Growing Determinate Tomato Plants: How to Encourage Early Fruit

Many gardeners are eager to see a bountiful harvest from their tomato plants. However, it can be frustrating when your Moscow tomato plants are about 2 feet high but show no signs of fruit. Given that it is a determinate tomato variety expected to reach maturity in 60 days, it's natural to wonder when you might start seeing those coveted tomatoes. This article will help you understand whether your plants are on track for a successful harvest and what you can do to encourage early fruiting.

Understanding Determinate Tomatoes

A determinate tomato plant, also known as a bush type, grows to a predetermined height and then stops. These plants typically produce all of their fruit within a 2- to 3-week period (about 60 days from transplanting). Moscow is indeed a determinate variety, meaning it should theoretically produce fruit within 60 days when conditions are ideal.

Factors Affecting Early Fruit Set

There are several factors that can influence whether your Moscow tomato plants are on track for early fruit set. One of the primary concerns is the absence of flowers turning into fruit, despite the plant's growth. While some tomatoes can self-pollinate without wind, certain conditions, such as insufficient wind or pollination issues, might impede fruit development.

Wind and Pollination

Tomatoes, especially determinate varieties, rely on wind to help move pollen from the male parts of the flower to the female parts. If there is a lack of wind, the process can be slow or inefficient, resulting in a delay in fruit set. Similarly, bees and other insects play a crucial role in pollination. If the weather conditions are not favorable or there is a lack of pollinators, it can result in poor flowering and fruiting.

Encouraging Early Fruit Set

To help your Moscow tomato plants mature their fruit sooner, consider the following steps:

Manual Pollination

One effective method is to lightly use an electric toothbrush to vibrantly shake and brush the flowers. This can help to physically transfer pollen from the stamens to the pistils. Alternatively, gently shaking the plants several times a day can simulate the wind and promote natural pollination. A fan placed near the plants can also aid in this process.

Nutrient Management

To support robust plant growth and fruit production, ensure the soil is rich in essential nutrients. Calcium is crucial for nutrient absorption, while magnesium is vital for stem strength and overall plant vigor. Applying a balanced fertilizer or compost can help supply these nutrients, ensuring your tomato plants have the energy needed to produce fruit.

Patience and Monitoring

Given that your Moscow tomato plant is about 2 feet high, it is within the normal growth range. Patience is key as the plant continues to grow and develop. Keep an eye on the plants, and monitor the flowers for any signs of fruit development. With ideal conditions and proper care, you should start seeing some fruit between 60 to 70 days after transplanting.

Conclusion

While your Moscow tomato plants are still at an early stage, there is still hope for an early harvest. By ensuring adequate wind, encouraging pollination, and providing essential nutrients, you can help your plants reach their full potential. With patience and effort, you will soon enjoy the juicy, flavorful tomatoes that determinate varieties like Moscow are known for. Happy growing!
