1. Plant outside once nighttime temperatures are consistently 60 degrees. Space plants 18" apart in well-drained soil in full sun.
2. Till soil 8-10" deep and cover with dark mulch about a week before planting to warm the soil. Mulch will also help maintain moisture throughout the growing season.
3. Water regularly, one or two inches of rainwater or irrigation per week. Supplement rainwater by watering at the base of the plant in dry weather. Water thoroughly once or twice a week to give the roots plenty of consistent water and help prevent cracking on fruits.
4. Cage tomato plants or tie them loosely to a stake. Trim side shoots and prune plants to encourage fruit-bearing branches to flourish. Remove the bottom 6-10" of leaves once the plant has reached 12" tall or more to prevent disease and keep fruit from touching the ground.
5. Harvest tomatoes throughout the season once they are ripe. Just before frost, pick all the almost-ripe fruits and ripen them on a newspaper at room temperature. Store tomatoes temporarily at 50-60 degrees. Don't refrigerate them. For long-term storage, freeze or can any variety.

Coach Your Customer: Pests can attack tomato plants in the garden, most notably nematodes and tomato hornworms. Plant tomatoes in a different location every year, especially if nematodes have eaten the roots of your plants in the previous year. Marigolds often repel nematodes planted alongside tomatoes. Look out for tomato hornworms, large green caterpillars that eat the foliage. Remove them by hand to a bucket of soapy water. If the hornworm is covered in white spots, leave the worm and eggs on the plant. Those white spots are wasp eggs that parasitize the hornworm and benefit your garden.
Disease
Tomatoes aren't prone to disease but root rot can develop in overly wet conditions. Water at the base of each plant in the morning, allowing the soil to dry between waterings. Provide good airflow in your greenhouse and space containers so air and sunlight can reach the base of each plant.
Planting Tomato San Marzano (Roma) Liners
We recommend planting one seedling per 1801-cell or 4-inch container. Use well-drained soil and center the seedling in the container. Cell packs finish in 2-3 weeks.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
