Back to the Roots 100% Organic Perlite | Made in The USA | Premium Nutrition for Indoor and Outdoor Plants

I usually mix some perlite and pine bark into the potting mix they sell at the big box stores to improve drainage and aeration of the soil. You don't need too much of either - less than 10% of the total amount of soil. My many house plants are happy.

This is high-quality perlite. The pieces are not too big, and not too small, and it was a great deal.

Great on plants and I always use this when I transplant my plants into larger pots and also in the winter time. Every winter, I sprinkle just a small amount on top of the soil in each of my plants, to protect any roots that may be exposed and this helps when watering too, it seems to keep the water in place and gets slowly released down into the soil over due time. If that makes any sense. My plants do better when I sprinkle this but ...not a lot, just a little bit at a time.

This is exactly what I needed for the bottom of my planters for drainage.

better than expected.
