EspomaOrganic Soil Acidifier Soil Amendment; Lowers Soil pH and Turns Hydrangeas Blue! Contains Elemental Sulfur & can be Used for Organic Gardening 30 lb. Bag - Pack of 1

Product works great and is at a good price

I live in the Appalachian Mountains of Virginia, and I have alkaline clay soil. I have a 2-acre orchard with 45 highbush blueberry bushes, which prefer acidic soil. So, I have been using this Espoma soil acidifier for the last fifteen years to keep the soil at optimal acidity levels for my blueberry bushes.I buy these 30-pound bulk bags to save money, and I have found that the price seems to vary wildly from day to day. So, if you don’t need it immediately, check back frequently to see if the price goes down if it is over fifty dollars. This acidifier is the safest product out there that I have found that I don’t worry about burning my plants.The instructions indicate to use 2.5 cups of acidifier per established blueberry bush, but I have found that much is not necessary if you mulch with pine bark mulch, which aids in acidity levels as well. I make sure that I have a heaping amount of pine bark mulch around each plant, and then only need to add 1/2 cup of this acidifier per plant by sprinkling it over the mulch before a good rainstorm each spring.This method has yielded me gallons upon gallons of blueberries each year with minimal effort and minimal cost, making this 30-pound bag of acidifier a great value.

This fertilizer is great. I had great experience with this fertilizer. I used it to fertilize my hydrangea .I had huge blue blooms. I also used it to fertilize my raspberries, blackberries and strawberries. For the first time I got a record production.

Not much to say except it will lower PH and makes blueberries grow.

Fertilizer works great, blueberries are acid lovers. However it will be the last 30 lb bag that I order. Last two years I have ordered this every 3 months. This is the second time in a row the bag arrives split open and fertilizer is dribbling out. Will order smaller bags in the future and see if they survive. Absolutely no packing inside the oversized box, so the problem starts with the seller. The soil additive is heavy, my guess is the box was dropped multiple times. Between the two creates a mess for me at this end. Not worth the hassle of returning, besides I needed to spread it now. Wear a mask, sulfur is dusty. After heavy rains will need to reapply. Even though bummed by the split open bag the product is great.

Good quality and a good price exactly what I want. Happy purchase.

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!

This product works better than others I’ve tried to lower soil ph. And retail big box stores do not carry this size at this price.
