I just moved into a new house and am a very beginner with this gardening, so any help will be appreciated. About 3 months back I bought two J&P mini roses Honey parfume to put on either side of my front door-they are in large urns. About the last month I have noticed black holes in the rose buds before they have even opened and noticed what looked like small 1/2 inch grasshoppers with antenna that are black and white. I have used water to spray them off, it got rid of some but not all do I just stay consistent with the water or is there something I can use? One other question is I live in the Dallas area and the first bloom of roses were wonderful but now the buds seem to dry up and become brittle before they even get fully open-any ideas. Thanks for any help you can give.
