Fertilizer burn is one of the most misdiagnosed houseplant problems because its symptoms — brown tips, wilting, yellowing leaves — are nearly identical to overwatering, underwatering, and root rot.

Troubleshooting Guide

1 Why are the leaves on my lemon tree turning yellow?

Diagnosis: Nutrient deficiency (often nitrogen) or overwatering

Treatment: Fertilise with a citrus-specific fertilizer; check drainage; water when topsoil is dry.

Prevention: Feed regularly in growing season; use well-draining soil.

2 Why are the leaves curling?

Diagnosis: Aphids or underwatering

Treatment: Check for pests; if none, water deeply; apply insecticidal soap if aphids are present.

Prevention: Monitor for pests; maintain consistent watering.

3 Why isn't my lemon tree flowering?

Diagnosis: Insufficient light or lack of winter chill

Treatment: Move to sunniest spot; ensure temperatures cool slightly in winter (but above freezing).

Prevention: Give full sun and a winter rest.
