Follow These Planting And Growing Tips To Succeed:

#1 – Purchase San Marzano seed or seedlings from a well-established source. Be certain you are buying a heritage type tomato, not a hybrid.

#2 – Plant San Marzano seedlings early. You should begin approximately two months before the date of your last predicted frost. Be sure to use a high-quality potting soil with fish meal and compost added.

#3 – Start your seedlings in a reliably warm environment and keep the soil lightly moist at all times. Covering the seedlings with a transparent cover can help produce these conditions.

#4 – If you sow seedlings over a single surface, thin them to approximately two inches apart after the appearance of the second set of leaves. If you planted them two or three seeds per small peat pots, allow the strongest to remain and remove the weaker plants.

#5 – Approximately a week after the final frost of winter, begin acclimating the seedlings to the outdoor environment. Let them stay outside for a few hours during the warmest part of the day for a couple of weeks.

#6 – When the plants reach a height of six inches, transplant them in full sun to the garden or their permanent containers. Be sure the soil contains these components:

#7 – Set the seedlings, so the top set of leaves is two or three inches above the soil level. Remove the lower leaves of the plant, leaving the top leaves in place. Fill in around the seedling with your amended soil and pack it in firmly by hand.

#8 – Create a moat around each plant for watering. Keep the plants well-watered, but never allow them to become soggy. Watering a couple of inches a week should be perfect for garden plants. If you have planted in containers, you will need to monitor and water as needed closely.

#9Provide your tomatoes with support by using a tomato cage or poles. Secure them carefully using strips of pantyhose which will hold them in place without damaging stems.

#10 – Watch out for blossom end rot and horn worms. Pick tomato hornworms off whenever you see them and check the undersides of your tomato plants’ leaves where horn worms love to hide.

Patience & Persistence Pay Off!

You should have some good San Marzano tomatoes approximately three months after planting your seedlings. Pick them when they feel slightly soft when squeezed.

You should be able to harvest some tasty tomatoes until the first frost. Just before the first frost, gather your green tomatoes and let them ripen indoors. Now enjoy all the full tomato flavor, in sauce and salads.
