The leaves on my mini rose are turning yellow

shadygarden_CO(z5 Denver)January 27, 2006

Help! My mini roses' leaves are turning yellow. I got a gift potted mini rose for Christmas and want to keep it alive until I can plant it outside. It was doing fine and I repotted it about a week ago, dividing the four plants and putting them in separate pots. They seemed okay, didn't wilt or anything, but now the leaves of the two largest are turning yellow. Could this be caused by spider mites? Or is it from overwatering? Any help would be appreciated. How do you know if you have spider mites?

Hi,

It could be both. But they do like to be kept moist, so I dont think thats it. They are very susceptible to spider mites indoors. You should be able to see them clearly by looking closely at the leaves & underneath the leaves. You will see little webs and small red/orange dots on them-those are the mites. They are very hard to treat, you will need a powerful fungicide. Follow the directions on the bottle and follow up if needed. If you dont have mites, let the rose go another day or 2 without water. You may also want to keep it on a moist pebble tray for humidity, but ONLY if you dont have mites. More humidity means more pests. Minis are just difficult to grow indoors for any length of time. Good luck!

See the thread below which contains many of the other threads that can help. It could be overwatering, it could be spider mites (In addition to what Jen said, hold a sheet of white paper under the leaves and shake, if there are little spots that look like pepper, those are spider mites), it could be not enough light.

Help! My indoor mini roses keep dying!

Thanks to both Jen and Diane for your prompt advice. I do not have spider mites, apparently, from examining leaves like you said. Also, I think it is likely overwatering because the leaves are yellow on the roses in the plastic pots (two) but not on the ones in the clay pots. The plastic pots came with trays that fit very close and tight so I am going to remove those and put other trays underneath, maybe pebble trays.

Thanks again,

Marlene

Marlene,

Ok, that is definetly it. I dont put some of my houseplants in plastic pots if I know they dont like too much water. Go w/the clay, just make sure it doesnt dry out too much.
