Hello, Marilynn. Aphids love the new shoots of rose plants. You can view a post on Rose bush problems by clicking here. There are organic solutions also on that page also.
Thanks for commenting.

Hi Paul, My Firecracker Penstomon blumed beautifully this spring but now it looks really bad! Pretty much everything (leaves & bloom stems) has turned brown and dried up. Should I cut it all way back? Could I have watered it too much? Or not enough?
Thanks,
Karla

Hard to say what the problem could have been. Possible mites may have attacked it. Mite damage will turn plants brown then dry up. Can u send photo? To my email address?

Hi, Thanks for answering…for some reason I can’t seem to download my phone pics to this computer. ( I’ve done it before!) I did check closely and did not see any evidence of any kind of infestation.
(to my untrained eye)…We’re leaving for a month starting tomorrow so I just cut it all the way back and will see how it looks when we return. Thanks again!
