Common Jasmine problems — and how to fix them
Common Jasmine (Jasminum officinale) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Few or no flowers
Caused by too much shade, hard or mistimed pruning that removes flowering wood, or excess nitrogen. Site in full sun, prune right after flowering, and use a high-potash feed.
Overgrown, tangled growth
This vigorous climber quickly becomes a congested mass. Thin and shorten stems after flowering each year to keep it open, healthy and within its support.
Aphids
Soft new shoots attract aphids that distort growth and excrete honeydew. Blast off with water or treat with insecticidal soap; encourage ladybirds and other predators.
Winter dieback
Cold, exposed sites can scorch or kill stem tips in hard winters. Grow against a sheltered, sunny wall and tidy out frost-damaged growth in spring.
