Espoma Organic Soil Acidifier 6 lbs Bag with PH Soil Test Strips 20 ct. Bag - Acidify Soil, Enhance Hydrangea Color, Embrace Organic Gardening, Achieve Optimal Soil Balance

This product is in granular form, like fertilizer, and the hand-held spreader makes it easy to apply. It takes a few months for the bacteria to convert it and lower the PH.

These have helped turn my pink hydrangeas to blue, but it is a slow process by next year. They should be coming out blue.

The best all-purpose fertilizer. Easy to use, not too odiferous and my transplants look well! A very affordable option.

Used this to acidify some high clay soils around my trees. Will review again in the spring when they start their usual spring growth.

I just received the package and it got here fast and exactly as described. I can't tell you how good it is because it just got here. Please give people time to use the products if you want a good review
