Why is my Sims azalea wilting and dying?

Root rot is a serious issue caused by soil that stays wet for too long. If your plant looks sad despite having moist soil, check the roots immediately.

Check these first

  1. Feel the soil to see if it is soggy.
  2. Check if the pot has drainage holes.
  3. Gently pull the plant out to inspect the roots.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil feels soggy or swampy to the touch. The leaves may look limp and eventually turn brown or black.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the pot lacks drainage holes, move the plant to a container that allows excess water to escape.

  2. Poor drainage

    Possible

    How to tell: Water sits on the surface of the soil for a long time after watering. The roots will appear mushy and dark instead of firm and white.

    What to do: Repot the plant into a well draining mix containing peat moss and perlite. Trim away any black or slimy roots before replanting.

When to worry

If the roots are completely black and mushy, the plant is likely beyond saving. Act as soon as you notice the soil staying wet for more than a week.

Stopping it coming back

Only water when the top inch of soil is dry and ensure your potting mix is loose and airy.

How often should I water?
Water every 3 to 7 days, but only if the top inch of soil feels dry. Never water on a strict schedule without checking the soil first.
