As the calendar turns to September, our attention turns to winter squash. Once they're planted, winter squash tend to take care of themselves. The squash start sizing and coloring up this time of year and due to this year's hot temperatures, it seems pumpkins and winter squash are maturing early. They can stay in the garden until you're ready to harvest. If you can’t easily pierce the rind with your fingernail, it's best to wait until the vines die back to harvest.
