The Comprehensive Guide to Planting and Growing Tomatoes: From Seed to Sauce
Tomatoes are a popular and versatile crop, grown in many backyard gardens and enjoyed in a variety of dishes. Whether you're a novice gardener or an experienced green thumb, this comprehensive guide to planting and growing tomatoes will provide you with everything you need to know to successfully cultivate these flavorful fruits.
When starting your tomato garden, you have two options: planting seeds or purchasing transplants. Seeds are a more affordable option and allow you to choose from a wider variety of tomato cultivars. To start seeds, plant them indoors 6-8 weeks before the last expected frost date in your area. Use seed-starting trays or pots filled with a sterile seed-starting mix, and keep the soil consistently moist and warm (70-80°F) until the seeds germinate.
If you prefer to purchase transplants, choose healthy, sturdy plants with green leaves and no visible signs of disease or pests. Transplants offer a head start on the growing season, which can be especially helpful in areas with shorter growing seasons.

There are hundreds of tomato varieties available, each with its own unique flavor, color, and growing characteristics. When selecting tomato plants for your garden, consider factors such as:
Growth Habit: Tomatoes can be classified into two primary growth habits - determinate and indeterminate. Determinate, or bush-type tomatoes, grow to a set height and produce a finite amount of fruit over a short period of time, usually 1-2 months. These plants are compact and suitable for smaller gardens or container gardening. Indeterminate, or vine-type tomatoes, continue to grow and produce fruit throughout the growing season until the first frost. These plants require more space and support, such as staking or caging, but can provide a continuous supply of tomatoes for an extended period.
Disease Resistance: Tomato plants can be susceptible to various diseases, such as verticillium wilt, fusarium wilt, and nematodes. When selecting tomato varieties for your garden, look for those with built-in resistance to these common diseases. Disease-resistant plants typically have a series of letters (such as VFN or VFNT) following their name, indicating the specific diseases they are resistant to. Choosing disease-resistant varieties can help ensure a healthier, more productive garden with fewer issues.
Climate: Tomatoes thrive in warm temperatures and full sunlight, but certain varieties are better suited to specific climates. For example, some tomatoes are more heat-tolerant, making them a good choice for gardeners in hot, dry regions. On the other hand, cold-tolerant varieties can withstand cooler temperatures and shorter growing seasons. When selecting tomato plants for your garden, research which varieties are known to perform well in your region to increase the likelihood of a successful harvest.
Flavor and Usage: Tomato varieties differ not only in size, shape, and color but also in flavor and texture. When selecting the right tomatoes for your garden, consider your personal taste preferences as well as how you plan to use the tomatoes. For example, cherry tomatoes are great for snacking and salads, while meatier tomatoes, such as Roma or San Marzano, are perfect for making sauces and canning. Heirloom varieties often offer unique flavors and colors but may require more care and attention than hybrid varieties. By considering both your taste preferences and intended usage, you can select the perfect tomato varieties for your garden.
Tomato cages are a great way to support your tomato plants as they grow, keeping them upright and preventing them from sprawling across your garden. A sturdy and well-designed tomato cage can help increase your tomato yield and make harvesting easier by keeping the fruit off the ground.
Tomatoes require well-draining soil and full sun (at least 6-8 hours of direct sunlight per day) to thrive. When choosing a garden site, keep these factors in mind to ensure the best possible environment for your plants. Look for an area that has good air circulation and is free from heavy shade or competition from other large plants or trees.
Once you have selected the ideal garden site, focus on preparing the soil. Begin by incorporating organic matter, such as compost, well-rotted manure, or leaf mold, to improve soil fertility and structure. These amendments will enhance the soil's ability to retain moisture and nutrients while also promoting proper drainage. This is particularly important for tomatoes, which are susceptible to diseases caused by excess moisture and poor drainage.
In addition to amending the soil with organic matter, it's crucial to ensure the soil has the correct pH for growing tomatoes. Tomatoes prefer a slightly acidic soil with a pH between 6.0 and 6.8. To determine your soil's pH, conduct a soil test using a home testing kit or by sending a sample to a local extension office. Based on the results, you may need to add amendments, such as lime (to raise the pH) or sulfur (to lower the pH), to achieve the ideal pH range for tomato plants.
Preparing the garden site properly will create a strong foundation for your tomato plants, increasing their chances of producing a bountiful harvest. By selecting the right location and taking the time to amend and adjust the soil, you can set your tomatoes up for a successful growing season.

When the soil temperature reaches at least 60°F and nighttime temperatures consistently stay above 50°F, it's time to transplant your tomato seedlings or purchased transplants into the garden. Plant tomatoes at least 24-36 inches apart in rows spaced 3-4 feet apart. Bury the stems of the plants up to the first set of true leaves, as this encourages the development of a strong root system. This practice, known as "deep planting," promotes the growth of additional roots along the buried stem, which can help improve the plant's overall health and ability to take up nutrients and water.
To reduce the risk of disease, practice crop rotation by avoiding planting tomatoes in the same location where tomatoes, peppers, eggplants, or potatoes were grown in the previous two years. These plants are all part of the Solanaceae family and share many common diseases and pests. Rotating the planting location helps to minimize the buildup of harmful pathogens in the soil and keeps your plants healthier in the long run. If space is limited, consider using containers or raised beds to grow tomatoes in a different area of your garden.

Proper care is essential for healthy, productive tomato plants. Key aspects of tomato plant care include:
Watering: Consistent, deep watering is crucial for tomato plants. Aim to provide 1-2 inches of water per week, either through rainfall or supplemental irrigation. Water at the base of the plant, avoiding wetting the leaves, which can lead to disease. To maintain consistent soil moisture and reduce evaporation, consider using drip irrigation or soaker hoses.
Fertilizing: Tomatoes are heavy feeders, and a balanced fertilizer can help promote growth and fruit production. Apply a slow-release fertilizer at planting time, and then use a liquid fertilizer, such as compost tea or fish emulsion, every 2-3 weeks once the plants start to set fruit.
Staking or Caging: To keep your tomato plants off the ground and prevent disease, provide support using stakes, cages, or trellises. Indeterminate varieties require more robust support due to their continuous growth.
Pruning: Regular pruning can help improve air circulation, reduce disease, and increase fruit production. Remove any diseased, damaged, or yellowing leaves as needed. For indeterminate varieties, prune any suckers (the growths that appear between the main stem and the leaf axils) to encourage larger fruit and prevent overcrowding.
Pest and Disease Management: Inspect your tomato plants regularly for signs of pests, such as aphids, hornworms, or whiteflies, and use appropriate organic or chemical controls as needed. To reduce the risk of disease, practice crop rotation, avoid overhead watering, and remove any diseased plant material promptly.

Tomatoes are typically ready for harvest when they reach their full color and are slightly firm to the touch. To determine if a tomato is ripe, give it a gentle squeeze; it should have a slight give, but not be overly soft or mushy. To avoid damaging the plant, use scissors or a sharp knife to cut the fruit from the vine, leaving a small portion of the stem attached. This helps to prevent the fruit from rotting and keeps the remaining tomatoes on the plant healthy.
Store harvested tomatoes at room temperature and out of direct sunlight. Avoid refrigerating tomatoes, as this can negatively impact their flavor and texture. Cold temperatures can cause the cell membranes in the tomato to break down, resulting in a mealy texture and diminished taste. If you need to store tomatoes for an extended period, consider canning, drying, or freezing them to preserve their flavor and nutrients.
If frost is imminent and you still have unripe tomatoes on the vine, you can pick them and bring them indoors to ripen. Place them in a paper bag or cardboard box with a ripe banana or apple, which releases ethylene gas to help speed up the ripening process. This gas is a natural plant hormone that triggers the ripening and softening of fruits. Keep the bag or box in a cool, dark place, and check on the tomatoes every day to monitor their progress. Once they have reached the desired ripeness, remove them from the bag or box and enjoy them as you would fully vine-ripened tomatoes.
Canning Tip: It is not safe to can tomatoes that freeze on the vine. However, it is safe to can them if frozen in the freezer (with some exceptions). Checkout more about safely canning tomatoes here: https://enewsletters.k-state.edu/postrockdistrictfcs/2017/11/30/canning-previously-frozen-tomatoes/
