Squash plants grow very quickly and put on a mass of foliage as they develop. These large leaves can turn yellow for various reasons, but what causes discolored foliage and how worried should you be about it?
The usual suspects for squash leaves turning yellow are related to watering, nutrients, pests, and diseases. Though yellow leaves can also just be a sign of plant aging. If you are growing squash, or growing pumpkins also, then you need to be vigilant to spot yellowing leaves and take prompt action.
