Vermiculite is a lightweight, airy mineral that can absorb large amounts of water and release it gradually. This helps the growing medium retain moisture for longer while allowing sufficient air to reach the roots. Vermiculite can also retain nutrients and gradually make them available to plants.
Thanks to its fine structure, vermiculite is particularly suitable for germinating seeds and growing young seedlings. It can be used on its own as a seed-starting medium or as a covering layer over freshly sown seeds. This helps keep the surface moist for longer and prevents the seeds from drying out during germination. Its loose structure also makes it easier to transplant young seedlings without damaging their delicate roots.
Vermiculite can also be added to potting soil to improve moisture retention. This is particularly beneficial for plants that require a consistently moist growing medium. For example, mix 1 part vermiculite with 3 parts potting soil.
Moisten the vermiculite before use, but avoid soaking it completely. An easy way to do this is to submerge a sieve filled with vermiculite in water and then allow it to drain thoroughly. When using vermiculite on its own as a seed-starting medium, place a layer a few centimetres deep in a seed tray and sow the seeds in it. Cover the tray to maintain high humidity during germination.
