I just noticed this fungus like growth on my rose bush stems. I'm unable to determine what it is and how to treat it. It's only several of the stems and is killing the bush. Any help would be greatly appreciated. Thank you!
Try Ridomil, which works great on my ornamentals when there is a fungal attack.
Why are the leaves on my prairie rose tree turning yellow and orangish? It just started a few days ago...prior to that the leaves were green with a reddish tint to them. How to fix?
It could be an insect infestation or even a fungus issue.
If it has been dry this can cause stress on the plant, the same stresses and issues can be problematic if the weather has been damp.
You can treat with Neem Oil. This works as both an insecticide and fungicide.
I also may suggest adding some Epsom Salt. If it is a nutritional issue, this can help.
Here are a few links for you.

If your rose tree was very full of foliage, and the temps have gotten hotter where you are, it could be just a normal response to the heat by the rose tree. When it gets very hot out, many rosebushes, rose trees included, will start dropping leaves in an effort to imporove air flower around and through the bush to keep cool and save on precious fluids. I will provide a link to an article for you to check out on this subject here: https://www.gardeningknowhow.com/ornamental/flowers/roses/yellow-rose-leaves.htm and this one too: https://www.gardeningknowhow.com/ornamental/flowers/roses/leaves-falling-off-roses.htm
I have a very old rose bush that I have neglected all summer. We are in a severe drought. How can I tell if it is too late to save the plant? Could it have just entered a dormant stage? Should I water it at such a late hour? I am not sure what kind of rose it is. It is a kind of old fashioned, deep red rose. The plant is as large as a small tree. Thanks for your time.
Most older roses have a very good root base established so watering it well is appropriate. I would recommend watering the rosebush with water that has both a product called Super Thrive and a good root stimulator mixed into the water. Water the rosebush with this mix the next 4 to 5 times it needs watering. In extremely hot weather many rosebushes will go into a bit of a dormant state just as they do in the winter. Once the weather starts to cool off they will normally start growing again. You could also take 1 cup of Epsom Salts and sprinkle it around the base of the bush, work it into the soils lightly and water it in.
I took a small portion of a friend's old fashioned rose and planted it in my garden a few years back (about 3). It has grown 2-3 feet tall and gets new growth but there are no bloom shoots on the new growth that appears each year. I don't know if it needs more sun or fertilizer. It gets enough water (I think). I did spray for aphids this year and caught them early so I don't think that is the problem. Please help me because this rose smells so good and is a cabbage sort (I think) and I want it to thrive. Thank you so much for any input you may have.
Here is a link to an article on this subject for you: https://www.gardeningknowhow.com/ornamental/flowers/roses/no-blooms-on-roses.htm I have given such rosebushes a cup of Epsom Salts, sprinkled around the base and watered in with some water that has a product called Super Thrive in it. This treatment seems to kind of kick start roses that are not performing well.
What kind of Rose bush is this?
I am sorry, but we did not receive your photo. The staff at Gardening Know How can assist you with plant identification if you provide a photograph or, at minimum, a really good description.
I would like to find out what the name of this rose is.
Here is a link you can go to and enter in known information about the rose, such as color and do a search for the rosebush. Hopefully you will find a matching photo of her here: http://www.helpmefind.com/rose/plants.php With the unique bloom form she has a photo at this great site should get you her name.
It looks like a miniature rose(s) planted in a way too small container. I would transplant it as soon as possible to a larger pot with drainage holes in it. It is truly hard to say which red mini rose this might be but it could be one named Merlot or perhaps one named Red Scentsation.
How do I deter squirrels from eating my rose buds and dianthus buds?
Perhaps, some of the suggestions in this article will help: https://www.gardeningknowhow.com/plant-problems/pests/get-rid-squirrels.htm
