We are new to taking care of roses. I have recently noticed that all the new growth is coming up with brightly colored red leaves, as well as, there are buds, but they shrivel up before they bloom. What do you suggest? Do we have a disease? I know rose bush leaves are supposed to be green. LOL!

You're right, rose bush leaves are supposed to be green. And, yours will turn green as they mature. It's perfectly normal and natural for the new growth to emerge red or with a reddish tint. As the foliage matures it will turn to a deep green color. Not to worry! As for the shriveling buds; could be water stress or it could be an insect problem. Investigate a little further by cutting open a few of the affected flower buds. You may discover a little bud worm (look for a hole in the sepals of the bud) or you may find midge damage. If you find evidence of insects, you'll want to use a product such as Orthene. Be sure to read and follow label directions so you don't harm your rose bushes. If you find no insects or insect evidence, there may be a fungal infection. Try pruning off the affected rose buds. If the next buds that develop have the same symptoms you may need to treat your roses with a fungicide. Look in the rose care section of your garden center and you'll find several products from which to choose.

Best wishes with your roses!
