Why are my sweet violet's leaves turning yellow?

Yellowing leaves on a sweet violet are less common and usually point to issues with moisture or soil drainage. Check the soil dampness first to see if you are overwatering.

Check these first

  1. Check the soil moisture by sticking your finger an inch deep.
  2. Ensure the pot has drainage holes at the bottom.
  3. Look for signs of standing water in the saucer.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow and feel soft or mushy to the touch. The soil stays wet for a long time and may smell slightly sour.

    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. Never let the plant sit in a saucer of standing water.

  2. Poor Drainage

    Possible

    How to tell: The plant is in heavy soil that holds too much water. The roots are struggling to breathe, causing the older leaves to yellow and drop.

    What to do: Repot the plant into a well draining potting mix that includes perlite. Make sure the container has adequate holes at the bottom. Only water when the top inch of soil is dry.

When to worry

It is normal for the oldest, lowest leaves to yellow and die off occasionally. Worry if many leaves yellow at once or if the new growth is affected.

Stopping it coming back

Use a light, airy soil mix and stick to a consistent watering schedule based on the dryness of the soil.

Questions people ask

Should I remove yellow leaves?
Yes, you can snip them off with clean scissors. This keeps the plant looking tidy and prevents potential rot.
Does yellowing mean I need more fertilizer?
Usually no. Yellowing is almost always about water or light. Only fertilize if the plant is otherwise healthy and has not been fed in months.
