Customer Review: I’ve been mixing my own soils lately for my expanding potted empire. Everything from berries, fruit trees, citrus trees, decorative house and carnivorous plants. This is the sweet spot for price value. I was tickled when I opened the box and this giant bag was inside. I thought 8 quarts was pretty big. This is supersize me for only a couple dollars more! The perlite is pretty uniform, smaller in size. Perfect for making well drawing soil. I like the large very large size for big outdoor containers.No fertilizer is added to this (Unlike Miracle Grow ) if that is pertinent to your needs.
Customer Review: Product was fine but actually found a lot cheaper at my local garden nursery. However, beware, I pulled the bag out of the box and next thing I knew all of my product fell out of the bottom of the cheap plastic bag onto my yard. I looked at the bottom for the hole and it became apparent that the bag never had a sealed bottom. It was just open ended. What???

Customer Reviews
Customer Review: I have kept orchids indoors for many years and have great success with them. They bloom at least once a year, some twice. Store-bought orchids will be content in their cheap plastic growers pots for a while, and you should not transplant them while blooming. But soon, if they like their location and conditions, those roots will grow and crowd the pot, also retaining too much moisture. Your orchid leaves will not be the dark lustrous green they are supposed to be. Then you know it’s time to transplant but be careful! Sterilize your tools, be gentle and trim off the dead roots. As a matter of practice, I will pour enough water into the repotted plants so I know all the new soil is wet, let it thoroughly drain… then resuming a sparse watering schedule. My orchids are healthy and have lived quite a long time with proper care. The soil is easy to scoop by hand, you don’t need a spade. The soil also smells clean and is just the right particular size to tuck into the roots but prevent compaction. I like the ziplock seal, to keep for future use without the risk of contamination. Best wishes and enjoy your lovely orchids!
Customer Review: This orchid mix has put life back into my phalaenopsis! I rescued it from a family member who was unable to take good care of her plants and was unsure if the orchid would make it. The bark pieces are on the larger side, which leaves plenty of room for the extra air that’s needed. They have a nice smell as well! Overall effective mix and highly recommend 👍

Customer Reviews
Customer Review: This stuff is great. I wish I knew of this coconut derived soil a long time ago for my house plants. But the awesome part is that it could be dehydrated, compressed into a brick, packaged and shipped like that. It saves quite a bit of weight from needing to be transported.Some of the reviews (more so on some other brands) mention issues with reconstituting the bricks into a full amount of soil. I had none of these problems, and it was remarkably simple to do. I followed the directions, measured the water out and made sure to use warm (filtered) water. The brick instantly sprang to life once I poured the water on it (I used a 5 gallon bucket for one brick and that seemed just right). It took no further work on my part, the brick grew and separated out perfectly until it was just all fluffy soil. No dehydrated brick chunks or excess water remained.I’m definitely ordering more for other potting I need to do.
Customer Review: I have used Burpee seed starting products before, and always found them to be high quality. This was the first time using the Burpee Organic Coconut Coir Concentrated Seed Starting Mix, 16 Quart, but it won’t be my last! It is now my favorite seed starting medium. It arrives as a dehydrated block, wrapped in a thin plastic. I was suspicious of how it would absorb the water and rehydrate, as I’ve found highly dehydrated products challenging to rehydrate quickly. However, I was impressed with how easy it was to fully rehydrate this starting mix. I added it to a bucket, added the suggested amount of water and within just a few minutes the water was absorbed and the seed mix was rehydrated. I was able to have my seeds sown and ready to germinate within an hour of the package arriving at my door!My seeds germinated well, and have gone on to produce high-quality seedlings.I didn’t use all the mix in one go, once rehydrated it expanded, and there was more than I needed for my trays. I stored the bucket in my garage until I needed it again a few weeks later. The water had evaporated from the mix, but I was able to add more water and quickly be ready to sow more seeds.I will be ordering more once this has run out. I highly recommend the seller and the product.

Customer Review: This is a nice little inexpensive potting mat. It is small enough I can use it inside but big enough for room to work and contain the mess. The corners snap up and back down easily, making it easy to use, then fold back up for storage – it seems sturdy. The surface is waterproof and smooth, making it easy to clean off. I thought I might not use it much, but it’s actually turned out to be very practical.
Customer Review: I honestly probably wouldn’t have as many plants in my apartment if I didn’t have this mat!Repotting plants in a tiny apartment used to be an absolute mess—soil everywhere, water dripping, dirt stuck in corners I’d find days later. It felt like a full cleanup project every single time. But this mat completely changed that.Whenever it’s time to repot, I just pull it out and lay it on the floor or on my kitchen island. It catches everything—loose soil, water overflow, all of it. When I’m done, I dump the old dirt, rinse the mat off, let it dry, fold it up, and put it away. That’s it. No sweeping, no scrubbing, no stress.It’s also incredibly cost-efficient. Instead of constantly buying disposable coverings or dealing with potential floor damage and extra cleaning supplies, this one simple mat does it all—and you can reuse it again and again.If you live in an apartment (especially a small one) and love plants, this is a must-have. It’s easily the best plant-related investment I’ve made. Total game changer!
Complete Buying Guide for Perlite For Plants
Essential Factors We Consider
When shopping for perlite, key factors include particle size, purity, pH level, and intended use. Fine perlite (1-3mm) is ideal for seed starting and propagation, while coarse grades (3-6mm or larger) excel in potting mixes for adult plants, providing better drainage. Always look for 100% pure perlite without additives or fillers. A neutral pH around 7.0 is safest for most plants. For a balanced soil ecosystem, consider complementing perlite with best starter fertilizers for lawns to provide essential nutrients, as perlite itself doesn’t add nutrition.
Budget Planning
Perlite is an affordable soil amendment, typically costing between $10-$30 for 8-30 quarts. Bulk purchases offer better value per quart. If you’re also interested in organic soil enhancers, explore sea kelp for lawns for natural nutrient boosts that pair well with perlite’s structural benefits. Remember that investing in quality perlite now can save money on plant health issues later, such as root rot from poor drainage.
Final Thoughts
Perlite is a must-have for any gardener looking to improve soil structure and plant vitality. By choosing the right grade and combining it with other soil amendments, you can create optimal growing conditions. For comprehensive garden care, don’t forget to address potential weed problems with best weed killer for lawns when necessary, especially in outdoor containers where weeds can compete for nutrients.
Frequently Asked Questions
Q: What is perlite and how does it benefit plants?
A: Perlite is a lightweight, porous volcanic glass that improves soil drainage and aeration. It prevents compaction, promotes root growth, and retains some moisture without waterlogging. It’s sterile and pH-neutral, making it safe for all plants.
Q: Can I use perlite for all types of plants?
A: Yes, perlite is versatile and suitable for houseplants, succulents, orchids, vegetables, and seedlings. However, adjust the ratio based on plant needs; for example, succulents prefer coarser perlite for faster drainage, while seedlings benefit from finer grades.
Q: How much perlite should I mix with soil?
A: A common ratio is 1 part perlite to 2 parts soil for general potting. For seed starting, use up to 50% perlite. For cacti and succulents, increase to 50-70% perlite. Always adjust based on your plant’s requirements and climate conditions.
Q: Is perlite safe for organic gardening?
A: Yes, perlite is considered organic by many certifying bodies as it’s a natural mineral without synthetic additives. It’s sterile and doesn’t decompose, making it ideal for organic practices. Look for certified organic perlite if required.
Q: Can perlite be reused?
A: Perlite is inorganic and doesn’t break down, so it can be reused after sterilizing. However, it may retain salts or pathogens from previous use, so it’s best to use fresh perlite for seedlings or disease-sensitive plants. For general potting, reuse is fine after washing.
