When to plant broccoli in Kraków

The Kraków dates are calculated from the observed last spring frost — a 2016–2025 mean of 16 April — rather than from a latitude estimate or a national calendar. The frost-free season here averages 196 days.

Season anchorobserved 2016–2025

Last spring frost: 16 April · latest 11 May

First autumn frost: 29 October · earliest 4 Oct

Frost-free season: 196 days · 10 complete years

These come from the ERA5 reanalysis on a roughly 9 km grid, so they describe the area rather than your plot. A hollow, a frost pocket or an exposed site regularly runs several degrees colder, so use the cautious date for a decision you cannot undo.

The year in Kraków

What can move the date

Any check — dry soil, root disturbance, a heat spell — makes it button up and flower tiny. Keep it watered and firm the soil around the stem well.

Final spacing: 45 × 60 cm. Soil: pH 6.5–7.5.

Direct-sow only once the soil holds 7°C or more — soil temperature decides germination, not the date.
