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 (10 May). Use it for tender crops you cannot re-sow.
The year in Berlin
What can move the date
Sow when the soil holds above 10°C — late summer beats spring, because the grass establishes without competing against germinating weeds. Rake to a fine tilth, sow at 30–35 g per square metre, and keep it damp for three weeks.
Final spacing: 0 × 0 cm. Soil: pH 6–7.
