They had the product I needed at the right price. The product hadn't shipped and they called me a real person and let me know what was going on thanked me for my order and also provided other information for my garden and pests I was dealing with.
I found something similar on another site. This one was what I was looking for. Really sturdy and adorable, perfect for my new shelves.
Thank you so much, Jill! We're delighted to hear you found exactly what you were looking for and that the item fits perfectly on your new shelves. We truly appreciate your feedback and look forward to supporting your projects in the future.
I read about expanded shale as a soil amendment and wanted to give it a try. I could not find it locally but round it at Monster Gardens. Their on-line shopping app was easy to use and my purchase arrived very quickly. I will use Monster Gardens again, for sure.

This is my first time purchasing from Monster Garden and I found the web site to be very useful and helpful with the products suggestions. Delivery was great (easy to track and right on delivery estimation) and product was packaged very well. Hopefully the kumquat and the citrus trees will be just as happy.
Thank you so much, Alice, for sharing your wonderful experience! We’re thrilled the website was helpful and that your delivery arrived just as expected—we hope your kumquat and citrus trees thrive and bring you loads of joy. Looking forward to supporting your gardening journey again soon!
I was in the market for black lava rocks. I searched local retailers, including the Home Depot, with no luck. I finally gave in and purchased 10# bags from Amazon. The seller had the gaul to advertise their rocks as "1/4 to 1/2 inch size." I don't think I found a single rock measuring smaller than 1/2" and the majority of them were larger. Not knowing any better I went ahead and used 70# to repot many of my cacti, succulents, and bonsai.
Something I decided to search online again to see if there was anyplace that sold black lava rocks in larger quantities. I didn't expect the rocks to be any smaller; I thought that was just how things are.
I found Monster Gardens and ordered two 24# bags. What a difference! The rocks really are 1/4". They works so well it's taking a great deal of self control to not start over repotting the plants I repotted with the boulders.
I'm very please with this product and will order them again.
Thank you so much, Sincelia, for sharing your great experience and kind words about our lava rocks! We're thrilled to hear they are just the right size and perfect for your plants. We look forward to helping you with any future gardening needs!
Fast delivery. Shipping was pricey, half the price of the item. Hard to find item.
Gary, thank you for acknowledging the fast delivery. We understand that shipping costs are a concern, especially for hard-to-find items, and we're actively exploring ways to offer more flexible shipping options to keep overall prices fair. Your feedback helps us improve these areas going forward.
All items I ordered shipped quickly and arrived in good condition. Easy website and great prices.
Thank you, Lisa, for your kind words! We're delighted to hear the ordering process was easy and your items arrived promptly in perfect condition. We look forward to helping with all your future gardening needs!
I ordered my Bokashi bran from Monster gardens based on price. The shipping cost was very reasonable and I received the product very quickly - within a few days of ordering. I recieved shipping notifications via email.
My mailman left the package in a puddle. Fortunately it was packaged so well that it didn't affect the product. It was packed in paper surrounding a box, both of which were taped well. The box contained a burlap sack which then contained a plastic bag with the bran.
I'm looking forward to using it.
Thank you, Brad, for sharing your great experience and kind words about the packaging and speedy delivery. It means a lot to hear that everything arrived safely even through such an unexpected wet encounter—we hope it helps make your gardening projects even more enjoyable! Looking forward to supporting your green thumb in the future.
You gave us exactly what we needed in a timely manner! Thank you!
Thank you, Branson, for your kind words! We’re thrilled to hear the tote liners arrived right when you needed them. Supporting your projects quickly and reliably is what we strive for every day.
We ordered within seconds of finding the planter. It was being processed for shipping in less than 24 hours and arrived within days of ordering.

Original order had a bag of product that was damaged, replacement was shipped and delivered very satisfied
Mark was amazing. I have great confidence in this team
Timely delivery, great price based on fertilizer price increases.
You guys were the only one I could find that carries the cutting edge louder powder. I will continue to order from you guys, I noticed you are a smaller shop and I know what it means to support smaller operations these days as I worked in a hydroponic shop in Asheville that recently went out of business. Keep doing what you guys do!
Apparently they were out of the size I had ordered. So instead they shipped a size larger. Thank you!
Found exactly what I was looking for, easy to order and received in a just over a week.
Decent price, but I found free shipping and the same price at another site after I ordered so I'll probably go that route next time
Quick easy checkout with PayPal shipping cost was semi reasonable
