Frequently asked questions
When do you sow zucchini?
Indoors from April-May; into the bed plant out early june.
When are zucchini ready to harvest?
July-September, in a typical year for this climate.
Do the zucchini dates change with the weather?
Yes — the window follows the frost dates of your plot. A coastal garden runs a week or two earlier; an inland frost pocket later. The published windows are the reference, your soil thermometer is the truth.
