How long do tomato plants live?

In this brief article, we are going to answer the question, “How long do tomato plants live?”

How long do tomato plants live?

A tomato plant normally survives for six to eight months. However, with proper care and attention to detail, an indoor tomato plant may last between two and five years. 

This depends on the type of environment in which it is maintained. It’s possible to keep propagating healthy cuttings indefinitely.

The life lifetime of tomato plants is governed by the variety, location, and care they receive during each step of their growth cycle, which can range from a few months to many years.

How long do tomato plants live in a greenhouse?

Due to their year-round access to controlled temperatures and humidity, greenhouse grown tomato plants could expect to thrive for up to three years.

Nutrient uptake from the soil plus fertilizer is also enhanced by an artificially warm and humid atmosphere.

How long do hydroponic tomatoes live?

According to Upstart University in partnership with innovators of vertical farming technology, hydroponic tomatoes are cultivated in nutrient rich water instead of soil and may endure between 8-11 months.

Hydroponic tomato plants can survive anywhere from six months to two years, depending on the quality of the water utilized.

What is the lifecycle of a tomato plant?

Phase 1: The Seedling

Seeds should be started inside 6 to 8 weeks just before the last frost date, since warm soil encourages germination. Those plants that are 6 to 10 inches in height and have purple veining in their leaves are able to be transferred into the ground once the fear of frost has gone.

Phase 2: Leaf Growth

When a plant reaches a height of 12-18 inches, it begins to produce new stems and flower buds, doubling in size every two weeks.

Phase 3: Flowering 

Trellises or stakes are needed to support the first golden blossoms in late spring or early summer. This can lead to inadequate pollination and the loss of blooms.

Phase 4: Growth of the Fruit

Pea-like proliferation of emerging new tomatoes replaces the faded blossoms. At 70-80 days of maturation, the fruit is still green but will eventually become a spectrum of colors according to the type.

How can you extend the life of tomato plants?

Create Optimal Conditions for Plant Growth

Supplemental light (such these grow lights) helps avoid lanky stems during leaf growth in tomato seeds, which germinate in just 1-2 weeks at temperatures between 65°F to 85°F.

After that, transferred tomato plants will thrive in soil with a pH of 6.2-6.8 and 6-8 hours of direct sunshine every day.

Additionally, they should be watered often and treated with a high-potassium fertilizer as soon as they begin to blossom.

Prevent Ripening by Disposing of Fruit Early

To pick your tomatoes, wait until they’ve become a pale pink instead of green.

“The breaker stage is when the tomato stops drawing resources from the plant and may be plucked from the vine without losing taste, quality, or nutrition at the 12 green or pink stage.

Routinely Apply Fertilizer

A good NPK (nitrogen-phosphorus-potassium) ratio is 18-18-21, such as Miracle-Gro Plant Food for tomato plants.

A watering can solution of 12 tablespoon fertilizer and 112 gallons of water should be applied to the soil of the outdoor plant.

Fertilize as soon as you plant, and then increase the frequency about once every 2 weeks while the plant is in bloom and producing fruit.

Stump Tomato Roots

Make sure your tomato plant’s life span is extended by making healthy cuttings and “propagating” them.

It’s common for tomato plants to put outside shoots in May to June after producing a good cluster of fruit, but you may keep them then root them in the water by following this easy approach.

Before the first frost, bring tomato plants indoors.

If you want to keep your plant for the next growing season, you’ll need to protect it from the first sign of cold weather.

Make sure you know when the very first frost date is in your region so you can remove the plant from the ground and put it in an appropriate container.

Ideally, it should be in the greenhouse or garage with grow lights and a microclimate ranging from 65 to 85 degrees Fahrenheit.

What temperature can a Tomato Plant withstand?

Tomato plants can withstand temperatures as low as 33°F, but will die if temps fall below 32°F, according to the United States Department of Agricultural Research.

Tomato plants cannot germinate or thrive at temperatures below 50 degrees Fahrenheit, which is a concern for both seedlings and mature plants.

Cold-hardy types may tolerate temperatures as low as 50-60°F and still produce fruit, but the plants will not flourish unless temperatures are raised to at least 70°F.
