Question
I have a seven sisters rose bush that has been planted outside my apartment for about 7 years. Ive lived here a little over 3. I live In Columbia South Carolina, its been dry and hot for weeks now, no rain for atleast two and my roses only get water I give them . I have a mildew and uncontrollable aphids. I tried a *garden Safe* fungi, insecticed oil type treatment, it doesnt kill the aphids and the mildew is controlled for 3 or 4 days then comes back with a vengeance. It was beautiful in early spring, even had blooms, which I had to cut back due to die off and infection. Is there anything I can do ? I will be happy to provide any other information you might need . Ive become quite attached to the bush and hope to take part of it with me when I move next spring, provided I can get it in good health by fall to either propogate or dig up one of the main root balls. Thank you for any help you can provide.  

Answer
Seven Sisters is one tough old rose, you couldn't kill her if you tried. When a rose is planted next a solid wall and weather conditions are right, then it can get mildew very quickly especially if the rose is prone to it and Seven Sisters is. Any rose fungicide will get rid of your mildew problem. If you are into organics then try spraying daily with 1 tablespoon baking soda to 1 quart of water may keep it under control for you.
Mother aphid lays her eggs on the tips of the rose canes so the little ones can start eating the new growth as soon as they hatch. Once knocked off the rose they cannot get back up again and birds eat them like candies. Just spraying with the hose should remove them as that is all that is needed to get rid of them.
Seven Sisters is a rambler and the best time to try and propagate is immediately after it has flowered so now is okay. Take cuttings off from a tip of a cane that has already flowered about 8 inches long. Cut the dead flowers off and leave only the last two leaves at the top.
Here is an easy  method to propagate cuttings that works well. Place your cuttings (take 5 at least as some may not take) into a one gallon pot filled with either a good sterile potting soil or sand, perlite, peat moss, or whatever mix that you have. Cut off the bottom and remove the label from a 2 liter soda pop bottle and place the bottle, with cap on, over the cutting, slightly burying the edge into the soil. You'll be surprised how well this works as the plastic jug works as a mini greenhouse, and allows plenty of room to add water around the outer edge without removing the bottle. The bottles are placed under cover where they get little direct sun. The translucent and clear bottles seem to work the best, however, translucent bottles are much cooler and should be used for cuttings placed in the sun. When the cutting gets new growth, undo the cap of the bottle but do not take it off at this time. You need to harden the cutting first. After a few more days, take the cap off entirely, then after a few more days, remove the bottle. Leave the cuttings in the pot until you are in your new home.If they get mildew just use any rose fungicide at half the strength. Hope this helps.
