How to Grow Tomatoes: A Comprehensive Guide

Growing tomatoes can be one of the most rewarding experiences for a gardener. Not only do tomatoes thrive in a variety of climates, but they also come in a wide array of flavors, colors, and sizes, making them a versatile addition to your garden. This guide will walk you through the process of growing tomatoes, address common problems and their solutions, and recommend five of the best tomato varieties to consider.

Getting Started with Tomato Growing

Choosing the Right Variety

Before you plant your tomatoes, it’s important to choose the right variety for your garden. Tomatoes come in determinate (bush) and indeterminate (vine) types. Determinate tomatoes grow to a certain height and stop, producing fruit all at once, making them ideal for canning. Indeterminate tomatoes continue to grow and produce fruit throughout the season, perfect for fresh eating.

Best 5 Tomato Varieties

  1. Brandywine: Known for its exceptional flavor, Brandywine tomatoes are large, beefsteak-type tomatoes with a rich, sweet taste. They are indeterminate and heirloom, meaning they are open-pollinated and come from seeds that have been handed down through generations.
  2. Roma: Roma tomatoes are a determinate variety that produces meaty, oblong fruits perfect for sauces and pastes. They have fewer seeds and a thick flesh, making them ideal for cooking.
  3. Cherry Tomatoes: Sweet and small, cherry tomatoes like ‘Sun Gold’ or ‘Sweet 100’ are indeterminate and produce clusters of bite-sized fruits. They are excellent for salads and snacking.
  4. San Marzano: Another great determinate variety, San Marzano tomatoes are renowned for their use in Italian cooking. They have a dense, meaty texture and fewer seeds, ideal for making sauces.
  5. Early Girl: As the name suggests, Early Girl tomatoes are among the first to ripen. They are indeterminate and produce medium-sized, round fruits that are perfect for slicing.

Preparing the Soil

Tomatoes thrive in well-draining, fertile soil. Here’s how to prepare your garden bed:

  1. Soil Testing: Test your soil to determine its pH level and nutrient content. Tomatoes prefer a pH between 6.2 and 6.8. Not sure how to test your soil? With a soil test kit! They are cheap and easy to use. Plus they will eliminate the guesswork.
  2. Amending Soil: Add compost or well-rotted manure to improve soil fertility and structure. If your soil is too acidic, add lime to adjust the pH.
  3. Mulching: Mulch around the plants to retain moisture, suppress weeds, and maintain soil temperature.

Planting Tomatoes

Starting from Seeds

  1. Sowing Seeds: Start seeds indoors 6-8 weeks before the last frost date. Sow seeds in seed-starting mix, covering them lightly with soil.
  2. Transplanting Seedlings: Once seedlings have two sets of true leaves, transplant them into larger containers. Harden them off by gradually exposing them to outdoor conditions for a week before planting them in the garden.

Transplanting Outdoors

  1. Choosing a Site: Select a sunny spot with at least 6-8 hours of direct sunlight daily.
  2. Planting Depth: Plant tomatoes deep, burying two-thirds of the stem. This encourages the development of a strong root system.
  3. Spacing: Space determinate varieties 18-24 inches apart and indeterminate varieties 24-36 inches apart.

Caring for Tomato Plants

Watering

Tomatoes need consistent moisture but avoid waterlogging. Water deeply at the base of the plants, aiming for 1-2 inches of water per week. Inconsistent watering can lead to problems like blossom end rot and fruit cracking.

Fertilizing

Use a balanced fertilizer or one specifically formulated for tomatoes. Fertilize at planting and then every 4-6 weeks throughout the growing season. Too much nitrogen can lead to lush foliage but fewer fruits, so balance is key.

Pruning

Prune indeterminate varieties to remove suckers (small shoots that develop in the crotch between the stem and a branch). This encourages larger fruit production and better air circulation. For determinate varieties, minimal pruning is required.

Supporting Your Tomato Plants

Tomato plants, especially indeterminate varieties, benefit from support to keep them upright and prevent disease. Here are some methods:

  1. Staking: Drive a stake into the ground near the base of the plant and tie the main stem to the stake as it grows.
  2. Caging: Use tomato cages to support the entire plant. This is especially useful for determinate varieties.
  3. Trellising: For indeterminate varieties, use a trellis system to allow the vines to climb and spread out.

Common Problems and Solutions

Growing tomatoes comes with its challenges. Here are some common problems and how to solve them:

1. Blossom End Rot

Symptoms: Dark, sunken spots on the bottom of the fruit.

Cause: Calcium deficiency due to inconsistent watering or low calcium levels in the soil.

Solution: Maintain consistent soil moisture and add calcium sources like crushed eggshells or agricultural lime to the soil. Mulching can also help retain soil moisture.

2. Early Blight

Symptoms: Dark, concentric spots on lower leaves, causing yellowing and leaf drop.

Cause: Fungal infection.

Solution: Remove affected leaves, improve air circulation, and apply fungicides if necessary. Rotate crops annually to prevent recurrence. Mulching can also prevent soil-borne spores from splashing onto leaves.

3. Late Blight

Symptoms: Dark spots on leaves, stems, and fruit, with a fuzzy white growth under humid conditions.

Cause: Fungal infection.

Solution: Remove and destroy affected plants, avoid overhead watering, and use resistant varieties. Apply copper-based fungicides as a preventive measure. Ensure good air circulation and keep foliage dry.

4. Tomato Hornworms

Symptoms: Large, green caterpillars with a horn-like tail, feeding on leaves and fruit.

Cause: Larvae of the hawk moth.

Solution: Handpick caterpillars and drop them into soapy water. Use biological controls like Bacillus thuringiensis (Bt) or introduce natural predators like ladybugs and lacewings. Regularly inspect plants for eggs and larvae.

5. Cracking

Symptoms: Radial or concentric cracks on the fruit, often after heavy rain.

Cause: Rapid changes in soil moisture levels.

Solution: Maintain consistent watering practices and mulch to retain soil moisture. Choose crack-resistant varieties. Harvest fruits as soon as they are ripe to prevent further cracking.

6. Aphids

Symptoms: Small, green or black insects clustered on new growth, sticky residue on leaves.

Cause: Insect infestation.

Solution: Spray plants with a strong jet of water to dislodge aphids. Use insecticidal soap or neem oil. Introduce beneficial insects like ladybugs and lacewings.

7. Fusarium Wilt

Symptoms: Yellowing and wilting of lower leaves, progressing upward.

Cause: Fungal infection.

Solution: Remove and destroy infected plants. Plant resistant varieties and practice crop rotation. Avoid planting tomatoes in the same spot for at least three years.

Harvesting Tomatoes

Tomatoes are ready to harvest when they are fully colored and slightly firm to the touch. For the best flavor, pick tomatoes in the morning when the temperatures are cooler. Use a sharp knife or scissors to cut the fruit from the vine to avoid damaging the plant.

For determinate varieties, harvest when the majority of the fruit is ripe. Indeterminate varieties can be harvested throughout the season as they continue to produce new fruit.

Storing and Using Tomatoes

  • Fresh Storage: Store tomatoes at room temperature, away from direct sunlight. Do not refrigerate unless they are fully ripe or if you need to extend their shelf life. Refrigeration can cause loss of flavor and texture.
  • Preserving: Tomatoes can be canned, frozen, or dried for long-term storage. Blanch and peel tomatoes before canning or freezing to preserve their texture and flavor. Make sauces, salsas, or tomato paste for versatile use.
