Extend Your Grow Bed

  • This extension kit adds 3′ to the length of our Grow Bed
  • Ideal for small-space kitchen gardens
  • How much soil? Use the Soil Calculator to figure out how much you need for this raised bed

A Grow Bed is the most efficient garden area you’ll ever tend, with black plastic sides that absorb heat to warm soil early in the season, then help retain moisture all summer long. These two-sided extension kits double the growing space of our popular grow beds by creating a raised bed that is the same width but twice as long.

Product Details

  • 100% recycled plastic
  • Each kit contains 2 sides and a hardware pack
  • Dimensions: 38-3/4″ L x 18″ W x 10″ H
  • Easy assembly; requires a drill
  • Gardener’s Supply Exclusive
