## Description

A fertilizer blended specially for acid soil loving plants like rhododendrons, azaleas, hydrangeas, evergreen trees and shrubs, blueberries, raspberries and other plants that thrive in a low pH soil.

Late fall applications promote healthy root growth and boost resistance to extreme winter temperatures.

Review: Down To Earth products are awesome when you are looking for top quality, organic suplements for your plants. This stuff works, like all the products I have purchased from Down To Earth. I would, without reservation (and have), reccomended their products. Value for money is there when you factor in the quality of what your plants are getting and thus, if an edible, what you are getting. It helps growth of your plants without doubt. There is no real smell to it, as long as you are a few inches away from it. Otherwise, yes, you can notice a smell of something. It's not a smell that would make you feel sick or anything though. It's just there. If you are a gardener, I know you have smelled Waaayyy worse than this stuff. As far as durability, I thought about this, and honestly, I don't think it applies to this product. However, the box is of sufficent durability to contain the product inside of it's clear plastic bag inside the box. Don't get the bottom wet though, as it could give way when you pick it up and you could have a mess on your hands.
Review: within days I noticed a huge difference in the health of my blueberry plants. They loved it. Will be getting more for sure!

*by B***Y on 22 May 2024*

I ordered this August 2023. I just brought it out to use today and after applying to my 3 blueberry plants I realized it expired in April 2022. For $70 this is inexcusable.
