Growing & care

Transplanting and caring for tomatoes outdoors involves a few essential steps. First, choose a sunny location with well-drained soil. Prior to transplanting, harden off the seedlings by gradually exposing them to outdoor conditions. 

Dig a hole slightly larger than the root ball of each seedling and plant them, burying the stem up to the first set of leaves. Water the seedlings thoroughly after transplanting. Provide consistent watering, aiming for 1-2 inches of water per week. 

Stake or cage the plants for support and prune indeterminate varieties by removing suckers. Monitor for pests and diseases, taking prompt action if necessary. By following these steps, you’ll set your tomato plants up for healthy growth and a fruitful harvest.

Common problems

Costoluto Genovese is a popular tomato variety known for its beautiful ribbed shape and rich, sweet flavor. However, like any other tomato variety, it can be prone to certain problems that can affect its growth and yield. Here are some of the common problems you may encounter when growing Costoluto Genovese tomatoes, and what you can do to address them:

  1. Blossom End Rot: This is a common problem in tomatoes and is caused by a calcium deficiency. Blossom end rot appears as a dark, sunken spot at the bottom of the fruit. To prevent this, make sure your soil is rich in calcium, and avoid overwatering your plants.
  2. Cracking: Costoluto Genovese tomatoes are prone to cracking, especially if they are not harvested in time. Cracking can also occur due to inconsistent watering. To prevent this, make sure to water your plants regularly and harvest your tomatoes as soon as they are ripe.
  3. Blight: Blight is a fungal disease that can affect tomato plants, causing the leaves to turn yellow and wilt. To prevent blight, make sure to space your plants properly, and avoid watering them from above. You can also apply a fungicide to protect your plants from blight.
  4. Tomato Hornworm: These large green caterpillars can be a big problem for tomato plants, as they can quickly devour the leaves and fruits. To prevent tomato hornworms, try planting companion plants like marigolds or basil, which can repel these insects. You can also handpick the caterpillars and remove them from your plants.
  5. Fusarium Wilt: This is a fungal disease that can cause the leaves to turn yellow and wilt, eventually leading to the death of the plant. To prevent fusarium wilt, make sure to rotate your tomato plants every year, and avoid planting them in soil that has previously been infected with this disease.

In conclusion, growing Costoluto Genovese tomatoes can be a rewarding experience, but it is important to be aware of these common problems and take steps to prevent them. With proper care and attention, you can enjoy a bountiful harvest of these delicious and beautiful tomatoes.
