Little bottle

Small bottle with a big punch. Hopefully will clear up my brown spots. Time will see.

Better results than Trugreen!

Great product, definitely made a difference in my turf in thickness and color. Fair priced, fast shipping, and 1 gallon covered my 4 acre property. Will be buying again! Saving money from paying Trugreen and better results!

Best fertilizer you could ever buy for your lawn!

My lawn loves me. Thank you Petra Tools for making such a great fertilizer for my lawn. It was really struggling in this vegas heat so this concentrated pick me up sure did help boost it up. A little bit surely went a long way. I mixed 5 oz with water in my gallon sprayer and sprayed it evenly all over my lawn before the sunset then gave it a good sprinkle of water to soak it in. Within days it was nice green and luscious. I will definitely be stocking up on this often to keep my lawn happy. I highly recommend this product.

Excellent product!

My lawn went from turning brown to green in a week!

Small bottle, good for one treatment

Haven't used it yet. Instructions for use on the back of the bottle. I'm trying to get rid of my lawn and help the wild strawberries spread, plus I have lots of bushes scarttered throughout the yard, so we'll see how it affects my plants
