A tomato plant that has had sufficient sunlight, water, and nutrients will not be the same as one that has had a nutrient deficiency.
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. Once you harvest your first San Marzano tomatoes, watch the plant daily to harvest the remaining tomatoes. Not all tomatoes will be ripe at the same time.

How to Harvest San Marzano Tomatoes
To harvest San Marzano tomatoes, I recommend not pulling the tomatoes from the plant to avoid damaging them. As not all tomatoes will ripen at the same time, it is important not to damage the plant so that it continues to produce tomatoes.
Use scissors or a knife to harvest San Marzano tomatoes. Before using the tools, disinfect them with alcohol to avoid transmitting diseases to the tomato plants. If you harvest a tomato that is still too green do not worry, place it in a paper bag for a few days to ripen a little more.
A San Marzano tomato plant can produce many fruits, but not all of them will be ripe at the same time. It is best to have several tomato plants to be able to get a good number of tomatoes at the same time and to be able to make a lot of sauce or dishes.
San Marzano Tomato Harvest Time
Harvest time for San Marzano tomatoes is approximately 75 to 90 days. This means that if you plant your San Marzano tomato plants in March you can be harvesting San Marzano tomatoes in June. I repeat that the ripening days of tomatoes can vary due to climatic conditions and soil nutrients.
How to Store San Marzano Tomato
If you have several San Marzano tomato plants you can get enough tomatoes to prepare for example a sauce. But if you don’t have enough tomatoes at the same time, you can store them.
Wash the tomatoes, chop them, and store them in the freezer. With these tomatoes, you can prepare soups, stews, or fillings for tacos. 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 a good number of dehydrated tomatoes that I use as a snack.
