Too much sun or a feeding gap

What's happening

New fronds bleaching to a pale, washed-out yellow on the window side points to too much direct sun scorching tender growth — parlor palm is an understory plant and burns easily. Pale, weak new fronds with no recent feeding instead point to a nutrient shortfall, since the youngest growth shows a lack of food first.

How to fix it

Move the plant out of any direct sun into the bright, indirect or even medium light parlor palm prefers. If feeding is overdue, start a balanced liquid fertilizer at half strength through the growing season. Fronds that emerge after the change should come in a healthy green.

This is general guidance based on common symptoms; individual plants vary.
