What is Perlite in Potting Soil

What is Perlite in Potting Soil

Perlite, also known as Kieserite or Trona, is a lightweight volcanic glass heated to 1,600 degrees Fahrenheit. When it pops and expands at such high temperatures, it becomes incredibly thin but hard like a rock! This material weighs less than 5 pounds per cubic foot- making for some cool construction projects in your home. The superheated perlite is a unique type of volcanic rock that has many tiny cells on its surface. When water comes in contact with these particles, they absorb it without impeding diffusion with their pores or openings, making it an excellent material for facilitating plant roots to get ample moisture.

While perlite and vermiculite are excellent for adding extra moisture to poor drainage soil, they differ. Perlite is more porous compared to vermiculite and allows water to drain with ease while retaining moisture. It is perfect if you’re looking at planting cacti or other plants that need moist media but don’t grow well with wet roots.

When growing plants in perlite, you need to be aware of the potential for fluoride burn. It can cause brown tips on houseplants and reduce their water-retention capabilities if they are not misted before or during use (which also reduces dust). However, this low-fiding material offers higher humidity levels than vermiculite due to its large surface area, which helps with moisture retention too.

Perlite is the go-to soil for those who want to grow plants in containers. It improves aeration and modifies your dirt’s structure, making it loose enough that you won’t have any compaction or drainage issues, even if you use an empty pot! A premium mix of one part loam mixed with either peat moss or perlite will work best when starting on this type of journey so as not to fill up all cup size spaces available at once – remember there are always more pots coming soon after!

Perlite is a great medium for rooting cuttings, and it does so much more than just soaking up water. Plant your new plants in perlite with their ends sticking out of the ground about 1 inch from the soil surface. Place an air-filled bag over them to keep everything insulated from direct sunlight while you wait two or three weeks before planting outside after checking that roots have formed. Once the roots are 0.5-1 inch long, you can plant them in your garden.
