Growing Healthy Tomato Plants

When selecting tomato plants for your garden, understanding the difference between determinate and indeterminate varieties is key to a successful harvest.

Determinate tomatoes are often referred to as “bush” tomatoes. They grow to a fixed height, typically 3-4 feet, and produce all their fruit within a short period. These plants are ideal for container gardening or compact spaces. Since they tend to grow in a controlled shape, a tomato cage is a great option for support. For best results, feed determinate plants with a balanced tomato fertilizer every 2-3 weeks during the growing season.

Indeterminate tomatoes, sometimes called “vining” tomatoes, continue to grow and produce fruit throughout the season until frost. They require sturdy support such as a tomato cage or stakes to keep their long vines upright. Regular pruning of excess foliage can help direct energy toward fruit production. Fertilize indeterminate varieties every 2-3 weeks with a quality tomato fertilizer to ensure steady growth and fruiting.

For both types, calcium is essential to prevent blossom end rot, a common issue where fruits develop dark, sunken spots. Adding calcium nitrate to the soil or as a foliar spray can help maintain healthy calcium levels. Additionally, epsom salt can be added to boost magnesium, promoting lush green leaves and improving overall plant health. Apply epsom salt at a rate of 1 tablespoon per gallon of water every 4-6 weeks for best results.

To extend your growing season and protect young plants, consider using a mini 3-tiered greenhouse for early planting and added warmth. Paired with strong tomato cages and the right fertilizer, your tomato plants will be well-supported and ready to thrive throughout the season.
