Hello,

I am in zone 9. My roses definitely had black spot and a powdery appearance on the leaves this year. I have cut them back by 1/3 and raked all the leaves up. What else do I need to do between now and when they start blooming now?

I am going to try a dormant spray but the rose needs to be totally defoliated, which you should do anyway to start with fresh foliage.
You can't plant your new favorite rose if you are still watering your least favorite

Does that mean I cut the stems way back or just pull off all of the leaves? I'm new at this. Thanks for replying.

Where are you growing these roses? Their care will vary by area.

I am new to this but I read that you should prune them in February. Do I just chop them of or is there a certain length I should leave them? Thank you

You may trim them to suit yourself and the location. There is no magic amount that you must remove. Cut off any dead wood and anything growing in an inconvenient direction.

Pull off ALL the remaining foliage. The biggest thing in your zone is water. Water is the life blood of your roses. Wet, but not soggy.
It's a rose!!! It has nothing to do with life and death.

I am in zone 9 and the foliage on most of my roses is brand new; I wouldn't want to pull that off. No lack of water here recently!

Actually, if you've pruned them as far back as you care to, and you want to use a dormant spray, you can just go ahead and hit any old leaves with the spray. They will die, dry, and either fall off or blow away. You can rake them out of the beds.

In the same vein, how hard you prune should be dependent upon the roses you are dealing with. Many of the old roses don't profit from the hard pruning modern HybridTea roses typically get. Tea and China roses really don't benefit from it at all ... pruning for shape, and removal of dead growth is about it.

And while we're at it, I should note that I am regularly horrified by seeing even modern roses -- in my climate -- pruned down to maybe 6-inches. You simply don't need to do that in Southern California. Roses treated that way commonly grow smaller with every passing year of brutal pruning, and often finally just give up the ghost.

Digression: The presence of fungal afflictions on your roses last year isn't going to be solved purely through pruning and leaf removal. It could be that you planted varieties that suffer from fungus in your region, that the roses are located in a spot that is not sunny enough -- or too sunny and dry, so they don't get enough water -- or too damp! Or it could be that your roses are just young, and their immune systems need time to develop, to fight off the blackspot and powdery mildew you mentioned.

Hi there. I would think that spraying of sulfur would help with the blackspot and mildew. Ask about it at you local garden center. Just add some to a spray bottle and use it on your affected roses.
