Personal data: the calendar runs entirely in your browser; nothing you type is sent to us. Visits are counted with Cloudflare Web Analytics, without cookies, as aggregated statistics. See the privacy page.

Content: texts drafted with the help of an AI tool and checked against the sources cited on each page. Information is provided for general guidance only: see the disclaimer. Texts and drawings © 2026 SowClock. Quotations remain the property of their authors.

A friendly guide, not a guarantee. Frost dates are averages of past weather, not forecasts: a frost can come later than the average in any year. Crop timings are general rules from university extension services; your soil, microclimate, variety and the weather on the day matter too. Check your local forecast before planting out tender plants.
