Squash - Illinois Vegetable Garden Guide - University of Illinois Extension



Squash has about the same cultural requirements and problems as pumpkins, cucumbers, and muskmelons.

Squash varieties are divided into three classes - summer, fall, and winter. The summer squashes are used while they are young and tender, when the rind can be easily penetrated by a thumbnail. The fall and winter varieties have a hard rind, are harvested when mature, and are good for storage. Store winter squash the same as pumpkins.


Common insects on this crop and pumpkins are cucumber beetles, squash bugs, and squash vine borers, which can be controlled with a general garden insecticide.
