Jobe's Organics Granular Soil Acidifier

If you have plants that need a lot of acid (in my case it's blueberries), you need to occasionally add some of this to the soil. It's easy to open, easy to distribute (just toss out on the ground around your plants), and nature will take care of the rest. Just take note of how much to distribute. My experience says that it's better to put too MUCH than too LITTLE.

This has done a great job of brightening up the blue and purple tones of my various hydrangea flowers. It brought my gardenia to life - doubling the size and blooms on it. It greatly increased my blueberry yields and I swear it made them taste sweeter. I've been very pleased and have continued to use this.

Ok ordered couple bags of this acidifier. Jobes is a well knows brand for fertilizers and things so a trust worthy company when it comes to plants. My complaint and why one star is off? Well quality control of the bag itself. It looks like the bag wasn't sealed quite correctly, shifted about an inch over, so the one end had the edge stick out once inch farther, and the other side one inch shorter leaving the bag open on that side about an inch. If you know what this acidifier looks like is very tiny round flat particles. basically some of it was out of the bag and in the box. I guess that's what you get when everything is automated, there is no quality control anymore. If it was packed by hand someone should have caught this. It's not worth sending back, but i'm sure i'm out a cup of the material. Anyways, if you need to lower ph (acid) then use this, i think a few blue flowers and blue berries need this to grow in high ph areas like Los Angeles.

Repeat buyer. This stuff is good!

We had planted a couple of blueberry bushes several years ago, and they just weren't growing. We decided to give this soil acidifier a try, and what a difference it made! Very easy to apply, just pour the granules around the drip edge perimeter once a month or so.

Excellent review. I will also take note of my experience with the fruiting outcome.

My wife amends her soil with this in her fig trees! If she likes it, I love it!!!!

If you have blueberries, this is a must. Never thought I could grow blueberries in san Diego. But this fertilizer is magic and easy to use. I do not have a green thumb, but jobes is easy to use and affordable. My blueberry plants/bushes love me and yield big crops because of jobes .

Excellent produit arrivé dans le temps prévu. Je suis très contente de mon achat

Needed this to amend my soil for my blueberries and it was very easy to work with!

takes 3-4 months to actually work. so I'm guessing at a rating.

used this product to acidify a very high alkaline soil...will test PH next spring. Easy to use product.
