Need help lowering pH levels!!
I have been growing blueberries for a couple months now and i recently checked the pH level on all 20 potted plants. They are all between 5.8-6.0 but i would like to lower the pH to around 4.8-5.0. I recently purchased some aluminum sulfate but havent applied it yet. I'm kinda nervous about burning the roots. All of the bushes are in 10 gal containers and have been fertilized with Florikan 17-5-8 (just in case the fertilizer makes a difference). If anyone can help me with lowering the pH levels safely with somewhat detailed instructions that would be awesome. Also, would it be alright to use Miracid to water the bushes after applying the aluminum sulfate?
