Yellow Squash Turning Green: Variety Trait, Not Problem

Normal Color Progression

Some yellow straightneck varieties start green, develop green stripes, then fade to yellow. This is genetic, not a nutrient issue.

Excess nitrogen delays color change. Use balanced fertilizer (5-10-10), not high-N lawn food.

Pick at 6–8" regardless of color. Flavor and texture peak then. Overmature = tough, seedy.
