When compared to perlite, vermiculite holds more water and nutrients than perlite and is ideal for most plants, especially those that are less tolerant to underwatering. While vermiculite does provide aeration, it doesn't aerate as well as perlite. Vermiculite is also believed to help plants take up nutrients in the soil more easily. Use up to 50 percent vermiculite in your potting mix. Vermiculite is very popular with container gardeners and is a great additive for planters or indoor plant pots.
