How to Take Care of a Juniper Bonsai Tree Indoors

A juniper bonsai tree is a great option for beginners as they are simple to care for. Here, we discuss a few tips on keeping a juniper bonsai tree indoors. If you have a juniper bonsai tree and want to know how to take care of a juniper bonsai tree indoors, this is the article for you!

What is Juniper Bonsai?

Juniper Bonsai is a plant that has been trained to grow in the shape of a bonsai. It is made with various junipers, which can be grown indoors or outdoors. The most common juniper bonsai is the Japanese black pine, but other varieties of juniper are also used.

Junipers are popular as bonsais because they grow quickly and easily, making them ideal for beginners. They can also be grown in containers, making them convenient for those who do not have a lot of space in their homes.

How to Take Care of a Juniper Bonsai Tree Indoors

Juniper bonsai trees are popular for their hardiness, longevity, and unique shape. They can be taken indoors at any time and flourish in various locations. Once your juniper bonsai tree is set up in its new home, it’s time to learn how to care for it.


The first thing you need to do when taking care of a juniper bonsai tree indoors ensures that you have the right humidity level in your house. The best way to do this is to check with a hygrometer and adjust your home’s humidity accordingly. If you have a humidifier, use it!


Juniper bonsai trees are hardy plants that can handle a wide range of temperatures. They need to be kept out of direct sunlight, but they don’t mind if it’s cold and dark. They prefer the dark.

Junipers thrive in temperatures between 50 and 55 degrees Fahrenheit, so you’ll want to keep your juniper bonsai tree out of direct sunlight and away from heating vents. If you have a heat vent, place your tree on the opposite side of the vent (so it’s not directly in front of or behind it). It would be best if you also tried to keep your home at a steady temperature so as not to subject your tree to drastic fluctuations in temperature.


The best way to provide sunlight for your bonsai tree is by positioning it near a window that receives direct sunlight for at least 2.5–3 hours per day. If you don’t have enough natural light through your windows, you might need to use artificial lighting during winter.


Finally, watering your juniper bonsai tree will be important for keeping it alive indoors. Ensure that water drains freely from its pot after watering so it doesn’t cause root rot—and be sure not to overwater! Only water when the soil has dried out completely (you can check by sticking your finger down into the soil).

Feeding Your Plant

Feed your juniper bonsai trees once every two weeks during the spring and summer with an all-purpose fertilizer formulated for indoor plants. During the fall and winter months, feed them once every three months with a specially formulated fertilizer explicitly designed for bonsais (such as Miracle-Gro Indoor/Outdoor Fertilizer). Be sure not to overfeed your plant with fertilizer; too much can cause leaf burn or root rot which could kill it!

Pruning Your Juniper Bonsai

Juniper bonsai trees must be pruned regularly to stay healthy and strong, but don’t overdo it!

Remove Unhealthy leaves

Remove any browning or yellowing leaves, as they could be diseased or infested with pests like spider mites (which can damage your plant’s health).

Root Pruning

If your juniper bonsai tree has been in the same pot for a while, consider root pruning it. The best time to do this is in late winter or early spring. First, remove any dead or dying foliage from the top of the plant. Then, cut back the roots to about one inch from the bottom of the root ball.

If you have repotted your juniper bonsai recently, you won’t need to worry about insect control for now.

Insect Control

If you see ants or other insects on or around your juniper bonsai, use an insecticidal soap spray to help control them.

The Challenge of Growing Juniper Bonsai Trees Indoors

Growing a bonsai tree indoors can be a challenge, but it can also be gratifying. If you have been trying to grow a juniper bonsai tree inside, you may have found that it is more difficult than other bonsai trees. There are several reasons why this is so.


One reason is that juniper bonsai trees require more sunlight than other bonsai species. They need to be placed in an area where they will receive at least 3 hours of direct sunlight each day. While growing the trees outdoors during the summer months is possible, you must bring them back inside before the first frost hits.

If your home does not get enough natural light or if you do not have room for a full-sized juniper tree, consider using artificial light sources such as fluorescent lights or full-spectrum lamps. You may also want to invest in some shade screen or reflective material to help diffuse light from windows or other sources so that it doesn’t become too hot for your plant.


Another challenge when growing juniper bonsai trees indoors is temperature control during winter when temperatures tend to drop below freezing outside (or even just into single digits). The climate inside your home may also vary, depending on where you live and whether you have a central heating system or not.

If you’re trying to grow your juniper bonsai tree in a cool climate, you’ll want to keep the temperature around 55 degrees Fahrenheit. That’s about 12 degrees Celsius for our European friends out there. You’ll also want to ensure that the humidity level stays high enough, so the soil doesn’t dry out too quickly.

If you have a central heating system or live in an area with mild winters, keeping your juniper bonsai tree alive throughout the year should be easier. However, some things can still go wrong if you don’t care for them properly!

Advantages of Juniper Bonsai

It’s beautiful

There are wide varieties of junipers available on the market, which come in different colors like blue, green, and yellowish-green, making them more attractive.

It’s low maintenance.

The only thing that you need to keep doing is to keep it watered regularly. Otherwise, this plant can survive without being watered for months if kept in the correct environmental conditions, such as temperature.

It’s easy to grow

Juniper bonsai grows very slowly, so you don’t have to worry about regular trimming or dead branches, unlike other plants like shrubs or trees, which grow faster and need regular trimming or removal of dead branches from time to time to keep them healthy and looking good.

Grow quickly

The Juniper Bonsai grows quickly when cared for properly, so it will grow into a full plant within just a few months!

They grow well indoors or outdoors.

You can keep them in a pot on your windowsill or put them outside in the summer and bring them inside in the winter.

As gifts

If you’re looking for a unique present for a friend or family member, juniper bonsai makes an excellent gift!

Great for decorating!

Juniper bonsai trees look beautiful when decorated with lights and other holiday decorations or on other special occasions.

Juniper Bonsai Has Some Disadvantages

  • It requires pruning, so you have to know how to do that.
  • It needs a lot of sunlight, so it’s not ideal for those with a lot of shade in their home.
  • The juniper bonsai is poisonous to cats and dogs if they chew on it or eat any part of the plant.
  • A Juniper bonsai has a short lifespan.
  • They can be expensive to buy and must be repotted every year.


1. How long can a juniper bonsai live indoors?

It’s hard to say exactly how long your juniper bonsai tree will live. Still, it can generally be kept indoors for approximately two years before becoming too large for its container and needing to be repotted in a larger pot. After that, it will need to be transferred to the garden or greenhouse—but if you’re not sure how long to keep your juniper bonsai inside, you may want to keep it in the house for another year or two.

2. Should I mist my juniper bonsai?

It depends on what kind of soil mix you’re using! If your juniper bonsai is planted in a small container and growing in a soil mixture with good drainage, then misting shouldn’t be necessary. If you’re using a large, heavy pot with an organic soil mix that retains water, misting is recommended because it will help keep the soil moist without making the plant vulnerable to root rot or mold.

3. What do I feed my juniper bonsai?

Juniper bonsai trees are very easy to care for and can thrive with the right amount of sunlight, water, and air circulation. However, they need good fertilizer every few months, especially if you want your bonsai to proliferate or look its best. You can choose between organic and synthetic fertilizers; both will work well. The key is to use a fertilizer made explicitly for bonsai trees so it won’t burn the roots or soil.

4. How do I know if my bonsai tree is healthy?

The best way to tell if your juniper bonsai tree is healthy is by looking at its leaves and buds. If they’re a healthy dark green color and feel smooth underneath, then chances are good that they’re doing well! If they seem unusually pale or discolored, or if there are any brown spots or holes on them, this could indicate that something isn’t quite right with the plant’s environment.

5. Which Bonsai is best for indoors?

The best bonsai trees for indoors are those that don’t need too much water or sunlight—like juniper or ficus trees. These plants will grow well in the right environment and can thrive on little care from you!

6. What does an overwatered bonsai tree look like?

An overwatered bonsai tree will have a weak, droopy appearance with yellow leaves and brown spots. The trunk will be mushy and soft, and the soil will be moist but not wet. If you see any of these signs in your bonsai, it’s time to let it dry out.


One of the most important things about juniper bonsai trees, especially indoors, is watering. You never want to overwater your juniper bonsai tree because that can kill it. It’s essential to know the right time to water it. If your soil is dry and you can somewhat easily wiggle the soil out of its container without having to scrape it, then that means that your tree needs more water.
