## Customer Reviews

### ⭐⭐⭐⭐⭐ Well balanced slow-release granular fertilizer.
*by R***Y on June 18, 2025*

This is my second 10 lb purchase of 10 10 10 this year. Love this stuff! The granular fertilizer works well for my needs, and I use it confidently on almost everything, without concern, including various fruit trees and flowers.Tip: If you have any doubts about where and how to use 10 10 10, Google is a fantastic tool. I simply ask something like, Can I use 10 10 10 on my new Satsuma Mandarin tree in my State? Google responses are right on the money for me, and eventually you just know what to do and how to do it.Tip: If you have pear trees, you might want to go easy, and water in well. I burned the leaves just a bit.

### ⭐⭐⭐⭐⭐ Almost no fertilizer " dust" . All granular
*by J***E on June 1, 2025*

Perfect for my Green Giant Arborvitae. Slow release nitrogen is what they want. I have about 50 of them that are not fully mature. The soil they are in is not the greatest, so I have to feed them until they find their own food source. The bags the fertilizer came in are pretty big. I found almost no dust at the bottom of the bag. All granular. Spred it around the drip line of the trees, and watered it in. Heavy rains helped. Within 2 weeks, these trees started new growth ! Just what the doctor ordered ! Very happy with product. This will satisfy them thru the growing seaon.

### ⭐⭐⭐⭐⭐ Great fertilizer!
*by R***A on June 20, 2025*

This fertilizer is amazing! My trees went from slightly yellowish, dull foliage to glossy green leaves! I also have more fruit than last year. I like the fact that it’s granules so I can just sprinkle it. My trees died back this past winter. After using this fertilizer, they’re on the way to being beautiful and healthy again! I used this on grapefruit, lemon, and lime trees. It’s worth the money.
