Crab Apple (Malus) Bonsai Tree: How To Grow and Care

Sharing is caring!

Growing up, there was a good chance you had a crabapple tree somewhere near your home – at least, if you lived in a temperate area of the Northern Hemisphere, that is. 

The word “crabapple” refers to a genus of more than 50 species of small shrubs and deciduous trees in the Rosaceae family, including regular culinary and eating apples along with wild apples, too. 

However, there are a few species of crab apples that are particularly well-suited to being grown as bonsai specimens. Not only do these plants put on gorgeous foliage that will make you want to stop and pay attention, but they can easily be trained to take on a unique form in your container, too.

If you want to grow crabapple bonsai, this guide will tell you everything you need to know.

There are countless types of crabapple bonsai plants you can grow. After all, no two apple trees are alike – so neither are two crabapple trees! 

Some of the most popular crabapple types for bonsai include Malus halliana, Malus x zumi, Malus toringo, Malus sylvestris, Malus baccata, Malus cerasifera, and Malus floribunda. 

The list doesn’t end there, though – you can use just about any kind of regular crabapple tree for bonsai.

Growing Crabapple Bonsai from Seed or By Propagation

You can grow this plant from seed or by propagation. You may use cuttings as well as air-layering to accomplish this task.

How To Care for Crabapple Bonsai

You can take care of your crabapple bonsai tree using these tips.

Sunlight

Crabapple bonsai needs to be placed in a location that provides plenty of sunlight and airflow. The best spot to place your bonsai tree is outdoors, if the weather permits.

This plant doesn’t like extreme heat or extreme cold, so avoid exposing it to those conditions. It’s a frost-hardy plant, but you do need to protect it from hard frosts, so bring it indoors when the temperatures dip.

Watering

Crab Apples need a lot of water during the growing season. It is very important that you don’t allow your tree to dry out. Your plant will need more water during sensitive times, such as when it is producing flowers or fruit.

If you don’t supply your plant with sufficient amounts of water, it won’t hang on to its flowers or fruit (though fruits are rare on small bonsai plants anyway). 

Try not to use water that is overly acidic, as apples prefer more alkaline or neutral water and soil. 

Fertilizing

You can apply an organic fertilizer once a month to your plants. A liquid fertilizer can also be used, but more frequently – usually, once every three weeks.

Don’t use a nitrogen-rich fertilizer, as this can prevent blossoms as the plant will be encouraged to put on more foliage. 

Potting and Repotting 

You will need to repot your crabapple bonsai each year in the spring. Once your plant is a few years old, you can get away with less frequent repotting (just once every two or three years should suffice).

Prune the roots when you repot and make sure you use a pot that is slightly larger than the original. It should contain soil that retains water easily.

Pruning a Crabapple Bonsai

You should prune your crabapple bonsai in the late fall after all of its leaves have fallen. This will provide the best window for you to identify new leaf buds and flower buds so you won’t accidentally prune away all of the necessary buds. While your plant is in the midst of the growing season, trim back your new shoots to just a couple of leaves. 

Pests and Diseases

This plant is prone to several pests and diseases, just like all other members of the apple family. It can be attacked by pests such as scale, aphids, mealybugs, and caterpillars. These are relatively easy to remove by hand when you spot them, but you can also keep them away with insecticides.

When it comes to disease, watch out for fungal problems like rust and mildew. Canker is another common problem. You can use a copper fungicide to prevent these issues, but often, it’s just easier to maintain good practices in terms of watering and airflow to keep your plants healthy.

Where to Buy Crab Apple Bonsai

You can purchase a crabapple bonsai from many online retailers. It’s often easier to purchase this plant from seed, although it can take a long time for them to get started.

However, since you can grow a crabapple bonsai from just about any cultivar of crabapple tree, you will have a variety of choices when it comes to finding the right fit for your bonsai collection.
