My orange jasmine plant that i bought from a florist in February had been blooming wonderously through march (indoors, near a well lit window), in the first week of april i saw some new leaflets and lots of new buds. The buds came to nearly blooming but the flowers never opened up, turned yellow and fell off. The new leaflets started looking limp. The lush dark green foliage on the tree has started shedding like crazy, loosing 100 plus leafs a day. Most of the leaves are turning a dirty brownish green overnight before falling. The tree is nearly bare now except for some 15-20 red fruits here and there. I have checked the watering and the soil for bugs but not found any. I need guidance soon please!
