Troubleshooting
Korlan problems — and how to fix them
Korlan (Nephelium hypoleucum) 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.
Poor fruit set in cultivation
Korlan is rarely cultivated away from its native range and may fail to flower without the correct seasonal cues (slightly cooler, drier period). Grafted material is extremely scarce; most plants from seed take many years to reach reproductive maturity.
Root rot in low-drainage soils
Native to well-draining forest soils; compacted or waterlogged soils in cultivation cause rapid root decline. Always plant in raised beds or well-amended free-draining soil.
Scale insects and aphids
Young succulent growth is vulnerable to scale insects and aphids, especially under stress. Monitor new flushes and treat early with neem oil or horticultural soap spray to prevent colony establishment.
