Perlite is the perfect soil amendment for any serious gardener. Perlite helps improve drainage and aeration while also increasing air-filled porosity, allowing for an improved root system and bigger harvests. Perlite is a lightweight, volcanic rock that is heated to a high temperature and then popped like popcorn, forming small, white pieces of rock.
When added to soil, it helps to balance the pH level and reduce compaction, making it easier for the roots to spread and take in the nutrients they need. It also helps to improve aeration, drainage, and water-holding capacity, ensuring that your plants have the best chance to thrive. Perlite, you will have the perfect soil amendment for your garden.
Perlite is a lightweight granular material that’s white in color.
It looks and feels like little bits of polystyrene but is actually made from expanded volcanic glass, heated to 1000°C until it ‘pops’ (like popcorn) to many times its original size.
It’s lightweight, sterile, and easy to handle, and is long-lasting.
While it does also help retain some water, perlite is primarily used to aerate compost. It excellent for creating a free-draining potting compost for plants that need good drainage, such as cacti and succulents. It can also help create an airy compost for seedlings.
It is possible to grow most plants in perlite alone, although usually the finer grades and medium grades will work better and require less water.
Is too much perlite bad for plants? Perlite is for slowing down the tendency for the soil to compact and helps the soil to retain moisture. The soil provides the place for bacteria to flourish. Too much perlite and there isn’t enough soil to keep the bacteria going. They are what help the roots to take up nourishment.
Does perlite provide nutrients to plants? Chemical Characteristics—Perlite is neutral with a pH of 7.0–7.5, but it has no buffering capacity and contains no mineral nutrients.
Should I mix perlite with potting soil?
Perlite is often used in seed-starting and potting soil mixes because it keeps the soil loose, well aerated and well draining. To make your own soil mix, use 1 part perlite, 1 part loam and 1 part peat moss and mix well. In the garden, perlite can be scattered on top of the surface.
How much perlite do you mix with potting soil?
For container gardens, potted plants and raised beds, use up to 1/3 perlite per container. Succulents and orchids especially love perlite, and their potting soil can be mixed with half or even more perlite depending on the species.
