Troubleshooting
Brewster Lychee problems — and how to fix them
Brewster Lychee (Litchi chinensis 'Brewster') 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.
Iron chlorosis
Interveinal yellowing of new leaves is caused by iron deficiency in neutral to alkaline soils. Apply iron chelate as foliar spray and soil drench every 6–8 weeks during active growth. Acidify soil with elemental sulphur annually. 'Brewster' is more susceptible to this problem than some other cultivars.
Failure to bloom
Lychee requires a chilling period (temperatures of 10–15°C for 4–8 weeks) combined with dry conditions to trigger flower induction. In consistently warm subtropical winters without dry stress, flowering is unreliable. Withhold water strictly in winter (November to January in northern hemisphere) and avoid nitrogen fertilisation from September onward.
Fruit cracking
Irregular moisture — especially rain or irrigation after a dry period near harvest — causes rapid uptake that splits skin. Maintain consistent soil moisture as fruit approaches maturity in May–June. Mulching helps buffer soil moisture fluctuations. Harvest slightly early if heavy rain is forecast.
