Espoma Organic Berry-Tone 4-3-4 Natural & Organic Fertilizer and Plant Food for All Berries. 4 lb. Bag. Use for Planting & Feeding to Promote Bountiful Harvest - Pack of 2

Ever since I started using this fertilizer on my Blueberries, they have thrived. More berries and bigger, healthier plants. It was recommended to me by an Organic Blueberry Farm in my area.T

Good product!! Always helps my berry bushes grow strong and healthy!!

Using for my strawberries and blackberries

Great product. My blackberries do well on it

I don't know how to assess efficacy other than to say my plants seem fine so far.However, as others on the Internet will tell you, have a look at Epsoma's Holly-tone compared to Berry-tone. Compare the formula, the price per pound, the availability of 4lb vs 27lb bags, and then make the right decision about which to buy.

My blueberry, raspberry, and strawberry plants are LOVING this. They all are blooming very well. Will definitely continue to use this to fertilize throughout the growing season. Best price I could find online for two bags.

I have to say. I have a very large blackberry grove. The fruit was quite bit less the year before. . lWow! a The berry supplier suggested just to pull the plants out and replant. I ordered and used Berry Tone! I’ve had so many blackberries, I had to start giving them away. I would give Berry Tone an A plus. Just wish I could find it in twenty five pound bags.

Gave this to my blueberries and strawberries. They are taking off for the spring. Both are loaded down with flowers and berries. Very excited.
