Brassicas for Early Spring Planting

Brassicas are heavy feeders. They require fertile soils in a pH range of 6.5-7.5. Be sure to keep them watered throughout the growing period. Brassicas prefer cooler growing temperatures, between 55°-75°F (13°-24°C), with the optimum being 60°-70°F (16°-21°C), but they will produce good crops under warmer, summer conditions.

If you start your plants from seeds, you'll want to start them about six weeks before the last frost. The maturity dates for these vegetables are usually from transplant, not seed. When direct sowing, add 14 days. So, whether you start your own seeds or buy plants, you'll want to plan accordingly. I usually start mine in soil blocks so there is no transplant shock.





Cabbage
For spring planting use early and midseason varieties. Choices include regular or savoyed, red, and mini cabbages.


Broccoli
Choose a variety developed for spring planting, such as Early Dividend, or a heat-tolerant variety, such as Gypsy or Green Magic. Harvest before the flower buds open and cool immediately. Most varieties will produce side shoots after the main head is cut. Harvesting the side shoots regularly will encourage continued production.


Cauliflower
When choosing a cauliflower variety, make sure to choose one specifically for spring planting. For fun, try growing some green spiraled, purple, or orange heads.

Brussels sprouts will do better as a fall crop because their flavor is enhanced after a frost.


Using floating row covers can add protection from unexpected late frosts, as well as protection from insects, such as cabbage moths. To avoid cutworms, use collars around the stems or sprinkle diatomaceous earth around the base of each plant.
