Growing and Taking Care of Bonsai Trees

The name ‘Bonsai’ literally translates to ‘tree in a pot.’ This is a simplistic way of summarising the small tree’s cultivation, but it hits the nail on the head, so to speak. Of course, bonsai is a much wider topic than the basic translation above, and therefore takes a bit more explanation. The Chinese art of growing and nurturing small trees that resemble life-size trees in nature is known as bonsai. It’s all about scale and proportion in bonsai.

Bonsai trees, which originated in China, require a great deal of care and attention, relying on their owners for trimming and maintaining, but some sellers have recently observed a nearly 700% increase in the number of people interested in purchasing one. The relaxing and mental health advantages of tending to such a needy yet attractive plant are said to be the reason for its popularity.

You may have started cultivating a bonsai tree from seed or purchased one that was already growing. In any case, knowing how long it takes to grow a bonsai tree is useful.

Method of Planting

Bonsai trees are genetically identical to their full-size counterparts, contrary to common perception. Their size, of course, distinguishes them from ‘regular’ sized trees. As a result, bonsai trees will take about the same amount of time to grow as full-grown trees. Faster growing species may take between 10-15 years to reach full size, whilst slower growing species may take 20-30 years to reach full size; this would also apply to bonsai trees. A Chinese elm, for example, could take up to 15 years to grow.

Bonsais can grow either from seeds or there are other alternatives as well. If you want to try growing them from seeds, you will have to train them to grow in a proper manner otherwise they will grow just like a regular plant. Growing your bonsai tree in ideal conditions will not only ensure that it is healthy but may also shorten the time it takes to reach full size by years. Optimal growing circumstances can ensure that your bonsai thrives and grows at a faster rate, therefore paying great attention to this is crucial.

Soil preparation

Compost should be mixed with perlite. 3 parts compost to 1 part perlite is a good ratio. This seems to work well for me. This mix holds water but also drains well, which is important because roots need to breathe and can rot if they are always submerged. 


The first step is to choose a location for your bonsai tree. If you choose an indoor species, don’t expect your bonsai to withstand low lighting all of the time. Place your bonsai in front of a south-facing window where it will receive lots of light throughout the day. A bright and sunny location is ideal for outdoor bonsais. Depending on the species you choose, you may need to shelter your bonsai tree during the winter to avoid freezing or extremely low temperatures. Otherwise, bonsais usually thrive when planted outside.

How to plant?

  • Take a seed tray, such as the black plastic ones seen in garden centres.
  • Fill the tray with compost (typically mixed with perlite for drainage and airflow).
  • Allow the excess water to drain away after watering to ensure that all of the compost is moist.
  • If the seeds are small, scatter them on the soil’s surface, or push larger seeds (acorns, for example) into the compost.
  • Add a fine coating of compost on the surface.
  • Cover the seed tray with plastic wrap. This can be done using clear plastic caps. On the internet, look for seed propagators.
  • Then hold your breath! It’s important to keep the soil hydrated. Watering cans may guzzle out too much water too rapidly, moving the seeds around in the tray, so a mist sprayer is ideal.

It takes a long time to grow bonsai trees from seed. It will take years to create something that resembles a bonsai, and a decade or more to create something that is absolutely impressive. There’s nothing wrong with this, but keep in mind how long it will take.



As with all plants, getting the appropriate light intensity is critical for bonsai tree growth. Sunlight is, of course, one of the most important aspects that can enhance or hinder plant growth, and it is necessary for a bonsai tree’s existence and health.


Water is another necessity, in addition to sunlight! Keeping your tree properly watered can make a huge difference in its growth. Under- and over-watering are fairly prevalent among beginner bonsai enthusiasts, and they can have a substantial impact on the tree’s health as well as put it at risk of dying.


Having access to high-quality nutrients can cut down on the amount of time it takes for a bonsai tree to mature. This can be accomplished by fertilising with balanced bonsai feed on a regular basis during the growing season. In the winter, a lower nitrogen feed is recommended.

Pruning/Disease Control

One of the key reasons why a bonsai tree can develop faster than a full-size tree is because of this. Bonsai trees are continually pruned and inspected for diseases, pests, and root rot, allowing them to remain in excellent health and promote development.

Pests and Diseases

Make sure your trees are potted with the proper soil composition, understand how and when to water them, and you don’t over or under fertilise, and check whether your Bonsai is properly placed. It is most typically the result of continuous overwatering, overfeeding, or underfeeding when the leaves eventually turn yellow and die. Viruses can be identified by discoloured leaves and branch dieback. To avoid cross-contamination, keep the diseased tree isolated from your other trees. Remove affected sections of the tree and spray with a fungicide to treat. Aphids, spider mites, mealybugs are some of the insects that are commonly found on bonsais.

Fastest growing bonsai tree

-There are around 100 species of willow trees, with the weeping willow being the most ideal for bonsai. With proper care, these trees can survive for more than 100 years.
