Early Plantings Must Be Cold Crops

Is it cold crops or cole crops? Both terms work, actually. Let me explain.

First of all it’s the beginning of Spring. The Northern Hemisphere of the Earth is waking up slowly from its long winter nap. Birds and animals of all sorts have been wandering near and far to find mates as evidenced by the increasing roadkill we see at this time of year. I think the order is skunks first, then opossums, and raccoons judging by the carnage. 🙁

In the garden Spring starts a little slower than in the animal world. However, there are a number of plants that can take the cold and even grow in low temperatures.

Lettuce and onions have already been planted in our vegetable garden, but they’re not without protection from freezing temperatures. Old sheets to the rescue!

Cold crops would be described as all the plants that do well in the cold. How cold is cold? Just think Spring or Autumn temperatures at the ends of the growing season.

Cole crops are plants who are members of the Mustard Family, Cruciferae, now known as Brassicaceae.

The word cole derives from a Latin word caulis which means stem or stalk. A few of the cole crops even have names derived from the same term: cauliflower, collards, broccoli, kohlrabi, kale. All these guys excel at growing in cool temperatures.

In general leaf and root crops may do ok in the cold, but fruiting crops will have to wait for the warmer weather of summer. Tomatoes and peppers are example plants that need more heat to develop their fruits.

Here’s a list of cold crops separated into types of crops — leaves, roots, coles, and flowers:

LEAVES/Leaf Crops
lettuces
spinach
swiss chard
fava bean greens
arugula
parsley

ROOTS/Root Crops
onions
shallots
leeks
beets
carrots
peas
potatoes

COLES/Cole Crops
cabbage
broccoli
cauliflower
brussel sprouts
kohlrabi
turnip
parsnip
kale
collards
mustard greens
bok choi
Chinese cabbage
radish
horseradish
cress
watercress

FLOWERS/Flower Crops
pansy
calendula
alyssum (also in the mustard family!)

Any of the above should be able to be planted early, as in before the average last frost date for your area, provided that they are afforded some type of protection from late Winter freezing weather. At the extreme, for PA anyway, we’ve overwintered lettuce using sheets for protection.

So far, we can add parsley and alyssum to our planted list along with lettuce and onions. Garlic has overwintered and is already growing big and tall.

Next to be planted will be potatoes and peas!
