Why is my Heather plant wilting and dying?

Root rot is a common issue for Heather when the soil stays soggy for too long. Check your drainage holes and soil moisture first to see if the roots are drowning.

Check these first

  1. Touch the soil to see if it feels wet or muddy.
  2. Inspect the bottom of the pot to ensure drainage holes are not blocked.
  3. Smell the soil for a musty or rotten odor.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The foliage turns dull and mushy, and the soil smells sour or swampy.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant is in a pot, ensure it has drainage holes and is not sitting in a saucer of water.

  2. Poorly draining soil

    Possible

    How to tell: Water pools on the surface for a long time after you pour it.

    What to do: Repot your Heather into a sandy, acidic potting mix that drains quickly. Avoid heavy garden soil that holds too much moisture.
