Whoops. Wrong board. Can a mod move this to the Garden board? If not, please delete it. Mod note: Thread moved.

Sadly, all my rose bushes, although still doing really well, have a lot of issues going on with them. The leaves have dark spots, seems to be a lot of spiders, the wasps or whatever they are love the roses (sucks when I have to trim them), and then I saw this (see pic). OMG, yuck. Are those aphids? How do I get rid of them? I had put ladybugs on the bushes a few months back and they're there, but maybe they can't control that many bugs.

I use Bayer All in one, Rose & Flower on my roses. It is a granular systemic that kills bugs, diseases and fertilizes. I apply it on the holidays (St Patrick’s, Memorial Day, July 4th and Labor Day).

It works beautifully and only harms bugs that chew the plant.

Are you sure it doesn't cause harm? According to this, it does: "Insecticides containing imidacloprid, including the Bayer Advanced 3-in-1 line, are a case in point. Imidacloprid kills the honey bees that help feed the world."

Yes, that's a heavy infestation of aphids sucking the juices out of the roses. And yes, there are way too many of them for your free ranging ladybugs to keep up with all of them. For a really quick instant fix - first of all check to see if there are ladybugs on the roses and if there are some then hose down the bushes with water to knock off any ladybugs that are on them so the ladybugs will go away for a little while. It's for the ladybug's safety. Then fill a big spray bottle with soapy water (you can use dish soap) and spray the rose plants and aphids very liberally with the soapy solution.

Saturate every inch of the plants everywhere including spraying under the leaves and down all the stems. The plants should be dripping wet with soapy water all over. Let sit and drip dry for an hour, then use the garden hose to hose the plants down thoroughly with fresh water. It will wash off the soap and all the dead/dying insects as well as aphid eggs.

If necessary (or just for your peace of mind) you can spray the soapy water on a second time again, only do a light misting the second time but still mist it all over and then leave that soapy water on overnight. Rinse again first thing in the morning with water from the garden hose. They should be okay for several weeks after that before more aphids come back but you should still check them every day or two to be on the safe side.

I use the soapy water any time I see aphids or spit bugs on any plants and don't usually have to worry about those plants getting those bugs on them again for several weeks after a treatment, if at all.

Yes, it’s possible, but I still use it. If I feel as though the plants are not struggling with an ailment, I switch to plain fertilizer.

Those are aphids. Put some liquid dish soap in a plant- or hose-end sprayer and spray them.

You could also get a new batch of ladybugs. They munch on the aphids, and then move on when they're mostly gone.

Black spot is a fungal disease. It looks like your rose is planted under a tree. Transplanting to a sunnier place this fall might help.

Thanks everyone. I'll get on the soapy water thing as soon as the rain let's up. Does it matter what kind of soap I use? I think I've read to use Dawn. Yuck, I just couldn't believe how many there were!!!

Actually, it's under a rose topiary or whatever you want to call it (see attached), but the spots are on everything. It has been a weird summer (humid, rainy, overcast) where nothing is drying out except every so often.

This is my concern too. My husband would rather buy more ladybugs to help. Also, I'm trying not to use pesticides since I've been wanting to make stuff out of the petals since I have so many!

For that photo that I put up, if anything, all I'm going to do is cut that stalk (it doesn't belong there anyways), however, it just means the rest of it is probably invested too. Yuck. Do I need to wait for it to stop raining? Does it need to be a warm day or anything? I hope I don't kill any of the good bugs. My poor rose bushes.

Isn't that Rose Rosette?

I believe you can fight it, but you won't win. If I'm right, the bushes have to be replaced.
