Pre bonsai trees are young trees that have not yet been styled or trained into the traditional bonsai form. These trees are typically between 2 and 4 years old and have not yet been pruned or wired. Pre bonsai trees are a popular choice for bonsai enthusiasts who want to start with a younger tree and have more control over the shaping and styling process. In this article, we’ll explore what pre bonsai trees are, how to care for them, and the steps you can take to transform them into beautiful bonsai trees.

What Is a Pre-Bonsai Tree

A pre-bonsai tree is a young plant that has started receiving preliminary training for its future development into a mature bonsai. These trees can be seedlings, saplings, or older trees that have not yet been shaped into their final bonsai form (source).

Pre-bonsai plants are often the first choice of beginners who want to learn the art of bonsai from the ground up. The process of nurturing a pre-bonsai tree involves several essential steps, such as root pruning, trunk thickening, and trunk shaping (source). This early training helps prepare the trees for their eventual transformation into mature bonsai masterpieces.

As the tree advances through the bonsai training process, it is referred to as being in the ‘pre-bonsai’ stage. With patience and skilled care, these pre-bonsai trees will eventually take on their envisioned form, complete with a thick, aged-looking trunk and meticulously shaped branches (source).

Pre-Bonsai Tree Care

Caring for a pre-bonsai tree involves several aspects that contribute to its overall health and development. This section will guide you through the key elements of pre-bonsai tree care, including watering, fertilizing, sunlight, pruning, and repotting.


Watering is a crucial aspect of taking care of pre-bonsai trees. The frequency of watering depends on factors like tree species, pot size, time of year, soil mixture, and climate. However, it’s essential to monitor your tree’s specific needs and adjust your watering schedule accordingly.


Providing essential nutrients to your pre-bonsai trees is vital for their growth and overall health. Regularly apply a well-balanced fertilizer that includes nitrogen, phosphorus, and potassium, with additional micronutrients such as iron and magnesium. Adjust the fertilizer application frequency and dosage based on the tree’s age, species, and season.


Pre-bonsai trees require adequate sunlight for optimal growth. Make sure to place your tree in a location that receives plenty of natural light, and consider the specific sunlight preferences of the tree’s species. Some trees may prefer direct sunlight, while others thrive in indirect or partial sunlight.


Pruning your pre-bonsai tree is essential for styling and maintaining its shape. Regularly trim the leaves and branches to encourage new growth and control the tree’s size. Keep in mind that different tree species may have varying pruning requirements, so it’s important to learn about the specific needs of your pre-bonsai tree.


Repotting is necessary to ensure the health and development of your pre-bonsai tree. As the tree grows, it will require a larger pot to accommodate its expanding root system. Generally, pre-bonsai trees should be repotted every two to three years, depending on the species and individual growth rate.

Selecting Pre-Bonsai Trees

Choosing Species

When starting with pre-bonsai, the selection of a suitable species is crucial. It determines how well the tree will adapt to bonsai techniques and the environment it will be grown in. Research the species that thrive in your region and match your experience level. Some popular beginner-friendly species include the Juniper, Ficus, and Trident Maple trees. Each species has its own unique characteristics, like foliage type, growth rate, and care requirements.

Assessing Health

The health of a pre-bonsai tree is key to its successful development into a mature bonsai. When selecting a young tree or shrub, check for signs of good health such as strong roots, vibrant leaves, and a lack of pests or diseases. Identify any structural flaws, like crossing branches or deadwood, early on in the selection process, as these can hinder the tree’s progress as it matures.

A healthy pre-bonsai tree will be easier to work with and develop into a beautiful bonsai masterpiece. Careful consideration of species and thorough assessment of health are essential factors in the selection process, ensuring a strong foundation for your bonsai journey.(source)

Training Pre-Bonsai Trees

Training pre-bonsai trees is an essential step to help them transition from a young tree to a mature, well-developed bonsai. In this stage, bonsai artists use various techniques to shape the tree and give it the desired aesthetic appearance.

Wiring Techniques

One popular method used to train pre-bonsai trees is wiring. Wiring involves carefully wrapping wire around the branches and trunk to guide their growth in a specific direction or shape. The choice of wire material and thickness depends on the size and strength of the tree’s branches.

When wiring a pre-bonsai tree, it is important to avoid damaging the branches and to allow for growth without constricting it. Regularly monitoring the wired tree and making adjustments as needed ensures that the desired shape is achieved gradually without harming the tree.

Aside from wiring, other techniques such as pruning and pinching can be employed to train pre-bonsai trees. These methods help control the tree’s growth and maintain the desired form.

Benefits and Challenges

One of the main benefits of pre-bonsai trees is the opportunity for individuals to personally train and shape the tree according to their preference. It allows enthusiasts to explore their creativity and create a unique design for their future bonsai masterpiece (HappyyGarden). Moreover, tending to these trees can help cultivate a sense of patience and mindfulness, which can have positive effects on mental health and well-being (Bonsai Prodigy).

However, working with pre-bonsai trees also comes with its share of challenges. Since these trees are still in their early stages and may not yet exhibit all the desired characteristics of a finished bonsai, they often require years of dedicated care and skillful shaping before they reach their full potential (Cleveland Bonsai Club). This commitment to long-term nurturing can be daunting for some, especially for beginners in the bonsai art.

Additionally, proper bonsai care involves various techniques and knowledge of horticultural practices, such as pruning, wiring, and repotting. For pre-bonsai trees, understanding the specific needs of the tree species and adjusting care practices accordingly is crucial for healthy development and growth (Art of Bonsai). This learning curve may be challenging for those new to the art, but with patience and dedication, the rewards of nurturing a pre-bonsai tree can be immensely fulfilling.
