Bonide Rose Rx Systemic Drench, 32 oz Concentrate, Garden Insect & Disease Prevention for Roses, Flowers and Ornamentals

Amazing product! I’ve purchased 6 bottles over the years and will continue buying. Prior to discovering this product, my roses never really thrived due to black spots and aphids. Well, not anymore! This stuff does wonders and my roses are vibrant and healthy! It’s easy to use too! I truly stand behind this product and consistently recommend it to fellow gardeners.

I was skeptical at first, never used anything like this, but this stuff has truly changed how I garden. Followed the instructions when I first received it, I was able to get 2 treatment in before winter, and did my first treatment 1 March and that's when I realized how amazing this stuff is! The before photo is at a different angle, but the blooms on the after photo says it all!

Amazing stuff. Ended the black spot right away. I had used this brand before so I trusted it and was happy I did!

Greatly reduced appearance of black spot in all my roses. Simple to mix and apply at the base, drip line line of roses.

Perfect multi use item for roses. When using be sure to mix well.

So far so good! My roses were getting so unhealthy from a plethora of issues. I broke down and bought this to help prevent them from getting worse. Every rose I’ve used it on has dramatically improved within a week!

This is my first year using this product. I started using it when spring first started and then at the recommended intervals. First impression is that it does not mix well, no matter how much I stir there are still clumps. Not sure how this impacts the effectiveness. I can say that I have noticed a difference in the amount of blackspot my roses get. It took longer for them to develop it and it isn't as bad as last year, but it is still there. Although it says it also keeps pests away I can say it has done nothing to deter the insects. It seems to work better on the roses that aren't predisposed to blackspot in the first place. Not very impressed so giving it 3 stars since it does seem to be doing something.

My rose bushes leaves had brown spots and some were being eaten but insects. I used this product as directed and it works great. It can’t help leaves that are damaged but all new leaves come in very healthy. You must apply every six weeks to keep the bushes healthy. I wish it came already mixed rather than dealing with mixing it but I’m super please with the results. This is my second year of using this product.
