Why older leaves decline first

Older leaves often show stress before newer growth. This is normal plant behaviour, not necessarily neglect.

What's happening

Plants redirect mobile nutrients — nitrogen, phosphorus, potassium — from ageing leaves toward newer growth. The oldest leaves yellow, dry, or drop first. It's a survival strategy: invest in the tissue most likely to produce energy.

Why this happens

Container plants have limited nutrient access. When soil is depleted, the plant cannibalises older leaves to fuel new ones. Small pots, rapid growth phases, and Indian summers (which increase metabolic rate) all accelerate this cycle.

What usually helps

Feed with balanced liquid fertiliser every two to three weeks during the growing season. Top-dress with vermicompost every few months. Remove fully yellowed leaves cleanly. Ensure pots aren't too small — root-bound plants shed old leaves faster.

What to expect next

Losing a few lower leaves is normal. New growth should stay green and healthy. If newer leaves also decline, check for nutrient deficiency or pests.
