Used of perlite: SOIL CONDITIONING Where the native soil is heavy or sticky, gentle mixing of vermiculite up to one-half the volume of the soil is recommended. This creates air channels and allows the soil mix to breathe. Mixing vermiculite in flower and vegetable gardens or in potted plants will provide the necessary air to maintain vigorous plant growth. Where soils are sandy, mixing of vermiculite into the soil will allow the soilto hold water and air needed for growth. SEED GERMINATION Use vermiculite alone or mixed with soil,perlite or peat. Very little watering is required. More seeds germinate – faster germination too! Where vermiculite is mixed half and half with soil, peat, or composted pine bark, no additionalfeeding is required up to the time of transplanting. HOUSE PLANTS Vermiculite eliminates the problem of packed-down soil in flower pots. Mix half and half with soil, perlite, peat and/or composted pine bark. It provides excellent air and moisture control for house plants. Lightens and aerates soil. Roots can spread out through the pot. Less frequent watering is required.
