Perlite is used in potting soil mixes because it modifies the structure of soil and improves aeration by keeping it loose and preventing compaction. 

This lightweight Perlite provides superb aeration and moisture retention when mixed in with other soil materials. Perlite supports root growth and retains moisture, air, and nutrients.

Perlite is also an excellent rooting medium for cuttings. Roots formed in perlite are much stronger than those formed in water because perlite allows oxygen to reach the roots as they develop, enabling the roots to adapt more readily to a soil environment.

Vermiculite It is very lightweight and mixes easily with other mediums. When added to potting mixes it increases water and nutrient retention and aerates the soil, resulting in healthier, more robust plants. Perlite may also be found in potting soils, but vermiculite is far superior for water retention. Vermiculite, although less aerating than perlite, is the amendment of choice for water-loving plants.

The earthworm’s special digestive process transforms organic material into a fantastic soil supplement that plants simply love. Combine G&B ORGANICS WORM-GRO with your native soil or use it as an effective “worm tea” to fertilize a variety of plants, flowers, vegetables and even lawns. By mixing WORM-GO into your soil at the drip line, you’ll be helping your plants resist disease and pests while increasing beneficial microbe activity that creates a great soil environment in-ground or in-containers.
