Clever Gardening Technique

Use Plastic Sheeting or Jugs as Slight Frost Protection
You can help seeds germinate -- and early seedlings grow -- outdoors after watering them in by covering the seed or seedling beds or trays with clear plastic sheeting or clear plastic milk or water jugs with their caps removed and their bottoms cut off. Although the plastic doesn't alleviate very much of the chill from cold nights, it does help the soil absorb daytime warmth, and it lessens evaporation. This provides the seeds with a more comfortable environment in which to sprout and develop. When the seedlings are one inch tall, remove the plastic sheeting during the warmer daylight hours to begin acclimating them to the coolness, but re-cover them at night. After a week or two, remove it completely. Remove the jugs when the foliage begins to crowd the jug, or when night temperatures are above 50 degrees.
