How Long Do Plants Live?

We have often heard about that banyan tree that has lived through the ages. On the other hand, we have seen banana trees that die after growing bananas for a season. In comparison, both these trees seem to have an age till which they can live. It makes us wonder, how long does a plant live?

How long do plants live?

Plants, in general, have no specific lifespan. They live until the conditions for their growth are near perfect. However, we know that the conditions of growth change with time. Thus, this causes the plant to die with time. However, some plants, such as bananas, are naturally meant to grow for one growing season. They are called annuals, and they tend to die after flowering and producing food for one season.

So, we can see that the plants have no lifespan. However, their imminent death is caused by a change in the factors. While it is true that we cannot control all the factors, we can still try to balance some of the factors which can help ensure that the plants live longer.

Factors on which plant survival depend

So, let us explore the factors on which the survival of the plant depends-

  • Water
  • Sunlight
  • Pests


Each plant has a specific amount of water that it needs to grow well. Failure to provide an adequate amount of water to the plant may cause severe problems. A lack of water may dehydrate the plant and cause it to die. On the other hand, excess water may cause it to turn soggy and make it prone to rotting. So, it is very important to know the amount of water your plant requires.


The best way is to understand the water requirements of the plant. Generally, watering it when the soil turns dry can help you keep the plant adequately hydrated. However, stagnant water left behind in the pot can be fatal to the health of the plant. So, it is very important to ensure that the pot has proper drainage holes before potting the plant.


Sunlight is essential to the plant to carry out the function of photosynthesis. Without adequate sunlight, the plant cannot produce its food, and it starts to starve. It can cause the plant to etiolate and become weak. Similarly, excess sunlight can cause sunburns and lead to permanent damage to the plant.


Always allow your plant to grow in a location where it has access to at least six hours of indirect bright light throughout the day. If your plant is kept indoors, place it near a south-facing window or use artificial lighting to provide the plant with adequate light.


Plants can be prone to common pests such as aphids, mites, and mealybugs. These pests tend to suck on the sap of the plant and cause it to weaken. If left untreated, it can lead to the death of the plant.


If a pest infestation is spotted, immediately isolate the plant to contain the spread. Spray it with an effective fungicide till the pests have been eradicated to reduce chances of reinfection.

Thus, these are the steps to help your plant live longer.
