Troubleshooting
Chinese Mulberry problems — and how to fix them
Chinese Mulberry (Morus cathayana) 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.
Wind damage to large leaves
The exceptionally large leaves are prone to wind tearing and shredding in exposed positions, which reduces photosynthetic efficiency and ornamental appeal. Plant in a sheltered location or use nearby windbreak planting. Avoid frost-pocket sites where late frosts can damage new growth.
Powdery mildew
The large leaf surface is prone to powdery mildew in dry summers, especially when planted in partially shaded or crowded positions. Ensure full sun and good air circulation. Apply sulphur or potassium bicarbonate fungicide at first sign of infection.
Fruit fly (Drosophila spp.)
Ripe and overripe fruit attracts fruit flies in large numbers. Harvest promptly as fruit ripens and remove fallen fruit regularly. In areas with spotted wing drosophila (SWD), fine-mesh netting may be needed as fruit colours.
