Be aware, many of the warm seasoned
veggies in the stores are suffering from
the cold weather.  I saw several stores
today that had squash, pepper that the
 new growth was yellow.  Soil is just too
 cold to grow properly.

Soil planting will help but warmer soils
 is the key, or put water jugs, walls of
water or Remay cloth over the warm
season plants.
