Plant problems

Yellow leaves on a plant

Yellowing can be a normal change in one older leaf or a sign of excess water, drought, low light or stressed roots.

Water

Persistently wet soil with several yellow leaves points to drainage or root stress.

Light

Low light slows water use and can weaken growth.

Natural change

One of the oldest leaves may yellow while the rest of the plant remains healthy.

Problem

What to do next

  1. 1

    Photograph the whole plant and note which leaves changed.

  2. 2

    Check moisture, drainage and the recent watering history.

  3. 3

    Do not feed automatically; first confirm that the roots and growing conditions are healthy.

Observation

When to act sooner

  • Yellowing spreads from day to day.
  • The soil smells unpleasant or stems turn soft.
  • Several nearby plants develop the symptom.
Important

Do not start by feeding the plant. If the roots are stressed or the soil stays wet for too long, adding fertilizer may make the problem worse.
