Question 1

How tall do San Marzano tomato plants grow?

Accepted Answer

As indeterminate plants, San Marzano tomatoes continue to grow throughout the growing season, typically reaching a height of 4-6 feet, though they can grow even taller in favorable conditions. Staking or caging is recommended to support the plants as they grow and bear fruit.

Question 2

Can I grow San Marzano tomatoes in a pot?

Accepted Answer

Yes, you can grow San Marzano tomatoes in pots, but be sure to choose a pot that's large enough to accommodate the plant's growth—typically a pot with at least a 5-gallon capacity. Ensure the pot has good drainage and use a high-quality potting soil.

Question 3

Why are my San Marzano tomatoes cracking?

Accepted Answer

Tomato cracking often happens due to fluctuations in watering. If the plant gets too dry and then is suddenly watered heavily, the interior fruit may absorb water and expand faster than the outer layer can grow, leading to cracks. Maintain consistent watering to prevent this issue.

Question 4

When should I prune my San Marzano tomato plants?

Accepted Answer

It's best to start pruning when the plants are fairly young, around 12-18 inches tall. Remove the small shoots that appear in the "V" between the main stem and the branches. Continue to prune as needed throughout the growing season to improve airflow and reduce the risk of diseases.
