18 Inch Tree Diaper

  • 18
This smart irrigation system keeps your trees watered all year with minimal effort. Simply install around your tree, cover with mulch, and provide an initial overnight soaking. Then enjoy maintenance-free watering for weeks, months, or even longer.

  • Can function without refilling with as little as 1" of rainwater, snow melt, or sprinkler irrigation per month thanks to water-absorbing pellets
  • Releases water slowly — and only when the ground is dryer than the TreeDiaper
  • Designed for large containers, saplings or small bushes
  • Maximizes water use and can lower water consumption by 50–80%
  • Promotes healthy root growth by providing a bed of hydrated soil 14" deep, encouraging roots to grow outward and establish the tree more quickly
  • Eliminates competing plant and weed growth around the root system with a built-in weed barrier top
  • Protects root system in extreme temperatures
  • Also available in a 24" size for bushes and trees up to 1.5" caliper and a 36" size for trees up to 3" caliper
