Did you know that most potting soils are made of organic matter like peat or coconut coir? They also have perlite or vermiculite to help with drainage and keeping moisture. These additives are key for healthy plant growth and better soil structure. But how do you know which works better: perlite vs. vermiculite?
Perlite and vermiculite come from volcanic rocks. They do similar jobs but in different ways. This makes them good for different gardening needs.
Perlite is a light, volcanic glass that gets up to 20 times bigger when heated. It’s great for potting mixes and seed trays. It lets air and water move through, helping roots grow well.
Vermiculite, another volcanic glass, is a moisture and nutrient keeper. It makes soil better, reduces packing, and helps seeds and plants grow.
When picking between perlite vs. vermiculite, think about what you need for your garden. A mix of both offers the best of both worlds. It’s good for plants in pots, raised beds, or in the ground. Knowing about these soil helpers can make your garden better for your plants.
Key Takeaways
