Horticultural Bonsai Pumice Soil Amendment (2 LB), Supplement for Bonsai and Cactus Indoor Plants

The product is great, which is the reason for the 5 star, but Amazon needs to do better with packaging. They did not double seal it before shipping. It ended up exploding inside and stones were everywhere leaving a mess.

I definitely will purchase this again, I make my own substrate for my plants, I usually use horticulture grade perlite-but I thought I would give this a try, I definitely like it

I do believe this stuff is saving my cactus & succulents lives!! I am new at fiddling around with plants, in particular cactus & succulents. They were all looking very sad until I added about 2 parts of this stuff with 1 part regular soil & 1 part gravel, lava rocks or perlite. And BAM! My plants r doing beautifully. I just wish it wasn't so expensive cuz I can see where over time this is gonna be a spot to have to add it to my regular budget calendar month after month! Otherwise good stuff !

The chunks are a bit smaller than I was expecting and I thought the bag was going to be slightly bigger… but it works great for a soil amendment for my plants!

This was the fourth or fifth time I've purchased this pumice. It works great for succulents. I do wish the bags were bigger for the price. I always pour the pumice into a strainer and rinse them off then lay flat on paper towels to dry before mixing with my soil. It really makes a difference and gets rid of all the "dust". I will definitely continue purchasing this pumice in the future.

This is the first time I've ever grown Plumeria and I read everything I could about what they needed to root and what makes them happy. This product worked great with the phosphorous that was also recommended and the plants quickly began to take shape and leaves began to spread. In just 3 months, the transformation was fantastic.

Product might fill a 1 gallon pot half full. Rock is ⅛ in size. Product is great for what it is. 3 stars because I can get better quality in ⅜ size for the same price and its 8 quart bag, 2 gallons. Product is fine. Just not what I thought I was getting. My mistake.

great size for indoor plants, perfect for homemade PON.
