What Is a Eucalyptus Bonsai?

Eucalyptus trees are known for their strong wood and hardy nature. They can live for centuries if they are cared for properly, making them an excellent choice for bonsai enthusiasts who want to create long-lasting art pieces. Eucalyptus bonsai is a type of bonsai tree grown in Australia and New Zealand. These trees are known for their hardiness, as well as their unique appearance.

The eucalyptus is a genus of flowering trees that includes over 700 species native to Australia and New Zealand. The leaves on these trees are roughly circular and can be anywhere from 1 to 4 inches long. Unlike most other types of bonsai trees, eucalyptus bonsai does not have a single trunk; instead, it has multiple trunks growing from one base. The trunks on these trees can grow up to 10 feet tall!

Another interesting feature of eucalyptus bonsai is its bark. When this type of tree reaches maturity, it develops a thick bark that is almost black. It also produces many buds at the end of its branches (called “terminal shoots”).

How to Care for a Eucalyptus Bonsai

Here are some tips for caring for a Eucalyptus bonsai properly.

House Placement

Eucalyptus bonsai are known for their ease of care, low-maintenance requirements, and adaptability to different environments. However, they do require a little extra attention regarding where they are placed in the home.

They can be placed just about anywhere in the house as long as the room has good air circulation. They do not need direct sunlight, but they enjoy high humidity levels, which is why many people place them near a window that gets indirect sunlight. If you have a large eucalyptus tree that is not suited for placement near an open window, you can attach it to your wall with an H-frame bracket or hang it from a ceiling hook or similar fixture.

Watering Requirements

Eucalyptus bonsai are native to Australia and grow in a variety of climates. Their watering requirements depend on your particular climate, but there are some general guidelines you can use to determine when to water your tree.

In general, most eucalyptus trees need to be watered every three or four days during summer and every five or six days during winters. If you have a particularly dry environment or your tree is in a pot with a drainage hole, you may need to water it once a day during summers and once every two days during winters.

The best way to tell if your eucalyptus needs watering is by checking its soil moisture level. You should feel around in the pot. If you can’t feel moisture coming up through the soil, then it’s time to water your tree.

Fertilizing Requirements

Eucalyptus bonsai trees are extremely popular and easy to grow if you know what you’re doing. The first step is to understand what fertilizing requirements your tree has. When caring for a eucalyptus, it’s important to note that they have slightly different needs than other plants. They’re not quite as needy as some other species of bonsai trees, but they still need extra care.

To start with, eucalyptus trees will do best when they’re exposed to indirect sunlight every day. If you live in an area where the weather stays warm year-round and you don’t have any other plants that need protection from the sun, then this shouldn’t be an issue for you.

Another thing to keep in mind about eucalyptus bonsai trees is that they need regular watering but not too much! If your soil is too wet or too dry for long periods, it can cause problems for your plant. Please check on its moisture levels every day or two so that there isn’t too much water underneath its leaves at any given time (and vice versa).

Pruning and Wiring

There are two basic methods for pruning and wiring a eucalyptus bonsai: the initial style and the refinement process.

The initial style involves pruning and wiring the plant to create a shape that will be maintained throughout its life. This is done in three steps: removing unwanted branches, training new branches, and wiring the branches into place. First, you should remove any dead or dying branches from your eucalyptus bonsai by cutting them off with shears or scissors. Deadwood will never grow back, so it’s important not to leave any of it on your plant.

Next, you’ll need to train new branches into place using wire or string. This can be done by wrapping wire around the branch where you’d like it to grow out of its current position, then twisting it around itself until the branch takes root in its new spot (this may take several days). 

If this doesn’t work for whatever reason—for example, if you’ve wrapped too much wire around one spot—you can always unwrap it later on down the line when your branch has taken root in its new position! Finally, once all your branches are trained and secured with wire, you can begin pruning out more.

How do You Repot a Eucalyptus Bonsai?

  1. Remove the old pot.
  2. Place your eucalyptus bonsai in a sink, tub, or bucket filled with water and allow it to soak for 24 hours. This will help loosen the roots and make them easier to remove from the old pot.
  3. Remove any dead or damaged leaves from your eucalyptus bonsai tree and clip off any broken branches that are still attached to healthy tree sections.
  4. Use a trowel to gently loosen the soil around the trunk of your eucalyptus tree so that you can see where its roots are growing from underneath its bark layer. You may need to use a knife or other tool if some of those roots are particularly stubborn! 
  5. Remove any remaining soil from around each root ball and between individual roots using tweezers or another tool that will allow you to get into tight spaces between them without damaging them further than necessary (eucalyptus trees have very fine root hairs that shouldn’t be broken). 
  6. Place your newly potted eucalyptus bonsai in an area where it will receive plenty of sunlight but not direct sun.

Pests and Diseases

The eucalyptus bonsai is a wonderful addition to any home, but it should be cared for properly and protected from pests and diseases to ensure its health. Here’s what you need to know about pests and diseases that can affect your eucalyptus:


Mealybugs are a common pest of eucalyptus trees. They are the size of an ant, with a white body and brown head, and they leave behind a sticky residue on your tree’s leaves. If you spot mealybugs on your plant, carefully remove them by hand or use an insecticidal soap spray.

Scale insects can also be a problem for eucalyptus trees, though these insects are less common than mealybugs. You’ll spot scale insects when they appear as small bumps on the trunk of your tree or as dark spots on its leaves. Remove these insects by gently scraping them off with your thumb or using an insecticidal soap spray (or both).


Fungal Diseases: These are caused by fungi that live in the soil and on leaves and branches. They can spread quickly and kill the plant within a few days.

Viral Diseases: These are transmitted by insects or wind-borne particles that carry the virus from plant to plant. The result is usually a leaf distortion or discoloration, but it can also cause stunted growth, dieback of branches, and cankers on the trunk. 

Final Thoughts on How to Take Care of Eucalyptus Bonsai

The eucalyptus bonsai has a thick and pointed trunk. Its leaves are bluish-green, and its bark is dark and shield-shaped, protecting the tree from unwanted insect attacks and infections. Its flowers are small, white, and round. 

These trees can survive in various climates but flourish in regions with summer rains. The best soil to use is one which has been enriched with compost or well-rotted manure. It is important to prune the eucalyptus bonsai several times a year since the plant tends toward central dominance. These trees can live up to two hundred years, making them ideal as potted specimens for your home.
