Troubleshooting
Italian jasmine problems — and how to fix them
Italian jasmine (Jasminum humile) 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.
Aphids on new growth
Soft new shoots in spring attract aphid colonies. Pinch off lightly affected tips or apply insecticidal soap. Strong, established plants usually recover without intervention if beneficial insects are present.
Sparse flowering in shade
Plants grown in too much shade produce abundant green growth but few flowers. Move or prune surrounding vegetation to improve light. Flower buds are set on previous year's wood, so avoid hard pruning in winter.
Frost damage in harsh winters
Although hardy to -5°C, prolonged cold or wet winters can damage stems. In Zone 7 or RHS H4 borderline sites, a sheltered south- or west-facing wall provides meaningful frost protection.
