Vermiculite is a naturally occurring mineral formed from hydrated magnesium aluminium silicate. When heated, it expands into lightweight, absorbent granules that improve soil aeration and moisture retention. It is chemically inert and sterile and does not degrade over time, making it an excellent choice for seed sowing, potting mixes, and soil conditioning.
No, vermiculite is entirely non-toxic and safe to handle. It does not contain harmful chemicals and is often used in horticulture for seed starting and soil improvement. To minimise dust when handling it, it’s best to use it in a well-ventilated area and wear gloves if you have sensitive skin.
Vermiculite is widely used in gardening to improve soil aeration, water retention, and drainage. It is commonly mixed with compost for seed starting, helping to create a light, moisture-retentive growing medium. It also reduces soil compaction, making it easier for roots to spread.
In potting mixes, vermiculite for plants helps prevent water from draining too quickly while keeping the soil well-aerated. It can also be sprinkled over sown seeds to maintain moisture during germination. Unlike perlite, which primarily improves drainage, vermiculite holds more water, making it particularly useful for moisture-loving plants and young seedlings.
