Troubleshooting
Chilean Jasmine problems — and how to fix them
Chilean Jasmine (Mandevilla laxa) 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.
No flowers
Too little light or excess nitrogen drives leafy growth at the expense of blooms; move to full sun and switch to a high-potassium feed.
Winter dieback
Top growth collapses after frost; this is normal for M. laxa. Mulch the crown heavily and cut back dead stems in spring as new shoots emerge.
Aphids and whitefly
Soft new growth attracts sap-suckers that cause sticky honeydew and distorted leaves; rinse off and treat with insecticidal soap.
Yellowing lower leaves
Usually overwatering or poor drainage; let the top few cm dry between waterings and ensure pots drain freely.
