When it comes to giving your garden a boost, vermiculite will provide promising results. You may not have realized it, but you've surely seen this soil additive in potting mixes, coming in the form of shiny silver-like flakes.
Still, if you're new to the gardening game, you may not know what vermiculite for plants is and how to use it. For that reason, this blog will show you all there is to know about the soil additive, how beneficial it is, and whether it can be used for raised garden beds.
What Is Vermiculite For Plants?
Vermiculite for plants is a naturally occurring mineral, mined in various countries around the world, which is later exfoliated and treated with extreme heat and pressure. This results in a worm-like sterile product that is prone to expansion. Vermiculite is used in various industries, including gardening, given its non-toxic, pH neutral, and non-deteriorating properties.
The reason why so many gardeners use vermiculite for plants is because the mineral can absorb three to four times its water weight and also attracts various soil nutrients like calcium, magnesium, and potassium. This makes it great for propagating and potting plants that thrive in moist conditions.
Finally, vermiculite for gardening can be bought separately or it is found in potting soil mixes in different sizes. If you’re using it for germination, you should go for the smallest size; alternatively, the largest vermiculite flakes are generally used for improving soil aeration.

Luckily, vermiculite can hold and slowly release nutrients like potassium, calcium, and magnesium, providing a consistent food source for your plants.

Given its moisture-retaining qualities, vermiculite is ideal for seed starting and encouraging root cuttings to take hold. That said, if you're thinking of growing plants that may have seemed too challenging for your taste, this mineral can give you the assurance you need, resulting in a blooming and vibrant garden.
