Season Extenders & Plant Aids (50 Products)

Lengthen the growing season for your favorite plants and vegetables using a season extender. Such extenders can be greenhouses, covers, or frost blankets. Greenhouses offer storage for your young or fragile plants, and the glazing on their sides captures the heat of the sun for a warm enclosure. Frost blankets, covers, and plant insulators surround or cover young plants, protecting them from cool air in the beginning of the growing season. Lighted tables create spaces for plants in your home, and specifically designed trays help plants flourish. Find all you need for a long growing season in our Season Extenders department.
