Bonide 705 Aluminum Sulfate, 4-Pound

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 🪴🗣️💨

I bought this product and some related ones to help a Pin Oak with Chlorosis. I won't know until new leaves appear next spring if it worked or not, but early indication from my lawn, where I also applied this product, is the greenest in the neighborhood. I have a natural lawn and don't use chemical fertilizers.I'm currently having my lawn soil tested by a lab. When the lab results come back, if additional iron is needed, this is what I will use.

Worked like a charm on two necrotic blueberry bushes. The bag recommends the right amount depending on what you plan to use it on - such as potted plants or several individual plants in-ground or application on a large block of land - so it's relatively "user friendly". My blueberries are in giant containers so I used and amount suggested for that and after maybe 3 rains both plants greened right up. In fact they turned a glossy hunter green and looked better than they ever had. Good stuff at an affordable price.

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!

I used this to turn my hydrangeas blue. It did the trick!
