Tomato harvesting: Tips for ripening green fruit indoors

Horticultural experts suggest that tomatoes do not always need to remain on the plant until they turn red to reach full maturity. For tomatoes that have reached their full size but remain green, harvesting them at the 'mature green' stage can allow them to continue ripening indoors.

Key indicators for harvesting include the 'breaker stage,' where color changes begin to appear on the skin, signaling the production of ethylene. To ensure proper ripening, tomatoes should be kept in a stable, moderate temperature environment, ideally between 18 and 21°C. Experts warn that extreme heat, specifically temperatures above 29°C, can actually slow the ripening process.
