San Marzano Tomatoes – When it comes to heritage tomato plants, there’s no better place to look than right here. The San Marzano tomato is ready to satisfy your cravings! Despite the fact that the San Marzano tomato we know now is quite different from the one we knew in the past, this heritage tomato type has roots that date back to the 18th century in Italy. These squat, indeterminate plants grow to a height of 5–6 feet and are densely packed with flowers.
A seemingly limitless supply of oblong-shaped fruits weighing around 4–6 ounces apiece and containing few seeds is produced by this species. The medium-sized tomatoes, which grow in clusters of six to eight plants, are excellent for eating fresh or preserving for later use. For gardeners who want to make the most of a tiny area or patio, they’re an excellent choice.
Following your first harvest of San Marzano tomato plants, it will be clear why others have been cultivating them for hundreds of years: they are delicious. Even while the plants themselves grow to a moderate height, they certainly live up to their reputation as prolific producers.
The 2013 season saw me grow one San Marzano tomato on a patio and another in-ground at a different site, both of which had excellent results. Tomatoes thrived with incredible vigor and provided plenty of tasty fruits on both plants. It was possible to utilize the tomatoes in a variety of dishes such as sauces, soups, and even canned salsa. This essay will demonstrate to you how to produce and care for this amazing type of tomato on your own time and budget.
Instructions on How to Plant San Marzano Tomatoes
A few pointers on how to establish your own San Marzano tomato plant are provided below:
Growing Your Own San Marzano Plants From Seed: While you may buy young San Marzano plants from garden stores, growing your own from seed has several advantages. Not only will you be able to determine the age of your tomato plant, but you will also be able to determine how and where it was cultivated. When it comes to boosting yields, timing and correct seedling care are critical considerations. Plant seeds inside six to eight weeks before the typical final spring frost date to ensure a successful harvest.
If you want to grow them in containers, use the largest one that you can locate in order to maximize space. These tomato plants are putting on a lot of weight and have a strong root system to match. Small pots will simply cause the roots to constrict, resulting in a reduction in tomato yield. Grow these plants in 20-gallon pots to ensure that they have the maximum possible tomato output potential.
Even though these plants may not grow as big as other indeterminate kinds, they will still need the support of a tomato cage to ensure their survival. Choose a cage that is at least 5 feet tall in order to get the greatest possible outcome.
Full Sun: The San Marzano tomato plant, like all other tomato plants, will need at least 6–8 hours of direct sunshine every day, seven days a week. While they will grow in a little less space, the yields and the size of the fruits themselves will be significantly reduced.
Because these plants are heavy feeders, the in-ground gardener must amend the soil with plenty of compost or aged manure before planting them.The best-graded potting soil available should be used by those who grow in containers. Make certain that the soil drains adequately in any situation. Slow-draining soils may suffocate tomato roots, resulting in rotting.
How to Grow and Care for San Marzano Tomatoes
Growing San Marzano tomatoes will be a breeze for even the most inexperienced gardeners. All indeterminate tomato types will need the same basic care, with the exception of being a little bushier than most other indeterminate kinds. You won’t want to miss out on any of these useful suggestions:
Regular pruning is necessary because, as the tomato plant develops during the season, there will be numerous interior branches that get shaded by the sun on a regular basis. The leaves on these branches will begin to yellow and perish as time passes. Branches that have gone yellow on half their length may be clipped off. Keep up with the frequent trimming of old branches and suckers to ensure appropriate ventilation is kept in place.
Ensure that the plant is well supported. Even with a tall tomato cage, there will be some branches that break away. Any stray branches should be tied together and held with a soft rope to prevent them from falling.
When transplanting San Marzano tomato plants to their ultimate outdoor site, consider adding some slow-release and organic nutrition into the soil around the plants’ roots to help them thrive. Each transplant will benefit from a small fish carcass or a quarter cup of bone meal placed below the roots for a few months, providing consistent nutrients for the plant. Because both the fish and bone meal are heavy in phosphorus, they will have a significant impact on tomato output later in the season, especially if used together.
Keep in mind that if you decide to move the plant outside, the fruit should be ready in 70–80 days.
Potential Diseases and the Treatments for the Plants
While you have healthy and blooming garden soil, it is unlikely that you will have any problems when planting San Marzano tomato plants. Things, on the other hand, may go awry if your soil has been affected by illness or nutritional deficiencies. If you’ve ever had problems with the quality of your soil, pay close attention to the information provided below.
Soil-Borne Wilts: Open-pollinated and heritage varieties of the San Marzano tomato plant are less likely to be resistant to soil-borne wilts such as Verticillium wilt and Fusarium wilt than hybrid and cross-pollinated types. If certain bacterial illnesses are known to be prevalent in garden soils, do not grow San Marzano tomatoes in such soils. If plants get infected with Verticillium or Fusarium wilts, the sick plant should be removed and disposed of. Planting in the same location should be avoided for at least 3–5 years. In certain cases, resistant bacterial wilts in San Marzano hybrids have been bred into the lineage of the cultivar.
Blossom End Rot: Blossom end rot may develop in San Marzano tomato plants, just as it does in most other big tomato plants. According to popular belief, a shortage of accessible calcium in the soil is the root cause of this browning of the tomato fruit’s tip. As a preventive precaution, incorporate lots of eggshells or bone meal into the soil at the start of the season to help it retain moisture. Watering at regular intervals might also be beneficial in the fight against blossom end rot in tomatoes that are already infected.
