## Description

4 LB Aluminum Sulfate Lowers Soil PH For Acid Loving Plants Like Azaleas Camellias Gardenias Hemlock Holly Cedar Blueberry Etc Turns Hydrangeas Blue Includes Easy To Follow Chart Works In All Soil Types Box

Review: I grow medical Cannabis indoors in organic soil with organic nutrients and sometimes soil pH goes off balance and needs to be raised so i use Dolomite Lime powder and when it needs to be lowered I decided to give Aluminum Sulfate a try after doing some research I found out that Aluminum Sulfate can be used in organic setups and it's one of the fastest acting products. So I bought this 4 Lbs bag and didn't know how much to add to i started small at 2g per gallon of soil and after a few tries I was able to determine that the best ratio is 10g per 1 gallon of soil and i was able to lower the soil pH from 7.4 to 6.5 and my plants responded in a positive way and the deficiency went away after 5 days. 95% of deficiencies occur because of soil pH imbalance that's why it's very important to have the right products that work every time that you can rely on and this Aluminum Sulfate is 100% one of the products you can definitely rely on. Happy growing 🪴🗣️💨
Review: I have several hydrangea plants in my yard. Researched care on line. This product was recommended for vibrant color enhancement. Just sprinkled it around the bushes and watered it in and the color was deeper and brighter than ever!

Soil

### ⭐⭐⭐⭐⭐ Review
*by M***T on 2 July 2018*

It worked for me. My baby hydrangea started turning pink, and I was looking for soil acidifier to help. After researching online soil acidifiers and how to approach soil ph tempering, I tried this product. (My starting soil ph was 7). The hydrangea is quite young, but I took a chance. I applied a very small (not even a 1/4 of recommended) amount, then a couple of weeks later a few more sprinkles, then a month later a tiny tiny bit more. The color slowly turned to lavender then to light blue. I could probably use it again for a deeper blue. I can tell this product works fast, but I used it in small amounts adding more as I went so it didn't burn my plants. It's also loved by my roses and azaleas. I barely dust around them every month or so. They love it!
