Know before you buy
Determinate tomatoes grow to a fixed size and ripen their entire crop within a concentrated window of about a month. This makes them an excellent choice if you plan to do a large batch of canning or sauce making all at once.
No, these are not recommended for containers. They require the space and stability of a garden bed to support their growth and yield.
You can expect to harvest these tomatoes approximately 75 days after transplanting your seedlings into the garden.
San Marzano tomatoes have thick walls and minimal juice, which reduces the amount of time you need to spend boiling down your sauce. Their meaty texture and low water content provide the ideal consistency for authentic Italian-style sauces.
For the best results, plant the seeds 1/4 inch deep in soil kept between 70-80°F. Ensure they have access to full sun once they sprout to encourage healthy, vigorous growth.
