First, make an impression in the seed starting mix and place a seed in each impression. Next, use vermiculite to lightly dust or cover the Seeds. This technique has several benefits. For instance, it will prevent the growth of algae on the surface of the seed starting mix, it will reduce or eliminate the presence of fungus gnats which can harm seedlings. It will also keep the Seeds from being too wet during the germination process. Vermiculite is an excellent addition to pots of soil, whether that be in outdoor containers or in houseplants. Mixing some vermiculite into your potting soil will improve aeration and moisture retention, resulting in a healthier root system that is better able to spread out and absorb nutrients.
