Troubleshooting
Malabar Quisqualis problems — and how to fix them
Malabar Quisqualis (Quisqualis malabarica) 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.
Failure to flower
Insufficient direct sunlight is the most common cause. Ensure the plant receives at least 6 hours of direct sun daily. Excess nitrogen fertilisation also suppresses blooming — switch to a low-nitrogen, phosphorus-rich feed.
Scale insects
Brown or white waxy scales appear on stems and leaf undersides, causing yellowing and dieback. Treat with horticultural oil spray or systemic insecticide and improve air circulation.
Root rot in poor drainage
Waterlogged soil causes rapid root rot, particularly in cooler temperatures. Plant in raised beds or add coarse grit to heavy soils to ensure rapid drainage after rain.
