables together as long as they stay within their respective temperature range however, there are certain companions that will make your harvest thrive even more. On the other hand, there are some exceptions to this list such as: don’t mix lettuce with parsley and do not plant mustard, radishes or root vegetables near turnips. Lastly, be sure to plant late enough into the spring season in order to avoid bolting of plants and early enough in the fall to avoid frost.
Some varieties are better for spring planting and others for fall. Check your seed packet descriptions for info on how to make sure your seeds will germinate and thrive. Here’s a basic chart to use when growing in your GreenStalk or when growing a variety of vegetable plants:
Hardy: broccoli, cabbage, kale, kohlrabi, leeks, spinach, turnips
Semi-Hardy: beets, carrots, endive, lettuce, mustard, parsley, potatoes, swiss chard
