Why does your Citrus limon have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Citrus trees are sensitive to high salinity; an accumulation of salts from tap water or excessive synthetic fertilizers can cause osmotic stress, leading to necrotic brown tips. This prevents the leaf edges from maintaining proper hydration.
Lemon trees require consistent moisture levels; periods of drought followed by heavy watering cause cellular collapse at the leaf margins. This stress is often reflected first in the most distal parts of the foliage.
Citrus species thrive in humid environments; extremely dry air can cause rapid transpiration from the leaf edges that exceeds the root's ability to supply water. This results in crisp, brown margins.
A lack of micronutrients like Boron can specifically cause marginal leaf necrosis in Citrus limon. This deficiency often manifests as browning at the tips and sometimes affects new growth development.
