List of 9 Tomato Growing Tips That Really Work:


1. Strategic Fertilization

To ensure healthy growth and abundant harvests, tomatoes need careful fertilization management. Initially, they require a significant amount of nitrogen to develop strong leaves crucial for photosynthesis and overall vitality. As they transition to flowering and fruiting, it’s essential to switch to a fertilizer with lower nitrogen and higher phosphorus and potassium content.

This change promotes better fruit development and prevents excessive leaf growth. Espoma Organic’s Tomato Tone, with an N-P-K ratio of 3-4-6, is ideal for this phase, supporting robust fruit production while keeping the foliage healthy. This strategic fertilization approach helps tomatoes grow vigorously and produce a plentiful, delicious crop.

2. Seed Fermentation

For gardeners looking to extend the viability and health of their tomato seeds, fermentation offers a superior alternative to traditional drying methods. Begin by extracting seeds and pulp into a jar using the juice from a ripe tomato, which aids the fermentation process.

Allow the seeds to ferment for a few days; this breaks down the gelatinous coating that surrounds them, removing disease agents and enhancing their longevity. Once fermentation is complete, rinse the seeds thoroughly and spread them out to dry. This method not only ensures seeds are disease-free but also improves their storage potential, making them easier to plant when needed.

3. Ethylene-Induced Ripening

To accelerate the ripening of tomatoes that are still green due to early frosts or pests, utilize ethylene gas naturally produced by fruits like apples and bananas.

Simply place the unripe tomatoes in close proximity to these fruits in a box, positioning the blossom end upwards to prevent them from spoiling too quickly. It’s essential to check on them daily, as this method can rapidly advance ripening, and you’ll want to avoid the tomatoes becoming overly ripe.

4. Diverse Planting Times

To manage your tomato harvest effectively, consider planting varieties with different maturity times or staggering your planting dates.

For example, Sun Gold cherries mature in 57 days, Pink-a-licious beefsteaks take 70 days, and Tasmanian chocolates require 85 days. This strategy prevents all your tomatoes from ripening at once, ensuring a continuous supply throughout the season and avoiding excess all at once.

5. Deep Planting Technique

To strengthen tomato plants, especially tall, leggy seedlings, use the deep planting technique by burying them up to two-thirds of their stem height. This encourages the buried stem to sprout additional roots, enhancing stability and nutrient uptake.

In cooler climates, ensure the soil temperature is above 55 degrees Fahrenheit with a soil thermometer before planting. If temperatures are too low, consider planting seedlings horizontally in a shallow trench as an alternative to promote robust root growth.

6. Top Pruning

Top pruning, also known as pinching off, is a crucial technique for tomato plants, particularly as the growing season draws to a close.

This technique is especially beneficial when you need to accelerate the ripening process, ensuring tomatoes mature faster and are ready for harvest before any risk of frost or end-of-season decline.

7. Sunlight Optimization

To maximize the growth and fruit production of tomato plants, it’s essential to optimize sunlight exposure. Large fruiting varieties, such as beefsteaks, need at least 10-12 hours of direct sunlight daily due to their size and energy requirements.

In contrast, smaller varieties like cherry tomatoes can thrive with slightly less sunlight. For gardeners in areas with limited sunlight, prioritize the sunniest spots for larger varieties and allocate the less intense sun areas to smaller ones. This strategic placement ensures that all your tomato plants have the best conditions possible for healthy growth and abundant yields.

8. Cloning Your Favorites

Cloning is an effective way to quickly propagate your favorite tomato varieties, especially if you’re pressed for time. To clone a tomato plant, select a healthy sucker, which is a small shoot that grows from the stem.

Carefully remove it and place it in water or a moist seed-starting mix to encourage rooting. This method bypasses the longer germination period of seeds, allowing you to expand your tomato garden more rapidly and efficiently, potentially saving weeks of growth time.

9. Efficient Space Utilization

For gardeners dealing with limited space, effective pruning is key to maximizing yield. By trimming tomato plants to maintain just one or two main stems, you can plant them closer together.

This not only saves space but also accelerates fruiting, as the plants aren’t expending energy on multiple stems. This approach allows you to cultivate a diverse range of tomato varieties within a small area, optimizing your garden’s productivity and variety.

Bonus Hack: Dry Farming Tomatoes

Dry farming tomatoes is an innovative technique adapted from viticulture, where tomatoes are grown without supplementary irrigation. This method is particularly effective in areas with clay-rich soils and moderate climates that benefit from seasonal rainfall.

By relying solely on natural precipitation, the plants experience a level of stress that can significantly enhance the flavor and texture of the tomatoes, producing a more intense and satisfying taste. This water-conservation method not only saves resources but may also result in superior quality produce.


Troubleshooting Tips for Tomato Gardening Hacks

While the hacks outlined in this article can greatly enhance your tomato gardening experience, sometimes you might encounter a few hiccups along the way. To help you navigate these potential challenges, here are some troubleshooting tips for common issues:

  1. Fermentation Not Starting: If you notice that your seeds are not fermenting, check the temperature of the room. Fermentation requires a warm environment (around 70°F). Also, ensure that there is enough natural juice in the seeds to kickstart the process.
  2. Challenges with Dry Farming: If your dry-farmed tomatoes seem stressed or your yield is low, consider adjusting the timing of your planting to ensure the soil has adequate moisture from seasonal rains. Additionally, adding a layer of mulch can help retain soil moisture without watering.
  3. Over-pruning: If you find you’ve pruned too much and your plants are struggling, reduce the frequency of pruning and allow the plants to recover. Make sure they have enough leaves to conduct photosynthesis and support growth.
  4. Ethylene Ripening Issues: If tomatoes ripened with ethylene gas from fruits are tasting off or ripening unevenly, ensure they are not too crowded and have sufficient air circulation around each fruit. Also, monitor daily to adjust the proximity to the ethylene-producing fruits as needed.

Advanced Varietal Advice for Tomato Gardening Hacks

Choosing the right tomato varieties is crucial to maximizing the benefits of each gardening hack. Here’s a guide to help you select the best tomato varieties based on your gardening goals and conditions:

  1. For Ethylene-Induced Ripening: Opt for varieties that ripen uniformly and are known for their robust flavor when ripened off the vine, such as ‘Celebrity‘ and ‘Early Girl‘. These varieties respond well to ethylene and are ideal for climates prone to early frosts.
  2. For Dry Farming: Choose varieties that are drought-resistant and have deep root systems capable of extracting moisture from clay soils. ‘San Marzano’ and ‘Brandywine’ are excellent choices for dry farming, known for their ability to develop intense flavors under water stress.
  3. For Diverse Planting Times: To stagger your harvest, select a mix of early, mid-season, and late varieties. ‘Sungold’ (early), ‘Beefmaster’ (mid-season), and ‘Amish Paste’ (late) provide a continuous supply of tomatoes throughout the growing season.
  4. For Deep Planting: Varieties like ‘Roma’ and ‘Better Boy’ are particularly suited for deep planting as they have vigorous root systems that benefit from the deeper soil contact, leading to stronger, more resilient plants.
  5. For Top Pruning: Choose indeterminate varieties such as ‘Big Beef’ or ‘Cherokee Purple’ that continue to grow and produce fruit throughout the season. These varieties benefit significantly from top pruning as it helps concentrate the plant’s energy on fruit maturation.
  6. For Cloning: Look for vigorous, disease-resistant varieties that can easily produce suckers for cloning. ‘Sweet Million’ and ‘Cherry Bomb’ are great choices because of their robust growth and ability to quickly root from cuttings.
