How long does tomato plant live? Tomato plants only survive for one growing season  6-8 months when grown outdoors, but they can live for two to five times as long when cultivated in optimum or regulated circumstances indoors. If you can get some healthy cuttings, you could perhaps keep it alive forever that way.

The common tomato, which has its origins in tropical South America, was not designed for rapid expansion in cooler regions.

Nonetheless, if you put in the time and energy, your homemade tomato plant will succeed. Let’s get a better understanding of the life cycle of this plant, the things that stunt its development, and the best ways to care for it.

The life cycle of the tomato plant

The tomato plant has a life cycle that consists of four stages: germination or seeds, growth, flowering, and fruiting.

  • Germination or seed: During germination last 6-8 weeks, the tomato seed absorbs water and begins to swell. This triggers the release of enzymes which break down the seed’s food reserves and the embryo inside the seed starts to grow.
  • Growth: The first true leaves of the tomato plant start to grow and the plant begins to take in nutrients and water. The tomato plant will continue to grow in height and spread its roots until it is ready to start flowering.
  • Flowering: When the tomato plant reaches maturity, it will begin to produce flowers. These flowers will eventually become the tomatoes we eat.
  • Fruiting: After the flowers are pollinated, they form small green fruits which will grow and ripen over time. The tomato plant will continue to produce fruits until the end of its life cycle.

Seed germination is considered to be the initiation of the first developmental phase in the lifecycle of higher plants and is followed by the postgerminative growth of the seedling

Some factors tomato plants to wither and die

There are several factors that can trigger death in tomato plants, including:

  • Unfavorable weather conditions: Tomato plants need adequate sunlight and water to thrive, and extreme temperatures, either too hot or too cold, can cause plants to die.
  • Diseases and pests: Tomato plants are particularly vulnerable to fungal diseases and insect pests, both of which can cause a plant to become diseased or die.
  • Poor soil quality: Tomato plants need nutrient-rich, well-draining soil to grow properly. Poor soil quality can lead to a lack of nutrition, stunting growth and eventually causing death.
  • Over-fertilizing: Too much fertilizer can cause tomato plants to become overburdened with nutrients, which can lead to the plant’s death.
  • Unbalanced watering: Tomato plants need water to survive, but too much water can lead to root rot, which can cause the plant to die.

The life span of tomato plants in a greenhouse

Greenhouse-grown tomato plants can live for 6-8 months or 1-3 years since they have year-round access to regulated temperatures and humidity, as well as protection from direct sunshine and pests.

The warm, regulated temperature also promotes improved nutrient absorption from the soil and fertilizer.

The life span of tomato plants in indoor

Tomato plants are hardy enough to grow successfully inside for up to two full growing seasons if given the right conditions. (2 years).

The life span of tomato plants in hydroponic

Tomatoes that are cultivated hydroponically are grown in nutrient-rich water rather than soil, and they can be stored for anywhere from eight to eleven months.
However, the lifespan of hydroponically grown tomato plants can range anywhere from six months to two years, and it all depends on the quality of the water utilized in the growing process.

Cherry tomato plant lifespan

The cherry tomato is an heirloom variety that is known for its large, red tomatoes that are typically eaten fresh. Cherry tomatoes typically have a yield of about 4 to 6 per plant and will reach maturity around 80 days after planting.

Thus, you already know how long does a tomato plant last, but what are some of the best tips to keep them going strong? Now, let’s explore the next part.

The following tips will help you keep your tomato plants healthy and thriving:

 Provide optimal growing conditions

Tomato seeds germinate in about a week to two weeks at 65 to 85 degrees Fahrenheit with twice-daily watering, and more light (try these grow lights) can keep the plants from developing flimsy stems while the leaves are unfolding.

After being transplanted, tomato plants do best in a pH range of 6.2–6.8 soil and 6–8 hours of direct sunlight every day.

Aspects of the weather

Tomatoes are at their most delicious when cultivated in regions with warm days and cool nights. They thrive in the milder climates of the southern and western United States but can be cultivated elsewhere.

Staking and pruning

Remove any sick or dead leaves, cut off any small suckers before they become large, and stake your tomato plant to prevent it from toppling over. Avoid damaging the branches by securing them with soft twine, old rags, or nylons.

Moreover, larger plants can be supported by tying them to a post or cage with twine and pruning to maintain a desired shape and size.

Tomatoes benefit from companion planting

In addition to companion planting with other plants that help to remove pests and provide nutrients for the tomato plant. A few examples follow:

  • Cilantro: The root system of cilantro aerates the soil, and parsley’s fragrant components deter pests.
  • Basil: Basil is a member of the mint family and its oils help deter insects, while its strong fragrance deters fungal diseases.
  • Lettuce: Lettuce leaves act as natural mulch, trapping moisture and helping to keep the soil moist. Placing lettuce around your tomato plants will also help to control weeds.
  • Thyme: Thyme is a mint family member and its leaves, as well as the roots, help to control harmful fungi.

Fertilize regularly

It is essential to fertilize your plants on a consistent basis in order to ensure a stable yield of fruit.  Since tomatoes are big feeders, feeding plants high-quality fertilizer regularly will help them flourish.

Remove the fruit before it starts to ripen

As soon as the tomatoes start to turn red and the seeds begin to grow, it is time to harvest them. Ripe fruit will be soft to the touch, with a slightly acidic flavor, and will have a bitter aftertaste.

Treat pest and disease problems right away

If you experience any problems with pests or diseases, take action right away by using organic methods. Including spraying insecticides or fungicides, and treating the plants with a soil drench.

Tomato cuttings root

Detecting problematic symptoms on the fruit and foliage early enough. They can salvage otherwise healthy harvests. Mold patches and bug infestations can both be treated on-site using a garden fungicide or an organic pesticide.

Long-term problems can be avoided by watering at the soil level rather than the foliage level. Using high-quality fertilizer to boost disease resistance, and rotating crops every 2-3 years.

Bring tomato plants inside prior to the first frost

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

Find out when the ground will freeze in your location, and then dig out the plant and replant it in a container.

Put it in a warm, humid environment (like a greenhouse or a garage) with a temperature range of 65°F to 85°F and some grow lights.

What is the minimum temperature a tomato plant can withstand?

Tomato plants, as reported by the United States Department of Agricultural Research, can withstand temperatures as low as 33 degrees Fahrenheit, but they will die in temps lower than 32 degrees.

Tomato plants have trouble sprouting at temperatures below 50 degrees Fahrenheit, and even at higher temperatures, their growth is stunted.

Fruit from cold-hardy cultivars will develop at temperatures as low as 50-60 degrees Fahrenheit, although the optimal growing temperature is 70 degrees and higher.

Methods for increasing the length of the harvest season

Increasing the length of the harvest season can be beneficial for farmers. This allows them to benefit from the production of a larger number of crops over the course of the season. There are a number of methods that can be used to extend the harvest season.

First, crop rotation can be used to increase the length of the harvest season. Each year, the farmer plants different crops in different regions of the farm to ensure a consistent supply of produce.

In addition, planting different varieties of the same crop can also help to extend the harvest season.

Second, tomatoes need to be protected from the cold in order to extend the harvest time. The highest results for increased yields are typically obtained in clayey and loamy soils.

Third, Row covers, greenhouses, and hoop buildings can extend the harvest season. These structures can shelter crops from cold and poor light, allowing them to mature and be harvested longer.

Finally, the use of climate-controlled storage facilities can also help to extend the harvest season. By storing harvested crops in a cool, dry place, farmers can ensure that they remain fresh and edible for longer periods of time.

Can tomatoes grow throughout the year?


In mildly cool locations, tomatoes can be grown outside year-round, but bringing them inside toward the end of the growing season will extend the time until harvest. Then you’ll have access to fresh, home-grown tomatoes all through the year.

FAQs: How long does a tomato plant live?

How many tomatoes can one plant make?

The Old Farmer’s Almanac explains that determinate tomato plants are “programmed” to grow, flower, and bear fruit just once throughout a growing season. After these small plants have produced their fruits, they stop making fruits and eventually die.

When do I stop growing tomatoes?

When should you quit eating tomatoes? Depending on where you garden and what time of year it is, you may need to “stop off” the tomato plants in August or September. This implies pinching off the tips of growth at the top of the plant to stop it from growing any higher.

How do you know when a tomato plant has made all the tomatoes it can?

Here are a few clues that your tomato plants are probably done for the season and can be taken down:

  • They’re no longer making fruit.
  • They have lost their shape and look dry.
  • They aren’t making much new growth. You may pull them up by the roots. You can even chop them off at the bottom and let the roots rot.

How many times can tomatoes be grown in the same spot?

First, you should never plant tomatoes (or potatoes) in the same soil two years in a row. Root-knot nematodes are attracted to them, but they don’t hurt the plants in the first year. In the second year, though, as the number of nematodes grows, the plants get sick and often die.


In conclusion, tomato plants live for around 6-8 months. companion planting with other plants can help to control pests and diseases while fertilizing on a regular basis will result in a stable yield of fruit.
