Indoor Citrus & Avocado Seasonal Leaf Drop: Normal or Not?

Citrus Sheds Leaves Before Bloom; Avocado Is Deciduous

An indoor orange tree curling old leaves while new growth looks fine, and an avocado dropping all leaves with brown, stiff foliage, are both exhibiting normal seasonal behavior—even indoors.

Citrus (Orange, Lemon, Lime)

• Semi-evergreen: shed 50–75% of leaves in late winter/early spring before flowering.
• Trigger: changing day length, temperature flux, root zone conditions.
• New growth = tree is healthy. No action needed.

Avocado

• Deciduous in cooler/dry seasons. Leaves turn brown, curl, drop.
• Indoor conditions (lower light, stable temps) may alter timing but not the cycle.
• New flush follows. Do not overwater leafless plant—roots rot easily without transpiration.

Care During Leafless Period

• Water sparingly: only when pot feels light / soil dry 2" down.
• Bright light.
• No fertilizer until new growth emerges.
• Resume normal care with first flush.

Both trees are doing what they’re programmed to do. Patience.
