Checking If Your Bonsai is Dying

If you are an amateur Bonsai owner, simple mistakes like over-fertilizing or under-watering may happen. Doing so can leave your plant looking unhealthy. But do not fret as Bonsai trees are hard to manage even for an experienced gardener.

If you notice something amiss about your Bonsai tree, you should first figure out what is wrong with your plant. Bonsai trees will show signs when it is unhealthy. Some common signs that you should look out for are:


If there is discoloration on the leaves, it can be natural and due to seasonal changes. But if the color changes outside of normal, it might be due to a lack of sunlight, water, or malnutrition.

Overwatering can result in yellow or wilted leaves. Another reason can be receiving too much sunlight. Being exposed to too much sunlight can cause leaf burn for Bonsai plants

Patterns on leaves and barks

Sometimes you can see odd patterns or red spots on the leaves of barks. It can be a sign of either a disease or from bugs and pests. Before taking any action, it’s important to identify what the problem is first.

Red spots can also be a sign of spider mites, a very dangerous enemy of your dear plant. These insects can devour your Bonsai tree fast . So, it is best to take action as soon as you spot any bug.

Shrunk branches and leaves falling off

This is a sign of the tree weakening and shutting down. This can happen if the tree doesn’t get enough water and nutrition.

In this state, the tree doesn’t have enough energy to maintain itself and its leaves fall off. But sometimes shrunk branches might show due to being infected by diseases.

Brittleness of branches and leaves

Depending on the season and the species of your Bonsai, this sign can be due to natural causes. But if it happens as an unusual occurrence, it can be a sign of not being managed properly.

If the Bonsai is not receiving enough water or sunlight , brittles are a common sign. But it can also be due to using the wrong amount of fertilizer.

Abnormalities in the roots

It is best to examine the plant’s roots every year to keep your Bonsai tree healthy . If you find the plant’s roots discolored, brittle, or broken, this can mean the tree cannot take water and nutrients from the soil properly. 

You can also smell the roots to find if it smells weird. The presence of an unusual smell can indicate waterlogged soil. Crushed and compacted root can mean that they have outgrown their pot and needs to be transferred to a larger container. 

Revive your Dying Bonsai Tree

Unlike other average plants, Bonsai trees are unique as they can’t survive on their own. If your bonsai looks to be struggling, you might be wondering “can you bring back a dead bonsai tree?”. Good news for you, if you manage to provide just care, it will make a full recovery to a healthier state. So don’t give up and follow the following instructions:

  • Step 5: Prepare a new pot for you to place your Bonsai tree . It must be a clean pot in a size appropriate for the Bonsai tree. It’s best to get one slightly larger than the previous one to help the roots grow.

Common Mistakes You Should Avoid

There are some common beginner mistakes most new bonsai owners agonize over. Treating these mistakes might help your Bonsai thrive in a healthy state. The mistakes you should be aware of are:

Overwatering or under watering

Most bonsai problems are due to watering. It’s important to water your Bonsai tree the right amount. Only water the plant until the soil is completely wet. If there is water coming out of drainage holes, it means the soil is wet and you can stop watering it.

Placing an outdoor tree indoors

It’s crucial to know about your bonsai tree’s nature . An outside bonsai tree can’t survive indoors and the indoor ones can’t suit the inside environment. So before placing your Bonsai tree, figure out its nature.

Insufficient light

Even inside bonsai trees require a lot of light to survive. Choose a place where your tree can get enough natural light. If your home has a south-facing window, that might be just the place.

Wrong size container

A grown Bonsai tree will naturally need a bigger container. For the root systems to grow and stretch properly and take nutrition and water from the soil, the container needs to be the right size. So be mindful of when your Bonsai might need to be upgraded to a bigger pot.
