Bonsai Tree Care Guide – How to Grow Bonsai for Beginners

The art of growing and cultivating Bonsai trees is well over 1,000 years old. This tends to scare some people off because they believe that these unique plants are very difficult to maintain. The most popular way to get a Bonsai is to buy one already grown online, but this can be expensive. It’s more cost-effective and rewarding to grow your own Bonsai art form.

In this Bonsai tree care guide, we will give you all of the knowledge and tools you need to successfully take a creative role in growing and maintaining this beautiful plant. 

What is Bonsai?

Bonsai is the Japanese art of recreating nature in miniature. These miniature living works of art make for a great combination of style and grace, and are sometimes also known as dwarf trees.

The term “Bonsai” literally translates into “potted plant.” But, there is a broad range of bushes, plants, and Bonsai trees that you can train to keep as a Bonsai.

An Introduction to Bonsai Trees

Typically associated with Japanese culture, the Bonsai tree originated in China. Eventually, these Bonsai trees became symbolic of the Zen Buddhism religion. However, the Japanese did improve and help develop the art of growing the Bonsai trees you see today.

Today, Bonsai trees are typically kept for recreational and decorative purposes. There are therapeutic values associated with growing these Bonsai trees, and it teaches patience. The ancient Chinese believed that anyone who could care for Bonsai trees for a long time would gain eternity for their soul.

Unlike the widespread belief, Bonsai trees are not actually genetically dwarfed plants. Instead, there is a specific series of techniques and steps that stunt the plant’s growth while allowing them to live as long as their counterparts. You can grow any tree as a Bonsai, but there are several steps you have to take into consideration to get there in your Bonsai tree care journey.

Pick the Correct Species / Type of Bonsai

Did you know that there is more than one species of these plants and some are easier to grow than others? Additionally, some do better indoors or outdoors. This is why it’s so important to choose the correct tree species or type of bonsai from the start. Consider the climate your plant will be in. For example, some tree species require the temperature to go below freezing so they can enter a dormant state while others will die if the temperature dips too low. Some require more humidity than others, and some need special Bonsai soil conditions, while others need moderate temperatures throughout the year. Also, some species are more prone to insects and disease than others, and this makes them more challenging to grow.

Juniper trees are very beginner-friendly. They’re very hardy, and they can survive the temperate regions of the southern hemisphere and all over the northern hemisphere. They respond very well to training efforts like pruning, and they don’t lose their leaves. However, they grow very slowly.

Spruces, pines, and cedars are three other relatively easy species to grow and cultivate. Japanese maples are very beautiful, and so are oaks, elms, and magnolias. If you live in cool climates or want to grow your Bonsai indoors, non-woody tropical species like jade are a good choice. If you’re not sure, ask at your local nursery.

Indoor or Outdoor Bonsai Trees

Once you decide on a species, choose whether you want the plant to live indoors or outdoors. You don’t want to send it into shock by moving it between these two areas. Indoors is usually drier and has less light, so your indoor Bonsai tree will need less moisture and light to grow. I picked out several varieties for both indoor Bonsai tree and outdoor Bonsai tree growth for you below.

  • Indoor Bonsai Trees – Camellia, Ficus, Gardenia, Hawiian Umbrella, Kingsville Boxwood, and Serissa
  • Outdoor Bonsai Trees – Beech, Birch, Cedar, Cypress, Elm, Ginkgo, Juniper, Larch, and Maple

Several different species of Bonsai trees you can choose from to grow your own depending on your location and climate.  

Starting Bonsai Trees from Seed

First up, I’m going to outline how you would start a Bonsai tree from seed. You’ll need patience to go this route because it can take three to five years of care before your Bonsai tree gets big enough to start shaping. However, it’s worth it when you can see the fruits of your labor pay off and your Bonsai trees thrive.

1. Get Your Seeds

Try to get fresh seeds for your plant. The window of time that these seeds are viable for germination is shorter than typical vegetable or flower seeds. Oak seeds are best when you harvest them in early autumn, and they need their green color.

Deciduous Bonsai trees like maples, oaks, and beeches have seed pods that are highly recognizable. They shed these seeds each year, and they’re very easy to get your hands on. This is why they’re so popular for anyone who wants to start an indoor Bonsai tree from seed.

2. Let the Seeds Germinate

When you gather up your seeds (and you should gather several), you have to care for them so they sprout. If you live in a non-tropical area and you have defined seasons, seeds usually fall in the cooler autumn months. Then, they go dormant until spring. You have to mimic colder temperatures for a few months before gradually warming them up to mimic spring weather.

If you live in an area that has defined seasons, bury your seeds in a pot of soil mixture and set it outside throughout the winter and into spring. If not, put your seeds in a bag with a slightly damp growth medium like vermiculite. Leave them in the refrigerator until spring, and remove them when you see them start to sprout.

When they’re in the refrigerator, start them at the bottom. Over the course of two weeks, slowly move them up until they get to the top shelf. This will stimulate temperature fluctuations. Come spring, reverse it and move the seeds down the shelves until you get to the bottom.

3. Plant the Seeds in a Starter Pot

Once you see sprouts, you can place the seedlings into a start pot or tray. If you germinated your plant outside, you can leave it in the pot. If not, buy a starter tray and fill it with rich soil. Dig a hole and place the seed in so the sprout points up and the root system faces down.

Water it right away. Try to keep the soil mixture damp, but avoid overwatering. You should avoid using fertilizer for five to six weeks. After this time passes, use a very small amount to give you plant a boost, and avoid getting it on the leaves. Amazon has starter trays available if you can’t find them at your local nursery.

This starter kit comes with 15 trays with 10 cells each. It uses a biodegradable material that helps retain soil moisture to keep your plant healthy. It’ll break apart to allow for the plant’s roots to break through the bottom and continue to grow. 

As your seedlings start growing, it’s essential that you carefully monitor the temperature. Cold will kill any growth, and you’ll have to start over. Tropical Bonsai tree species do better in greenhouses. Just make sure the Bonsai trees are in a semi-shaded spot and keep the moist.

4. Care for Bonsai Trees

Keep watering and giving your Bonsai tree seedlings semi-sunny conditions as they grow. Once you reach this stage, it’s a year-round project. By year four and five, you’ll start to get a plant that you can train. Tropical species should stay inside, but if you picked a species that can survive in your location, you can set it outside in a space it gets morning sun and afternoon shade.

Potting a Grown Bonsai

If you decide to skip growing your plant from seeds, you can purchase grown Bonsai trees from an online store. Some specialty greenhouses have them available as well, but they are more expensive. You’ll want to put it in a different pot when you get it to allow for growth as you take care of it.

1. Remove the Whole Bonsai Tree and Clean It

Carefully remove your Bonsai tree from its current pot without breaking the stem. You’ll cut a lot of the roots before you put it into a new pot, so don’t worry about them as much at this stage. Once you get it out, carefully brush away any stuck-on dirt that blocks your view of the roots. You want to clean enough dirt away so that you can see what you’re doing when you start to prune them. They don’t have to be spotless.

If you don’t control your Bonsai’s growth, it can outgrow it’s container. This is why you’ll prune the roots before you repot it to help keep it small, tidy, and neat. Cut away any upward-facing roots, or roots that are overly large. You want to have slender, long roots left that will stay close to the surface of the soil. This is how your Bonsai tree absorbs water, and it works well in small pots.

2. Get Your Pot Ready for the Indoor Bonsai Tree

Add a fresh new base of soil to the new pot. This will give your Bonsai tree a better height. There should be a thin layer of coarse-grain soil in the bottom of the pot to help it drain. On top of this layer, add a loose, fine layer of growing medium. It should drain very well, so avoid regular garden soil. Check and see if your indoor Bonsai came with a recommended bonsai soil. If so, use this.

3. Add Your Tree to the Pot

Carefully position your tree in the pot. Add in a thin layer of well-draining, dry soil mixture to cover the roots. You can add a layer of moss as well to help hold it in place and give it a pop of color. It’s also a good idea to install small mesh screens over the pot’s drainage holes. This will prevent the bonsai soil mixture from eroding over time. If it won’t stand upright, you can run a wire from the draining holes up through the root system.

4. Care for Your New Bonsai Tree

Leave your Bonsai trees in a semi-shaded area for two to three weeks after you repot it. Water the plant to keep the bonsai soil mixture moist, but avoid fertilizing it until the plant’s roots have time to re-establish themselves. This time will help you tree adapt to the new pot. If you have a deciduous species, repot it in the spring for best results. Bonsai trees require repotting every two to five years, while deciduous Bonsai trees require repotting every two years.

You can add smaller plants to the pot if you’d like after a few weeks to create an aesthetically pleasing look. This is completely optional.

Bonsai Training

Now that you know how to plant, grow, and care for Bonsai trees, I’ll go over how you train Bonsai trees. Wiring and pruning are necessary to keep your plant healthy and thriving. It can be intimidating for new growers, but it’s a relaxing process that allows you to shape your tree.

Pruning Your Bonsai

You prune your tree’s branches to maintain it, and you prune it to shape it. Maintenance pruning takes place during your tree’s growing season in the spring and summer months. Each species has a different pruning routine. However, you generally want to get rid of any leaves that are too large for your plant. If you have vertical branches that are too big to shape, prune them away. Cut as close to the body as you can to remove the most stray branches.

When you remove the branches, you want to apply a healing paste to the cut area. These pastes work to stop disease from reaching your Bonsai, and it encourages it to stay healthy. Amazon has the CUTPASTER Bonsai Cut Paste available that works well. Once you prune it, give it a few weeks to recover. Trim the roots when you give your Bonsai a maintenance trim to keep your tree miniature. If you don’t, the tree will grow a huge amount to try and grow the branches that you cut away back.

The CUTPASTER Bonsai Cut Paste is a thick paste that adequately seals any cut areas on the plant to lock out diseases and encourage healing. It can protect an area for over a year with one application, and it’ll allow the plant to form a callus after one or two months to complete the healing process. 

For shape pruning, the goal is to get a balanced look for your tree. Don’t take a lot off one side and not a lot off the other. This can lead to a lopsided look. If you have two thick branches that are the same height, trim one away. Get rid of any thick branches on the top of the Bonsai, and cut away and branches you can’t twist. If you added smaller plants to the indoor Bonsai container, don’t forget to prune those too to keep them healthy.

Bonsai Wiring

Wiring your Bonsai allows you to bend and curve the branches, and you use either aluminum or copper wire. You have to keep a careful eye on it and be very careful in general because you can injure your tree. Also, remove the wiring after you get the results you want. Bigger branches will need thicker wire, and it’s best to wire your Bonsai during the growing season from early spring to autumn.

To start, anchor your wire to the tree’s base or the pot. Decide which branches you want to train to grow in a specific direction. Start with the thicker branches and wrap the wire around them, leading them into the shape you want them to stay in. Wire branches that are the same size together. If you want to do the whole Bonsai at once, start from the trunk and work your way out.

Once your Bonsai tree gets into the shape you want, carefully remove the wire. Allow your Bonsai tree to rest and recover for three to four weeks.


This is what a Bonsai tree looks like when you use wire and correct pruning techniques in Bonsai tree care. You can make the tree grow in any direction you wish, and the pruning adds balance while making it seem full. 

Bottom Line

Hope this Bonsai care guide was useful. Growing a Bonsai tree is a labor of love that requires patience and dedication on your part. However, I’ve outlined all of the basic Bonsai tree care and growing techniques you need to try with a Bonsai of your own. If you don’t succeed the first time, try again. Bonsai tree care takes time to learn the art of Bonsai growth and maintenance, but the beautiful results of your bonsai care are well worth it.
