Guascas · Galinsoga parviflora

Why is my Galinsoga wilting and the soil smells bad?

Root rot is almost always caused by soil that stays too wet for too long. Check the soil moisture and the smell of the pot immediately.

Check these first

  1. Smell the soil for a foul, rotting odor.
  2. Check if the pot is sitting in a pool of water.
  3. Press the base of the stem to see if it feels soft or mushy.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves will look wilted even if the soil is wet, and the stems may turn mushy or brown at the base. The soil might also have a sour, swampy odor.

    What to do: Stop watering immediately and let the top inch of soil dry out. If the plant is in a container, ensure it has drainage holes and is not sitting in a saucer of standing water.

  2. Poor Drainage

    Most likely

    How to tell: The water sits on the surface of the soil for a long time after you water. The roots are suffocating because they cannot get enough oxygen.

    What to do: Repot the plant into a container with better drainage holes. Use a light, airy potting mix that allows excess water to flow through easily.

When to worry

If the stems are black and mushy at the base, the rot has likely reached the crown and the plant cannot be saved. Minor wilting that recovers after a day of drying out is usually fine.

Stopping it coming back

Only water when the top inch of soil feels slightly dry to the touch, and never let the pot sit in a tray of water.

Questions people ask

Can I save a plant with root rot?
If you catch it early, you can trim away the mushy roots and repot the plant in fresh, dry soil. If the roots are mostly black and slimy, it is usually best to start over.
How often should I check the soil?
Check the soil every 2 days since Galinsoga likes to stay evenly damp. If the top feels dry, it is time to water.
