Cabbage planted in a garden

Fall cold crops are best if planted out of winter winds and in part to full sun. Transplants work well or you can plant seeds in early August directly in the soil but, understand soil temperature is the indicator of germination and they prefer cooler soil to do so. Cold crops that prefer cooler soil may not emerge for a time. Depending on how long summer heat and soil dryness persists, a later planting may be desirable when nights cools down and dew is abundant to hold soil moisture.

3 tips for fall planting:

  1. With fall crops being root crops make sure that your soil is mixed nicely to the depth of six inches. 
  1. Apply a fertilizer lower in Nitrogen higher in Phosphorous and Potassium to root crops and one higher in Nitrogen and slightly lower in Phosphorous and Potassium on leafy crops. Keep in mind micro-nutrients should in fall fertilizers. 
  1. Plant fast growers like lettuce weekly so you have it available for longer harvest. Stagger turnip plantings as they will grow for most of the winter.
