Troubleshooting
Arabian Jasmine problems — and how to fix them
Arabian Jasmine (Jasminum sambac) 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.
Sparse flowering
Too little light or cool conditions limit blooms. Give maximum sun and warmth, feed with high-potash fertiliser, and prune lightly after each flush to stimulate new flowering wood.
Cold damage
It is frost-tender and suffers below about 10°C. Move containers indoors before autumn cold; sustained cold causes leaf drop and dieback.
Spider mites
Dry indoor winter air invites mites that stipple leaves and spin fine webbing. Raise humidity, rinse foliage and treat with insecticidal soap or horticultural oil.
Yellowing leaves
Caused by overwatering, poor drainage or alkaline conditions/iron deficiency. Improve drainage, let the surface dry between waterings, and use an acidifying feed with chelated iron.
