Dealing with Green Tomatoes

October and it is high time all those tomatoes were picked off the vines in the greenhouse, regardless if they are still green. Tomatoes need a constant overnight temperature of 15.5 °C for proper growth and ripening. Lower temps sustained for longer than a week will cause growth problems, such as splitting, and delay ripening.

Green tomatoes can still be rescued and ripened indoors for fresh eating through the winter. One of the best methods is to place them in a single layer in newspaper-lined beer flats and cover them with a couple of layers of newspaper to keep them in the dark. (Tomatoes can be stacked two to three layers high if you are using deeper boxes, as long as you keep the heavier tomatoes on the bottom, and cover each layer with newspaper. However, for ease of regular checking for ripe tomatoes, the beer flats really work much better. And they stack wonderfully if you place each flat crosswise to the previous flat.)

Place the flats of green tomatoes in an unheated basement, or somewhere where it is relatively cool. Some people use their 2nd fridge but the tomatoes should really be kept at a slightly warmer temp than 4 °C.

Be sure to check through all of the flats on a weekly basis for ripened fruits. Such a treat in the middle of winter. So full of flavour.
