Field forget-me-not · Myosotis arvensis

Why is my field forget-me-not suffering from root rot?

Root rot is a serious issue for field forget-me-nots that usually stems from sitting in soggy soil for too long. Check the soil moisture levels and the drainage holes in your pot immediately.

Check these first

  1. Touch the soil to see if it feels muddy or waterlogged.
  2. Lift the pot to check if water is trapped in the saucer.
  3. Smell the soil for a musty or rotten odor.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The stems feel mushy at the base and the soil smells sour or swampy. Leaves may wilt even when the soil is wet.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. If the plant does not perk up in a few days, gently remove it from the pot to inspect the roots for dark, slimy growth.

  2. Poor Drainage

    Most likely

    How to tell: Water pools on the surface of the soil for a long time after watering. The pot lacks holes or sits in a saucer full of standing water.

    What to do: Ensure your pot has at least one large drainage hole at the bottom. Empty the saucer 15 minutes after watering so the roots never sit in excess water.

When to worry

If the stems are black and mushy at the soil line, the rot has likely reached the crown and the plant may not recover. Some minor root browning is normal if the plant has been slightly overwatered once.

Stopping it coming back

Always wait until the top inch of soil is dry before adding more water. Use a well draining potting mix to keep the roots oxygenated.

Questions people ask

Can I save a plant with root rot?
If you catch it early, you can trim away the black, mushy roots with sterilized scissors and repot the plant in fresh, dry soil. If the majority of the root system is damaged, it is often best to start over.
How often should I water my forget-me-not?
Check the soil every 3 to 7 days. Only water when the top inch of soil feels dry to the touch.
