Growing San Marzano Tomato Seeds.
To enjoy the delicious flavor and vibrant taste of San Marzano tomatoes, you can grow them from seeds. Follow these steps to successfully plant and nurture your San Marzano tomato seeds.
- Start Indoors: Begin by starting your San Marzano tomato seeds indoors, approximately 8 weeks before the last frost date in your area. This allows enough time for the seeds to germinate and develop into healthy seedlings.
- Sow the Seeds: Sow the San Marzano tomato seeds in a seed starting medium. Make sure the soil is moist and maintain a temperature of 70 to 80 degrees Fahrenheit. This optimal temperature encourages germination and healthy plant growth.
- Transplanting: Once the seedlings reach a height of 6 to 12 inches, it’s time to transplant them into a larger pot or the garden bed. When doing this, bury at least two-thirds of the stem. Planting the seedlings deep promotes the development of a strong root system, which is essential for healthy and vigorous plants.
- Provide Support: San Marzano tomato plants tend to grow tall and heavy with fruit, so it’s important to provide them with adequate support. Use a trellis or stake to prevent the plants from falling over as they grow. This support ensures that the plants remain upright and helps them distribute their weight evenly.

Fertilize them with a balanced 5-10-10 fertilizer or a water-soluble tomato fertilizer, following the manufacturer’s instructions. Apply the fertilizer during transplanting and periodically throughout the growing season.
By creating an environment that meets these ideal conditions, you’ll give your San Marzano tomato seeds the best chance to flourish and produce delicious, organic tomatoes.

Harvesting and Storing San Marzano Tomatoes.
After patiently nurturing your San Marzano tomato plants, it’s time to reap the rewards of your hard work by harvesting and storing these delicious tomatoes. Here’s how you can ensure the best flavor and longevity for your San Marzano tomatoes.
San Marzano tomatoes typically ripen within 78 to 85 days after transplanting. When the fruits are large and slightly green and yellowish, they are ready to be harvested. To do so, simply twist the stem gently or use clippers to detach the tomatoes from the plant.
If you accidentally pick the tomatoes too early, don’t worry! You can allow them to ripen off the vine by placing them in a paper bag. The trapped ethylene gas will help speed up the ripening process, allowing the tomatoes to develop their full flavor.
Interestingly, San Marzano tomatoes can continue to ripen even after being picked. This is why it’s essential to check your plants regularly and harvest the ripe tomatoes to avoid overripening or loss of flavor.
Once you have harvested your San Marzano tomatoes, it’s time to focus on storing them properly to extend their shelf life. Ripe tomatoes should be stored in a cool, dry place. If you prefer, you can also store them in the refrigerator to help slow down the ripening process.
To save San Marzano seeds for future planting, it’s crucial to allow the tomatoes to fully ripen on the vine. This ensures that the seeds are mature and viable. Once the tomatoes have ripened, extract the seeds and dry them thoroughly before storing them in a cool, dry place.

Propagation and Pruning of San Marzano Tomato Plants.
When it comes to propagating San Marzano tomato plants, stem cuttings offer an easy and effective method. To propagate the plants, I recommend taking stem cuttings and rooting them in a potting mix. Simply select a healthy stem, around 4-6 inches in length, and remove any leaves from the bottom half. Place the stem in a soilless potting mix or a combination of peat moss and perlite. Keep the soil moist and provide indirect light until roots develop, which usually takes about 2-4 weeks.
Pruning is an important aspect of maintaining healthy and productive San Marzano tomato plants. Removing unwanted shoots and suckers helps concentrate the plant’s energy towards fruit production and promotes better airflow. I suggest regularly checking for suckers that develop in the “V” between the main stem and branches. These suckers can be pruned to direct more energy to the main stem and encourage larger and tastier fruits.
If you’re growing indeterminate varieties, pruning can also help control the plants’ growth and prevent overgrowth. It’s important to monitor the height and spread of the plants, ensuring they stay manageable and don’t overcrowd other plants in your garden. Regularly check for branches that may be touching the ground or hanging too low, as they can be pruned or supported to maintain a neat and organized growth pattern.
Pruning San Marzano tomato plants not only contributes to their overall health but also encourages the development of robust fruiting clusters. By removing unwanted growth and maintaining proper spacing, you’ll promote better air circulation and minimize the risk of diseases. Remember, a well-pruned San Marzano tomato plant is a happy and productive plant.
Overall, proper propagation and pruning techniques are essential for the successful growth of your San Marzano tomato plants. By following these guidelines, you can ensure healthy root development, maximize fruit production, and enjoy a bountiful harvest of delicious tomatoes. Now that you have the knowledge, it’s time to put your green thumb to work and watch your San Marzano tomato plants thrive.
