Frequently asked questions
When do you sow cucumbers?
Indoors from April; into the bed plant out early june, after the last frost.
When are cucumbers ready to harvest?
July-August, in a typical year for this climate.
Do the cucumbers 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.
