Geranium · Pelargonium x hortorum

Why are my garden geranium leaves turning yellow?

Yellowing leaves on your geranium usually point to a watering imbalance. Check the soil moisture first to see if you are overwatering or letting the plant get too dry.

Check these first

  1. Feel the soil to see if it is soggy or bone dry.
  2. Check the drainage holes for blockages.
  3. Inspect the undersides of leaves for tiny pests.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The lower leaves turn yellow and feel soft or mushy to the touch.

    What to do: Stop watering immediately and let the top 5 centimeters of soil dry out. Ensure your pot has drainage holes so excess water can escape.

  2. Nutrient deficiency

    Possible

    How to tell: The leaves turn a pale yellow while the veins remain green.

    What to do: Apply a balanced liquid fertilizer diluted to half strength every 2 to 4 weeks during the growing season. This provides the necessary minerals for healthy green growth.

When to worry

It is normal for the oldest bottom leaves to yellow and drop occasionally. Be concerned if the yellowing spreads rapidly to the upper foliage.

Stopping it coming back

Always wait until the top few centimeters of soil are dry before watering again.
