How long does it take for tomatoes to turn red?
Also asked, how do I get my tomatoes to turn red?
Tomatoes are triggered to turn red by a chemical called ethylene. Ethylene is odorless, tasteless and invisible to the naked eye. When the tomato reaches the proper green mature stage, it starts to produce ethylene. The ethylene then interacts with the tomato fruit to start the ripening process.
Likewise, do tomatoes get bigger after they turn red? Nope, tomatoes reach full size while they are stilll green, which is why people think it takes forever for them to ripen. Once they start to change color they are effectively cut off from the plant sap by scar tissue in the stem so the plant has nothing to do with their ripening.
Similarly, you may ask, how long does it take for cherry tomatoes to turn red?
20 to 30 days
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.
