How to start German Johnson tomatoes from seed
Starting tomatoes from seed is a cost-effective and rewarding way to grow your own tomato plants. To begin, choose the tomato varieties that suit your preferences and growing conditions.
Fill seed trays or pots with a lightweight and well-draining seed starting mix, plant the seeds at the recommended depth, and provide adequate moisture and warmth for germination.
Once the seedlings have developed their second set of true leaves, they can be transplanted into larger containers or individual pots. Gradually acclimate the seedlings to outdoor conditions before transplanting them into the garden.
By following these basic steps, you can successfully start tomatoes from seed and enjoy a thriving crop of homegrown tomatoes.

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
German Johnson tomatoes are a popular heirloom variety known for their large size, juicy flesh, and sweet flavor. However, like any tomato plant, they can be susceptible to a range of problems that can affect their growth and yield. Here are some common problems you may encounter when growing German Johnson tomatoes:
- Blossom end rot: This is a common problem that affects many tomato varieties, including German Johnson. Blossom end rot is caused by a calcium deficiency in the plant, which leads to black, sunken spots on the bottom of the fruit. To prevent this problem, make sure your soil is rich in calcium and keep the plant consistently watered.
- Fusarium wilt: This is a fungal disease that can cause wilting and yellowing of the leaves, stunted growth, and poor fruit production. Unfortunately, there is no cure for fusarium wilt, so prevention is key. Make sure to rotate your crops and avoid planting tomatoes in the same spot year after year. You can also choose disease-resistant varieties, although German Johnson is not known for its resistance to fusarium wilt.
- Tomato hornworms: These large, green caterpillars can quickly defoliate a tomato plant if left unchecked. Look for them on the underside of leaves and remove them by hand, or use an organic pesticide like neem oil to control them.
- Early blight: This fungal disease can cause yellowing and wilting of the leaves, as well as dark spots on the fruit. To prevent early blight, make sure your plants are spaced out to allow for good air circulation, and avoid overhead watering (which can spread the spores of the fungus).
- Cracking: German Johnson tomatoes are known for their large size, which can make them prone to cracking if they absorb too much water. To prevent cracking, make sure to water your plants deeply but infrequently, and avoid getting water on the leaves or fruit. You can also try using a mulch to help regulate soil moisture levels.
By being aware of these common problems, you can take steps to prevent them from affecting your German Johnson tomato plants and enjoy a bountiful harvest of delicious, juicy fruit.
