- Vermiculite interacts with potassium, calcium and magnesium in your soil. It also help to raise the pH slightly of your plants even though it’s a neutral pH of 7.0.
- When water is added to vermiculite, the flakes expand into a worm-like shape and act like an absorbing sponge.
- Vermiculite is best used for plants that require soil to stay damp and not dry out. For plants that love water, using vermiculite or mixing a healthy scoop of it into your potting soil is the way to go. It can absorb 3 to 4 times its volume when water is added, making your pots a little bit on the heavy side.
- Since vermiculite acts like a sponge and absorbs more water than perlite, it doesn’t aerate the soil as well. This means less oxygen for plant roots. If you use it when growing plants that don’t need damp soil, you might find your plants suffering from root rot.
