Use Growstones Soil Amendment in containers and gardens:

  • Potting Mix: Use Growstones 1:3 with peat moss, or coir (coco-peat) as part of your potting mix, to help retain moisture and improve drainage.

  • Gardens: Tilled into the soil in flower and garden beds, Growstones will help enhance drainage and reduce water requirements.

  • Trees and shrubs: Use Growstones in combination with a three- to four-inch layer of organic mulch, such as bark or wood chips, in planting beds, or around trees and shrubs to hold in moisture and limit weed growth.
