We bought these two grown Jasmine plants 2 months ago when they had a few flowers and healthy green leaves. But now it looks like they are afflicted with some disease.
We live in Pune, India. The weather these days is like Temp: 15 to 30 deg C, Humidity: 30 to 60%. The plants have been watered regularly. They were kept outside in a place which gets diffused sunlight (shade of the apartment building) most of the day. The plants were potted by a professional, so I am thinking that he would have taken care of the roots while transplanting. We did not add anything to the plants other than watering during the last 2 months.
What could be the issue? What should I do?
PS: Yesterday, after 2 months, we added some fertilizer granules and manure yesterday and moved them to an area which receives ample direct sunlight for a longer duration. Will that help?
PPS: The plant seems to be of the species Nyctanthes elongata (a.k.a. Jasminum elongatum. Here is a photo from happier times.
