## Description

Product description Experienced growers dig it!

Review: Good quality fertilizer - We have a small farm in Hawaii. The fertilizer needs of our plants varies greatly, and even within one species, their yearly needs change. Lychee is far different than pineapple, and they are vastly different than coffee. I have a habit of ordering my N-P-K fertilizers separate, and using a 10-10-10 or 16-16-16 fertilizer as the base. I do the math to mix the different fertilizer contents for the plants. This source for potassium is good quality and a good value for the money. Varying the mixes improves plant health, growth, and has effectively improved our yields. It is easy to use and here we need lots of potassium so the flowers will set fruit.
Review: excellent fertilizer - My dirt is not so good for fruit trees, finally I had fruit using this fertilizer!

## Questions & Answers

**Q: Is this good for peach trees?**
A: not knowing your level of expertise, the N-P-K numbers are Nitrogen (Greens), Phosphorus (blooms), Potassium (Roots).  With this being 100% Potassium/Potash, it will help with roots, and some with blooms.  if that is what your peach tree needs, it will definitely help!  (I bought this for a fig tree where a gopher got it's roots.  I also bought this same brand of Phosphorus. when i pulled out the fig that didn't make it, i put two handfuls of each of these products in the hole, and moved a potted lime tree into this place.  That tree is doing FANTASTIC!!  Tons of new blooms in just two weeks.  I plan on adding the two together to my apricot that didn't have many blooms the last two years.)  I hope this helps!

**Q: Is this organic?**
A: I have checked my bag and if it is organic, it isn’t written anywhere on the bag.  So my answer would be no, it’s not organic.

**Q: Can I put this in an irrigation system?**
A: This is granular.  size of bb's.  if your system has a way of breaking down the 'pellets' I think you could.

**Q: Can this be ukase for loving plants ?**
A: I don't see why not.  I used it on the lawn.   If you don't over do it you should be okay
