By carefully monitoring temperatures and implementing protective measures, lemon tree growers can enhance the resilience of their trees against temperature extremes.

Temperature Tolerance of Lemon Trees

Lemon trees, primarily the Eureka and Lisbon varieties, thrive in warm climates. Understanding their temperature tolerance is crucial for successful cultivation.

Optimal Temperature Range

Lemon trees prefer a temperature range that supports healthy growth and fruit production. The optimal temperature for lemon trees is:

  • Daytime: 70°F to 100°F (21°C to 38°C)
  • Nighttime: 50°F to 70°F (10°C to 21°C)

Within this range, lemon trees exhibit vigorous growth and high fruit yield.

Low-Temperature Tolerance

While lemon trees can withstand brief periods of cooler temperatures, prolonged exposure can be detrimental.

  • Minimum Tolerance: Lemon trees can survive temperatures as low as 20°F (-6°C) for short durations, but this can lead to damage.
  • Frost Damage: Below 30°F (-1°C), lemon trees are at risk of frost damage, particularly to young trees and fruit.

High-Temperature Tolerance

Lemon trees are more resilient to heat compared to cold. They can tolerate high temperatures, but extreme heat may lead to stress.

  • Heat Stress Symptoms:
  • Leaf drop
