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

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!

Well I am going to be honest with this review. I havent used much of the competition but this really exceeded my expectations. We had a very very very wet spring this year and moisture is a roses worst enemy. I had so much black spot on my roses that I could not keep up. I was spraying the roses at a rate I was outside with the roses pruning and spraying more then my other house hold choirs.I bought a bottle of this at the local shop figuring I would give it a chance and at first I did not notice any thing new. (Obviously it takes a short period of time to work as it has to travel through the rose and in to the leaves) but after just one month the new leaves are so green and shiney with no sign of problems at all. I even had one rose that had shown signs of the RRD so I pruned it heavily, applied this and sprayed the rose constantly and so far the rose is growing so fast and beautiful it has not even exhibited one sign of the RRD after a period of 2 years that I have had it. I cant say it killed or stopped the RRD but I will say it really has took it from the ugly red stem that had it to the most beautiful abundant blooming rose I have yet to see. I even have neighbors and such stopping by to take photos of my roses.I am definately convinced while I cant say 100 percent this product is behind all the beautiful results I have seen I can definately say they have improved for some reason since I have began applying this.

Last year I had a garage full of different sprays, powders, granules… you name it trying to keep my roses alive and healthy. I live in the hot, humid south so this can be a daunting task with roses. It was so bad I was ready to give up the roses completely by season end. I read about this product and applied it before they leafed out in early spring. I just applied it again (6 weeks). I am absolutely dumbfounded at how well it has worked. Just a little black spot. No aphids, no thrips, no powdery mildew, no rust, nothing….I hope to never be without it!

This 32oz bottle will drench, using 1 quart water mixed with 2 oz product, 17 roses. Exactly 17. Not even close to 20. Plan accordingly. Does work wonderfully to prevent rose diseases and pests.

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!

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

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.
