Ahh, spring, when a gardener’s thoughts turn to sowing the first seeds of the year: cool-season vegetables.

What are cool-season vegetables? They are plants perfect for springtime weather. They can withstand light frosts and nighttime temperatures above 40 degrees, but hot temperatures (above 80 degrees) will cause them to go to seed and taste bitter.

Cool-Season Crops

Plant cool-season crops two to four weeks before the last frost, around May 15 in the North and April 23 in the South. (Some superstitious-minded folks always plant on St. Patrick’s Day.)

You may plant radishes, lettuces, spinach, beets and any kind of peas and carrots from seed simply by reading the package directions. For broccoli, cauliflower, cabbage and onions, just buy plants to pop in the ground. Other green veggies to try include parsnips, turnips, Swiss chard, kale and collards.

Warm-Season Crops

As the cool season ends, reuse your garden space by planting warm-season vegetables such as cucumbers, tomatoes and squash. When autumn arrives, it will provide the right temperatures to plant a fall crop of cool-season veggies in the same space.
