New & Exclusive | Cold Frame Gives You a Jump on the Growing Season

  • Shelter seedlings from chilly spring weather
  • Start gardening earlier and grow later in fall
  • Protects plants from insects and animals, too

This convenient cold frame provides a sheltered place to harden off seedlings, and protects plants from unpredictable spring weather for faster growth and an earlier harvest. The cover protects plants from harsh wind and chilly temperatures, as well as insects and other pests. It also prevents indoor-grown seedlings from getting sunburned as they acclimate to the outdoors. Adjustable screened vents promote air circulation and allow excess heat to escape on sunny days. Also handy for extending the growing season later into fall. 4' square x 27-1/2" high; sized so it can also be used over a 4' 4' raised bed.

  • Assembly required
  • Powder-coated steel frame; reinforced PVC cover
  • 48" sq x 27-1/2" H
  • Imported
  • Gardener's Supply Exclusive

Cold Frame doubts

      Best Uses

        I have raised beds that this product fits perfectly.
        The separate zippered ends allow easy access and the separate netting zipper provides flexibility for temperature control.
        I had reservations about spending that much money; now, I plan to purchase either 1 or 3 more for next season.

        Jump Start the Garden

          • Early Spring Gardening
          • Late-fall Gardening

          This cold frame is one of many products I test here at Gardener's Supply. I tested the 4x4 Cold Frame last year, starting in late April. I planted seeds in a 4x4 raised bed and secured the cold frame to the top. From the photo you can see that there was still snow on the ground. By mid-June, the cold frame was off and the bed was bursting with life. I love all the different textures and shades of green in such a compact space.

          I planted many early season crops, including Red Cardinal spinach, Wildfire lettuce mix, red Russian kale, Swiss chard and bok choy.

          It's amazing to me that all of this life/sustenance/nutrition thrives in 16 square feet — and it was planted while there was still snow on the ground.
