Easy to use and works!!

Super easy to use and the results are noticeable. I apply this every 2-4 weeks to my Thuja Green Giants and I am very pleased with it. The trees are dark green and growing like crazy! I simply attach it to my garden hose, turn the water on halfway, shake the bottle, and open it “ON”. I throughly wet the foliage and that's it….

Simple to use. Love that it's multipurpose

Overall this is simple to use. Not too heavy. I like that I can use it on everything so I don't have to switch out my products all the time. Sure it's not the strongest but it's a nice addition for plant growth. I like the sprayer for this, it's easy.
