It is possible to convert a tree into a bonsai, but it is an extensive process that many gardeners try to avoid. There are several factors to consider when turning an in-ground tree into a bonsai.
Think Young. Sapling trees are the ideal tree size for anyone who wants to create a bonsai tree. Age is an important factor when choosing a tree. Depending on the species, some trees develop large root systems quickly. If a tree is too old, pruning its roots may kill it quickly rather than preserve it.
Know Your Type. Some tree species do not react well to root pruning and restrictions. These are the core practices of bonsai. Before choosing just any tree, research which trees can withstand aggressive root and branch pruning.
Size Matters. Not all saplings are ideal for creating a bonsai. Look for trees that have proportional parts for easy pruning. Observe the proportions of the trunk, branches, roots, and leaves. Ideally, the sapling will have smaller leaves or needles and attractive bark. Avoid trees with narrow trunks. You’ll want a trunk with a natural tapered look. That means it is wide on the bottom and gradually becomes narrower at the top. Check the branches and ensure that the lower branches are longer than the higher ones. Choosing saplings with the appropriate structure is essential for creating a bonsai.
You can purposely plant a tree in the ground to turn it into a bonsai. As mentioned above, many enthusiasts start a bonsai tree in the ground so it quickly develops a thick and tapered trunk. In this instance, you would monitor the tree and pot it when the trunk thickness is sufficient.
When you’re ready to dig up the tree, it’s best to wait when it’s in its dormancy period.
- Gently work to lift the tree.
- Cut off the main root and some of the smaller roots around it.
- Plant the tree in a loose compost full of sand so you can easily access the dominant main root in the future.
- Prune the branches and foliage to the desired shape and form.
- Continue to maintain and prune the tree as necessary.
