Safety Warnings

Cold frame — Ventilated structure for ripening

Straw — Dry bedding for fruit(as needed)

Monitor the weather for the first upcoming frost in October.

Tip: Picking mature or nearly mature fruit before the frost prolongs the season.

Pick all mature and nearly mature tomatoes from the vine.

Tip: Do this immediately when the first frost is expected.

Place the unripe or nearly mature tomatoes on a bed of straw inside a cold frame.

Tip: Straw provides a cushion and insulation for the fruit.

Cover the fruit with additional straw and secure the sash to protect them from frost.

Tip: The sash acts as a barrier against extreme cold.

Maintain ventilation within the cold frame while the fruit ripens.

Tip: Proper airflow is critical; otherwise, the tomatoes will rot instead of ripening.

Allow the tomatoes to ripen in the cold frame over several weeks.

Tip: Check regularly for peak ripeness.

Unripe tomatoes can be successfully ripened after harvest if kept in a ventilated cold frame with straw.
