<human>: How could I know if a tomato is ripe or not?
<bot>: You can check the color of the tomato. If it’s bright red, it’s likely to be ripe. 2 Another way is to give it a gentle squeeze. A ripe tomato should feel slightly soft and yield slightly when you do this. 3 You can also look at the stem end of the tomato. If it has turned from green to yellow, it’s probably ready for harvest. 4 Finally, taste the tomato. It should have a sweet flavor with a slight tartness.
