Vermiculite

Here are some of the horticultural uses of vermiculite:

1. Seed Starting: Vermiculite is a popular component in seed starting mixes. It helps to retain moisture around the seeds, providing a favorable environment for germination. The fine particles of vermiculite also provide good contact between seeds and the growing medium.
2. Soil Amendment: Vermiculite can be added to garden soil or potting mixes to improve their physical properties. It helps to loosen compacted soil, improve drainage, and enhance aeration. Vermiculite also acts as a sponge, holding moisture and nutrients near plant roots, promoting healthy growth.
3. Rooting Cuttings: Vermiculite is often used as a rooting medium for plant cuttings. Its moisture-retaining properties create a humid environment that encourages root development. The lightweight and sterile nature of vermiculite make it suitable for starting new plants from cuttings.
