Growing habits

The growing habits of San Marzano tomato plants are an important factor in their cultivation and success. These plants are known for their indeterminate growth habit, meaning they will continue to grow and produce fruit until killed by frost or disease. This growth habit makes them well-suited for staking or caging, as they will need support to grow vertically. San Marzano tomato plants can grow to be quite large, so it is important to provide them with adequate space in the garden.

The growing habits of San Marzano tomato plants also affect their fruit production. Indeterminate tomatoes tend to produce fruit over a longer period of time than determinate tomatoes.

  San Marzano tomato plants exhibit structural defenses such as a thick cuticle and trichomes (small hairs) on their leaves and stems. These physical barriers help to deter pests and pathogens from entering the plant.

• Biochemical Defenses

  San Marzano tomato plants produce a range of biochemical compounds that possess antimicrobial and antifungal properties. These compounds can inhibit the growth and spread of pathogens within the plant.
