best product for soil acidification
a year ago
I live in a region where the soil is alkaline. Bushes are easily get yellowish and prone to diseases. Some one told me most plants prefer neutral to acidic soils, otherwise it will have trouble getting nutrients from the soil. I applied this product one a year for all of my plants. They slowly turned into their normal colors.
Yes, I recommend this product.
