Ideal Temperature Range. The best temperature range for growing a successful lemon tree is between 77 and 86 F. Photosynthesis processes peak at the 86 F. Lemon trees prefer warm weather because it is typically coupled with sunny days for optimum fruit production.
Grapefruit become more hardy as they mature â young plants must not be exposed to temperatures below 10Â°C (50Â°F). Trees can reach 5m (16ft). A minimum winter night temperature of 10Â°C (50Â°F) is fine for lemons. Citrus limon is less cold tolerant than C. Ã meyeri, which survives down to 5Â°C (41Â°F). Limes and C. limon only tolerate temperatures down to 10Â°C (50Â°F).
