Why won't my tomatoes ripen on the vine?

With so many tomatoes on the vine, the leaf surface area has a hard time keeping up with the demands of the fruit. Heat also explains why fruit stops ripening. Tomatoes stop making the pigments carotene and lycopene at temperatures higher than 85 degrees.

In this way, why are my tomatoes not turning red on the vine?

Tomatoes won't turn red if it's too hot (above 85F) or too cold (below 50F). Also, as tomato plants mature through the summer, they can become huge and overgrown. When that happens, they tend to spend most of their energy on growing leaves and flowers, rather than ripening tomatoes.

One may also ask, how do you turn green tomatoes red? One way how to turn green tomatoes red is to ripen mature green tomatoes in a well-ventilated area at room temperature, checking their progress every few days and discarding unsuitable or soft ones. The cooler the temperature, the longer the ripening process will take.

Beside above, how can I make tomatoes ripen faster?

If you want to speed up ripening even more, place the tomatoes in a paper bag with a slice of banana or apple. Tomatoes produce a gas called ethylene when ripening that expedites the ripening process. The fruit slice will give off ethylene gas as it rots, helping to speed up the ripening of the tomatoes.

Do Tomatoes need sun to ripen?

The optimum temperature for ripening tomatoes is 70 to 75F. Tomatoes do not require light to ripen and in fact, fruit exposed to direct sunlight will heat to levels that inhibit pigment synthesis. Direct sun can also lead to sunscald of fruit. Do not remove leaves in an effort to ripen fruit.
