Troubleshooting
Mauritius Lychee problems — and how to fix them
Mauritius Lychee (Litchi chinensis 'Mauritius') 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.
Erinose mite (Aceria litchii)
A microscopic mite that causes velvety brownish-red galls (erineum) on the undersides of new leaves, distorting and stunting young growth. Control with wettable sulphur or abamectin-based miticide applied at bud break in spring. Several applications at 7–10 day intervals are needed. Remove and destroy heavily infested new flushes.
Poor fruit colour
Insufficient chilling or heat stress near harvest can result in pale pink rather than deep red fruit. Ensure full sun exposure and avoid late-season nitrogen. In warmer climates, harvest at peak colour, as 'Mauritius' colour development is temperature-dependent and fruit left on the tree too long in heat softens and loses colour.
Alternate bearing
Like most lychee cultivars, 'Mauritius' tends toward biennial bearing — a heavy crop year followed by a light one. Post-harvest pruning to remove spent panicles and reduce canopy density, combined with balanced fertilisation, helps moderate this tendency. Avoid heavy cropping stress by thinning in bumper years.
