Tomatoes and cucumbers in an unheated greenhouse
Unheated greenhouse timing for tomatoes and cucumbers by Estonian climate region, plus frost and heat thresholds and a live next-7-days risk read from MET Norway when available.
Hiiumaa, Saaremaa ja läänerannik — mereline kliima, kevad võib hilineda. Mere mõju hoiab ööd kevadel jahedamad; soojalembeste kultuuride istutus tihti paar päeva hiljem kui sisemaal.
Frost and heat thresholds
- ≤ 2.0 °C night frost risk — cover, close vents, delay planting.
- < 8.0 °C nights too cool for reliable tomato/cucumber planting.
- ≥ 30.0 °C day heat — vent, shade, water early.

The (climate twin) mark means the date comes from a climate twin: a region abroad with a comparable growing climate (e.g. Minnesota/US), because Estonian-sourced data for that crop is not available yet. Treat it as a guide and check it against local experience. Estonian-sourced dates have no mark.
