How To Grow Salsa in Pots – Tomatoes

Arguably, no crop in the garden is more anticipated than the first fresh, vine ripened tomato of the season. Many hybrids have been bred to mature early, but tomato lovers often find these have little more flavor than do supermarket tomatoes.

As a rule, bush or determinate tomatoes will do better in a container because the plants will tend to stay smaller. Most determinate tomatoes produce all of their fruit over a short period of time, such as within two weeks, and then stop producing. Determinate tomatoes are easier to grow since they do not need as much pruning as indeterminate tomatoes.

How to Choose Tomatoes to Grow in Containers

If your goal is to make fresh salsa all season long, you can either choose several varieties with different maturation days, or plant additional plants according to a schedule such as once a month. Keep your first fall frost in mind when timing your last planting so that your efforts will not be made futile by the onset of frost.

Tomatoes generally fall into four classification for their maturation date: ultra early, early, mid season, and late season. Ultra early tomatoes mature in about 50 to 60 days, early in 61 to 70 days, mid season or main season in 71 to 80 days, and late season in 81 or more days. This classification varies by grower, and for tomatoes is always stated in days from transplant, not including the 6 to 8 weeks to grow the seeds into baby plants ready to transplant. Warmer weather, especially nights, will help to ripen tomatoes faster, while cooler weather will slow down tomato ripening.

Choose very large containers to give tomato plants’ large root systems plenty of room, at least 10 gallons. When growing tomatoes in containers in hot areas, a mulch of light colored rocks will help keep the soil cooler. Tomatoes tend to slow down or stop producing when the soil is over 80°F.

You can further extend your growing season by planning ahead for tomato varieties that are known for ripening well after they are picked or that make good sun-dried tomatoes, and by protecting tomatoes from the first few frosts with makeshift tents. About 30 days before your first frost, top off the vine by cutting the main stem just above the last set of fruits. This may seem harsh, but it will force the plant to put its energies into ripening developed fruit.

Tomatoes that make good paste tomatoes also make good salsa tomatoes since they have a meatier, less juicy texture. You can use any tomato variety for salsa, but if you choose a juicier variety and prefer a thicker salsa, you may want to drain them after you have chopped them and before you add them to other ingredients.
