EspomaOrganic 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

I’ve grown black raspberries for a few decades at this point… they’re naturally a smaller raspberry. I use this twice per season, once right before they break dormancy and again about 6 weeks before berries start ripening. I do all the other things you’re supposed to (pruning, watering, etc.) and I get decent sized berries but adding this fertilizer was a game changer… my black raspberries rival my reds and golden sun size now. Very effective product (water in a few times for maximum effectiveness), easy to apply (just throw some handfuls on), and it actually works! I originally tested it on half my plants to see if there was a difference… I now buy this every year. So yeah, a definite difference worth every penny. I’m now known as the raspberry whisperer.

My strawberries and raspberries are loving this stuff. They are absolutely thriving. Big healthy leaves and lots of fruit. One small warning, whatever is in this smells really good to dogs. After using it my dog kept trying to dig the soil and eat it. I had to keep her away from the plants for a few weeks until it was absorbed into the soil.

Some might say growing strawberries in Arizona is a fool’s errand, but I can tell you firsthand that is complete rubbish. Since adding BerryTone to my strawberry plants they are THRIVING. And the end result are delicious, sweet & juicy berries from both the Chandlers and Albions. I will definitely never be without this miracle fertilizer ever again. I’m now adding it to my blueberries and blackberries. Will keep you posted!

Packaged well, my purchase arrived on time and intact and was as described. Shortly thereafter, it was vandalized. The culprit may never be known.A lesson: no matter how well packaged, any fertilizer is a dog magnet. Don't be like me. Put it out of reach. Trust me. It plays havoc on the digestive track of dog. We were very lucky and Buddy is fine today.

Easy to use, love that it has clear and precise instructions. Love that it's organic. This was the first year we got blueberries after using.

The only fertilizer we use on our Berry's. Works on our blackberry, raspberries,and boysenberries.

My strawberries always thrive after applying BerryTone. It does not have an odor like some fertilizers do and seems to last for a while. I will continue to buy from Amazon as they seem to have the most reasonable price.

Will buy again and again.I have part sun-shade situation (not the best for most berries) and still getting some berries!
