Check these first

  1. Check the soil moisture with your finger.
  2. Inspect the undersides of leaves for tiny pests.
  3. Look for drainage holes in the bottom of the pot.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow starting from the bottom of the plant and the soil feels constantly soggy.

    What to do: Let the top inch of soil dry out completely before watering again. Ensure your pot has drainage holes so excess water can escape.

  2. Nitrogen Deficiency

    Most likely

    How to tell: Older leaves turn a pale yellow while the plant growth slows down significantly.

    What to do: Apply a balanced liquid fertilizer every 2 weeks during the growing season. Follow the label instructions to avoid burning the roots.

When to worry

It is normal for the very lowest, oldest leaves to yellow and drop as the plant matures. Worry if the yellowing spreads rapidly to the upper foliage.

Stopping it coming back

Maintain a consistent watering schedule and feed the plant regularly with a high quality vegetable fertilizer.
