Cool Season Veggies

Late March is a great time to start planting cool season vegetables. Cool season crops prefer cool daytime temperatures of 60 to 80 degrees, and down to 40 degrees at night.

Semi-Hardy vegetables such as beets, carrots, cauliflower, parsley, parsnips, potatoes and Swiss chard are less tolerant of a frost, and may need some additional protection. Using mulch, Season Extenders and covering with row covers will help protect veggies from low temperatures. The most cold-hardy, such as broccoli, cabbage, kohlrabi, onions, lettuce, peas, radish, spinach and turnips, can withstand a frost.

Cool-season crops will stop producing when temperatures are high in the summertime, but keep in mind you can plant another round of crops in late summer for a fall harvest!

We have an extensive selection of cool season veggie seeds from great companies like Beauty Beyond BeliefBotanical InterestsHigh Mowing Organic SeedsRenee’s GardenSeed Savers Exchange, and Folks Farm & Seed.

Cool season starters like broccoli, cauliflower, cabbage, and various greens will also be available in our greenhouse later in the month of March.
