Troubleshooting
Polka Dot Plant problems — and how to fix them
Polka Dot Plant (Hypoestes phyllostachya) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leggy, straggly growth
Caused by insufficient light or failure to pinch out growing tips. Pinch regularly and move to a brighter location.
Fading spot color
Low light causes green pigment to take over. Ensure bright indirect light to keep spots vivid.
Wilting
This plant wilts rapidly when underwatered. Check soil moisture daily in warm weather and water as soon as the top layer dries out.
Fungus gnats
Overwatering attracts fungus gnat larvae. Allow the top of the soil to dry a little between waterings and use sticky yellow traps.
Powdery mildew
Poor air circulation encourages mildew. Space plants apart and avoid overhead watering in cool, damp conditions.
