Two to five seeds should be placed in each container, with a maximum depth of 0.4” (1 cm), subsequently leaving one or two plants per container, keeping only the most vigorous plants. Repotting is carried out when the seedlings reach a size of 6” to 10” (15 to 25 cm), generally repotting up to the stem to give the appearance of having longer roots.

The recommended spacing in terms of how to plant tomatoes can vary according to the variety grown and growing conditions.

Dwarf plants can be planted 12” (30 cm) apart.

How to Care for Tomato Plant

Many tomato varieties have indeterminate growth and need to be grown by staking. This process should be done by tying the plant to a fence, X-shaped rods, or pergolas, every 10 to 15 days. The minimum height for tying is 5 ft (150 cm) (generally this is done at 6.5 ft (2 m). On these plants, flowers and fruit can be seen to appear continuously along the branch, which is why those side shoots can be removed weekly to maintain linear growth until the plant reaches the maximum height of the support.

For those tomato crops with a certain growth, this process is not necessary, nor should the lateral shoots be removed since the new branches are the ones that produce flowers and fruits. These plants are more compact and branched.

The care for crops with intermediate growth characteristics is the same as those used for plants with indefinite growth.

Finally, an important step in planting tomatoes is to remove all invasive plants that compete for resources and nutrients.

Tomato Harvesting

The start of the harvest depends on the type of tomato used and the growing conditions. Generally, tomatoes are harvested at 7 to 8 weeks after planting, but there are also crops where this occurs at 10 to 16 weeks (usually large crops).

Fruits should be harvested when fully ripe, as the sugar concentration will be higher if the fruit remains on the plant until fully ripe.

Tomato plants are perennial, which is why if living conditions are suitable they can produce fruit for a few years, although this is far from the reality since in commercial plantations they are only grown for a few months.
