How do you know when it is time to harvest summer squash? - Marilyn

ANSWER: Summer squash should be harvested when they are still immature, which is before the skin and seeds have toughened. Leaving them on the plant too long will sap the strength of the mother plant, and more importantly the fruit would be tough. Generally the long varieties should be harvested at 6-8 inches long, or 2 inches in diameter. Patty pan types should be harvested at about 2-3 inches in diameter. Summer squash develop quickly, so frequent picking will be in order. Here is the link to the KSU bulletin on Squash. Carole - Johnson County Extension Master Gardener
