Vermiculite is almost magical in its abilities — it prevents root rot while providing essential moisture. It can replace soil in hydroponics and can be used to germinate seeds. Different grade and size vermiculite differ with each purpose. Here is a list of the best vermiculite online to help you choose the one fit for your garden.
Vermiculite is indispensable. It can be used to germinate seeds because it holds water that the seed can absorb slowly. It prevents compact soil by absorbing excess water and providing aeration. When you replace soil with vermiculite, you’re also allowing the plant to absorb other nutrients like calcium and ammonium for faster growth. You can also mix vermiculite into soil to prevent root rot and drying out. Let’s check out our top picks for the best vermiculite.
