Answer: Winter Jasmine need to be cut back anually in summer to encourage the next year's flowering shoots. It should also be kept evenly moist, extremes of dryness or over watering could cause the leaves and /or buds to drop. Also, it need a cool period in fall (40F) in a brightly lit room for 10-12 weeks to form flower buds. Hopefully you have such as location to keep it going in the fall and early winter. A partly heated greenhouse would be best.
