Selecting The Right Bonsai Nutrients And Soil For Your Bonsai Tree. The proper soil and pot for your bonsai trees can provide it with necessary nutrients, retain water, and also have an important impact on its overall health.

What type of soil is ideal for a bonsai tree? Well, there isn’t really any particular kind of soil that’s “right” or “wrong” for any one bonsai. What’s more important is that your soil and pot provide the ideal combination of elements that the plant needs to stay healthy. Some factors in consideration are the species of the tree, as well as the size and shape of the pot.

Trees For Both Decoration And Practicality

If you’re growing trees for both decoration and practicality, a bonsai pot made specifically for the species you’re growing is ideal. On the other hand, some bonsai trees grow best in pots with large leaves and exposed branches. For most other trees, you should consider one with a larger opening. For example, if you’re growing an ordinary tree species, you should consider buying one with an open air space of between ten and fourteen inches. On the other hand, open air spaces of between eight and ten inches are ideal for ficus and azalea trees.

The size and shape of your container also play a part in bonsai trees, no matter what type of tree you’re growing. Some varieties need tall containers that are wider and deeper than others. However, keep in mind that a wide container will be more easily destroyed by insects and other animals, so it’s always better to choose a miniature version. Likewise, some bonsai trees grow better when they’re planted in shallow containers, while other species grow better in deeper containers. Another factor that affects your bonsai tree’s health is the moisture content of your pot; conversely, too much moisture can encourage root rot and root breakage, which can negatively affect your entire bonsai collection.

How Much Time You Plan To Spend Inside

You should also consider how much time you plan to spend inside your bonsai house. Some bonsai trees require constant partial sunlight, while others need only partial sun. You should also think about whether you’re going to place your pot in a sunny window or in a shaded corner of the house.

Bonsai pots made from fiberglass and acrylic are a popular choice for bonsai trees. These types of pots are usually wider and deep enough to withstand high temperatures. Because they don’t retain moisture well, the color of your tree won’t fade as easily over the years. However, they can still crack, especially if you place your tree in a pot without a protective cover. Some bonsai pots also come with nets at the bottom of the pot, which prevent soil erosion and help contain water.

Potting Soil

Potting soil blends should be used carefully. Different kinds of tree require different amounts of fertilizer. Some bonsai trees require one tablespoon of fertilizer per pound of tree, while others may need up to two cups. 

Your local garden center can recommend the best combination of fertilizer and soil based on the type of tree you have. For example, an azalea bonsai requires fertilizer that’s lighter than any other bonsai trees.


The best time to prune your bonsai trees is in the late winter or early spring, after the weather has warmed up a bit. Remove all the leaves off your bonsai, including the ones on the branches, and remove any broken bark or splinters from the branches. Prune your trees until all of the saplings are approximately one to two inches tall. Then, empty out the bonsai pots, add some new soil blends, and put your tree back in the bonsai pot.
