Love love love this product. At the beginning of this year’s season, I fed all my roses, new and old. The flush of strong healthy leaves was beautiful. It’s a great boost as the year goes. Have been using it for seven years.

I’ve been using this fish fertilizer on all my Heirloom roses (and non Heirloom roses) and all of them are thriving beautifully. Some of my roses are starting to have lots of buds thanks to this fertilizer. I really recommend it. Its a little stinky but it will go away in a couple of hours, so its fine.

As several have mentioned, this stuff stinks to high heaven. About makes me gag just using it. I am sure it does wonderful things for rosebushes, but I never got the chance to find out. I have lots of country critters out here where we live -- and I do tend to make them "backyard pets" so they come around often. Especially my raccoons. Well, I fertilized not even thinking about it and I came out the next day and almost all my rosebushes were completely DUG UP and out of the ground. (I have over 20). I about died. I had to get rid of one bush completely and others took all summer to recover, never performing like they should have because of the shock they were put through I imagine. So....if you have raccoons, I would not recommend using this because they will dig trying to find the fish they smell!

This even worked on my roses that I've had forever. I bought 3 new roses last year and bought fertilizer for them. Used it on a rose (not Heirloom) that has always been struggling. It bloomed!

I purchased several (5!) roses last spring. I followed the instructions for planting and I used the Fish Founders liquid fertilizer. My roses grew like crazy and bloomed well. I will continue using this fertilizer! It’s smelly, but apparently the roses love it!!
