Cold Weather Crops
Lettuces, kales, broccolis, spinach - these are all cold weather crops. This means they are sweeter when overnight temperatures are 35-50 degrees. Plant them outdoors in April, or in March if you have a piece of plastic to throw over the plants on cold nights. The seeds won’t sprout for 11 or 12 days, and they will be cozy warm in the ground, so it’s ok if it is still freezing at night.
DO NOT START COLD WEATHER CROPS INSIDE. They do to make the transition to outside well.
