While soilless potting mix is available at many garden centers and nurseries, you can also make your own soilless mix. A standard homemade soilless mix contains equal amounts of peat moss, perlite (and/or vermiculite), and sand. Bark can be used in lieu of sand, while coconut coir can replace peat moss.

How can I make my soil lightweight?

Moisten each ingredient, then thoroughly combine: one part vermiculite, one part compost, two parts loam or topsoil, three parts coarse perlite and three parts filler (decayed bark, shredded coconut fiber, peat moss or any combination). Expect to fertilize regularly and to replace the mixture every few years.

Is soil less mix good?

A soilless mix provides a cleaner medium and gives you more control. 1 Besides being free of pests and diseases and other contaminants, you can blend in additional ingredients for preferred drainage, water retention, nutrition, and airspace.
