Growing Squash

What does it mean when the squash leaves are turning yellow? Too much watering?


ANSWER:

Generally, squash leaves turning yellow is a sign of plant stress.

The stress can be from too little water (they need about 2" a week), a pest called "vine borers", an iron deficiency caused by over-watering, or a disease called "Bacterial Wilt".

If you suspect that you have been over-watering, I would recommend that you lessen the amount of water to about 2" per week, and apply some fertilizer that includes chelated iron.
