Q.Please Could You Advise How To Make This Rose Pot Plant Healthy Again?
I have attached a photo of a mini rose pot plant that was given to me as a gift 2-3 weeks ago. When I received it, it was healthy with a few open red roses. Very quickly, I think within days, some of the leaves were yellowing, new pink buds were dropping before they even got the chance to open and once of the stems now looks completely brown, dry and more like a stick! I started with it on the kitchen window sill (south east facing). The soil is moist and I have watered it only when the top soil felt like it was starting to dry. I have put it outside in the garden when not raining to try to give it some air without overwatering. Iām not sure what to do to make it healthy again š

They are not meant to stay in that container for long. They overcrowd them when planting to make it appear more full.
In order to make them healthy again, you must separate them into their own containers, and care for them as best as you can. These articles will help you to do so:
