San Marzano tomatoes can be harvested when they are large and their color is green and yellowish. Like most tomatoes, it will continue to ripen once harvested. You can also let San Marzano tomatoes fully ripen on the vine, but I personally prefer to harvest them a little earlier.

How To Ripen Green Tomatoes From The Plant
One of the ways to ripen green tomatoes off the plant is to put the unripe tomatoes and a ripe banana in a paper bag, several sheets of newspaper, or in a cardboard box, closed in a warm place away from sunlight.
The banana generates ethylene gas, a phytohormone responsible for fruit ripening. That is why green tomatoes will ripen faster. It is advisable to check the paper, replace it if necessary, and replace the banana if it is too ripe.
How to Harvest San Marzano Tomatoes

If you have several San Marzano tomato plants, you can get enough tomatoes to prepare, for example, a sauce. But you can store them if you don’t have enough tomatoes simultaneously.
Wash the tomatoes, chop them, and store them in the freezer. You can prepare soups, stews, or fillings for tacos with these tomatoes. Because the texture is not the same as fresh tomatoes, it is recommended for these types of dishes.
Another way to store San Marzano tomatoes if you have too many is to dehydrate them. Use a dehydrator or dry them in the sun. Personally, I prefer to use the dehydrator. Every year I prepare many dehydrated tomatoes that I use as a snack.
