What It Looks Like

A white, floury coating on leaves and stems -- not dirt, but a fungal growth. It thrives in still, humid air with cool nights.

The Fix

  • Improve airflow (a fan or open window).
  • Wipe leaves with a 1:9 milk-water mix or a baking-soda spray.
  • Remove the worst-hit foliage.
  • Avoid overhead watering that keeps leaves wet.

Preventing It

Space plants for air, keep humidity moving, and do not crowd them.

Frequently Asked Questions

Q: Is it contagious?

A:

Yes, spores spread to neighbours; isolate the worst.

Q: Will it kill the plant?

A:

Rarely, but it weakens growth and looks bad.

Q: Can I use the same spray as for pests?

A:

Neem helps; the milk/baking-soda mix targets fungus specifically.

Airflow is the cure and the prevention. Pair good habits with the pest identifier.
