Frequently asked questions
When do you sow lettuce?
Indoors from March-May (for early crops); into the bed direct sow april-august, in small successions.
When are lettuce ready to harvest?
May-September, in a typical year for this climate.
Do the lettuce 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.
