Q.Rose Bush
I have had a rose bush for 12 years. It has bloomed beautifully every year until this past summer. I trim it back every year and this year it grew back long gorgeous canes but not a single bud. Why would it grow and not have buds? It would get the dark purple color like it always did when it was ready to bud but no buds. The canes are a nice dark green and healthy looking. Why didn’t I get roses this year?
Unfortunately your 12 year old rosebush may have partially died. When this happens, usually the top part of a grafted rosebush dies. The part we have enjoyed so much. The hardy root stock it was grafted to takes over and sends up it long canes which usually do not bloom for a couple years. When and if it does bloom the blooms are typically flat and not the color of the rose we desired and enjoyed. It is best to prune such roses down, dig them out and replace with a new rosebush that we like the looks of. Here are some links to articles for you to check out on this:
