When to plant beetroot in Łódź

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 cautious column is calculated from the latest frost recorded in the period (11 May). Use it for tender crops you cannot re-sow.
The year in Łódź
What can move the date
Each "seed" is a cluster of several, so thin ruthlessly to one seedling every 10 cm. Boron-hungry: brown, corky patches inside mean a deficiency, not a disease.
Final spacing: 10 × 30 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.
