VERMICULITE

If you’re looking for an additive to improve the quality of your soil, or even entirely replace the soil, then vermiculite is an attractive option. It is commonly used in soil mixes, as well as by professional gardeners and nursery workers to improve seed germination success and encourage rapid root growth in cuttings.

It can also be invaluable in preventing plants from being over watered and succumbing to root rot, as it has impressive moisture retention properties that release water in line with the plant's needs.
