Review: Fantastic product - This Espoma Organic Soil Acidifier is amazing! I've been trying to get my hydrangeas to turn blue for ages, and this product finally did the trick. It's so easy to use and I love that it's organic and safe for my garden. My hydrangeas are vibrant and beautiful now! Plus, the 30 lb. bag is a great value. Highly recommend for anyone looking to lower soil pH naturally! It works great with my blueberries!
Review: Make your acid loving plants happy - If you are growing blueberries, hydrangeas or any acid loving plant you need this. I used this to prep the soil prior to planting acid loving plants to create the appropriate soil acidity (pH). Then yearly to help maintain the appropriate pH. The first thing you need to do is get a soil test done so you know your current soil acidity level. Then follow the bag instruction to bring your pH to the level you desire. Then yearly maintenance. Make sure you work this fertilizer into the soil and just don't leave it sitting on top. In addition there are other things you can use to adjust pH like adding peet moss and acid fertilizers. I planted 14 varieties of blueberries and I added this to the soil to adjust pH to the optimal level for blueberries. This stuff just works. Within one year my blueberry plants went from a twig to a nice bush already producing blueberries. If you want big blueberries or amazing hydrangeas this is a must have to get the correct soil pH. Pros: Creates a more acidic pH for your plants Easy to use Good instructions I get big blueberries now ;) Cons: None after using for 4 years

### ⭐⭐⭐⭐⭐ My GoTo Organic Plant Fertilizer for Acidic Loving Blue Hydrangea/Plants for 20 Years
*by G***L on December 3, 2023*

I think this is one of the best all-around outdoor organic plant fertilizers for blue flowering acidic loving plants such as Hydrangea that you can use. I've been using Espoma UL30 Organic Soil Acidifier Fertilizer for 20 years around all of my blue flowering plants / shrubs that thrive in Acidic soil. This includes my rhododendrons, hydrangeas and blueberries. It's great because it's organic, it's slow-release (takes time to get to the roots with watering and rain so can't burn) and super easy to apply. Because it's slow-release, I just sprinkle it on top of the soil all around the plant and then just use my finders to work it in. Note that this fertilizer is not for plants that don't want/thrive in acidic soil. For a general all-purpose fertilizer, my go to is Espoma Organic Plant-Tone 5-3-3 Natural & Organic All Purpose Plant Food.
