Clay pellets are a soilless growing medium made from small, hard-fired clay balls. The pellets are usually between .03 and .08 inches around. The firing process causes the clay to expand creating a porous medium. Clay pellets are most commonly used in hydroponics and for orchids and other plants that require a soilless growing medium. Use clay pellets to increase drainage in potting soil mixes for houseplants and other container grown plants and trees.
Combine 1 part clay pellets with 9 parts standard, good quality potting soil in a bucket.
Mix the pellets and the potting soil together thoroughly using your hands on a long stir stick or spoon.
Use the clay pellet and potting soil mixture for all your container grown plants that require good drainage.
Spread a 1-inch layer of clay pellets over the bottom of the planting pot before adding potting soil to increase drainage.
