San Marzano

Growing from seed

Start San Marzano indoors about 8 weeks before your last frost, keeping seeds in warm soil (around 20–25 °C). Seeds usually come up in around 7 days. Move seedlings out once the danger of frost has passed, in full sun, spaced about 60 cm apart. Expect to harvest in roughly 80 days.

Keep track of the seeds you own.
