How to grow san marzano tomatoes

The best way to grow San Marzano Tomatoes is by starting them in a seed tray, then transplanting them into larger containers when they’re big enough.

Although they can be grown in the ground, root disturbance and damage caused by hoeing or weeding can seriously affect the crop yield.

Place the seed tray in a warm, sunny spot and keep the compost moist until germination. Once the plants have outgrown their seed tray, you can transplant them into large pots or grow bags which you should place on a sunny patio or decking area.

You can feed the tomatoes with a high potash liquid feed every two weeks to encourage good flowering and fruiting.

Harvest when tomatoes turn red on the vine, then allow them to ripen further off the vine for maximum flavor.

When to plant San Marzano tomato seeds 

After the last frost, the best time to plant San Marzano tomato seeds is in spring. Since San Marzano tomato plants grow 4 feet tall, they need to be supported with stakes or cages.

You generally want to plant your tomatoes when the soil temperature is between 65 and 70 degrees Fahrenheit, which is usually a week or two after the last frost date in your area.

The ideal soil pH for growing tomatoes is between 6.2 and 6.8, but tomatoes will tolerate a pH as low as 5.5. For comparison, an average of 5.7 would be considered neutral (neither acidic nor alkaline). Contact your local agricultural extension office if you need help testing your soil and making adjustments.

The first step in planting San Marzano tomato seeds is to decide whether you want to start the tomato plants indoors and transplant them later or plant them directly in the ground. If you are going to be starting your San Marzano tomato seeds in a greenhouse or indoors, you will need to give the tomato seeds time to germinate and grow before being transplanted outdoors. To do this, plant the seeds indoors 6-10 weeks before the last frost of winter. You can start them by planting the San Marzano tomato seeds directly into a seed tray filled with a seed starting mix or by soaking them overnight in water and then planting them in a cup of soil. In either case, cover the San Marzano tomato seeds with about ¼ to ½ inch of soil and keep them at about 70 degrees Fahrenheit for best results. The plants should begin to sprout within four days.

If you decide to plant your San Marzano tomato seeds directly in the ground, you will have to wait until all danger of frost has passed. Once that time comes, plant your San Marzano tomato seeds directly into the ground or a container and cover them with just ¼ inch of soil, just like you would if you were starting them indoors.
