Growing Guide: Tomatoes

Welcome to the Gardenbox Growing Guide for Tomatoes! Tomatoes are one of the most popular and rewarding vegetables to grow, offering a delicious bounty that can be enjoyed fresh or in various dishes. Follow our step-by-step guide to grow healthy, productive tomato plants.

Choosing the Right Variety

Determinate vs. Indeterminate: Determinate tomatoes grow to a fixed size and produce all their fruit at once, making them ideal for container gardening. Indeterminate tomatoes continue to grow and produce fruit throughout the season, requiring more space and support.
Heirloom vs. Hybrid: Heirloom tomatoes are open-pollinated and known for their rich flavors, unique colors and exotic shapes, cherry and grape tomatoes are tomatoes that can be eaten in one bite, and typically grow in large bunches on the plant, while hybrid tomatoes are bred for disease resistance and uniformity. However, keep in mind that there are heirloom cherry tomatoes, hybrid tomatoes that have an "heirloom" shape, and every exception to the rule you can imagine.

Starting Seeds Indoors: Start tomato seeds indoors 6-8 weeks before the last expected frost date. Use seed trays or small pots filled with seed-starting mix. Keep the soil moist and provide plenty of light.
Transplanting: Transplant seedlings outdoors after the danger of frost has passed and the soil has warmed. Choose a sunny location with well-drained soil. Harden off seedlings by gradually exposing them to outdoor conditions over a week.
Spacing: Space determinate varieties 18-24 inches apart and indeterminate varieties 24-36 inches apart. Ensure rows are about 3-4 feet apart to allow for proper air circulation.

Soil and Fertilization

Soil Preparation: Tomatoes thrive in rich, well-drained soil with a pH of 6.0-6.8. Amend soil with compost or aged manure to improve fertility and structure.
Fertilizing: Use a balanced fertilizer when planting, and side-dress with a high-phosphorus fertilizer when flowers appear. Avoid excessive nitrogen, which promotes foliage growth over fruit production.

Watering and Mulching

Watering: Keep the soil consistently moist but not waterlogged. Water deeply at the base of the plant, avoiding overhead watering to reduce the risk of disease. Mulch around the base to retain moisture and suppress weeds.
Mulching: Apply a layer of organic mulch, such as straw or shredded leaves, to help maintain soil moisture and temperature.

Staking and Pruning

Staking: Support indeterminate varieties with stakes, cages, or trellises to keep plants upright and improve air circulation. Tie the plants loosely to the support as they grow.
Pruning: Prune suckers (small shoots that develop in the leaf axils) on indeterminate varieties to focus the plant’s energy on fruit production. Remove any yellow or diseased leaves to prevent the spread of disease.

Pest and Disease Management

Common Pests: Watch for aphids, tomato hornworms, and whiteflies. Use organic insecticidal soap or neem oil to control infestations. Encourage beneficial insects like ladybugs.
Diseases: Prevent diseases such as blight and fusarium wilt by rotating crops, spacing plants properly, and avoiding overhead watering. Remove and destroy infected plants immediately.

Harvesting

Timing: Harvest tomatoes when they are fully colored and slightly firm to the touch. Gently twist or cut the fruit from the vine.
Storing: Store ripe tomatoes at room temperature and avoid refrigeration to preserve their flavor. We have to say that again because it is super important. Never put uncut tomatoes in the refrigerator. Use soft overripe tomatoes for sauces and canning.

Tips for Success

Companion Planting: Plant tomatoes with basil, marigolds, or carrots to enhance growth and repel pests.
Consistent Care: Regularly check for pests, diseases, and nutrient deficiencies. Provide consistent care to ensure a bountiful harvest.
