I have a KATSURA TREE Cercidiphyllum japonicum on the way in the post. I have been advised that it is \\\\\\\"ideal for small or large gardens or for Bonsai\\\\\\\", but also that it may grow up to 5 - 6 - 10 metres in 15 years, which is FAR too big for my garden. I have also been told that it is a 29-25cm talk plant with so branching and you can grow it as a bonsai (make a bonsai of it) or just grow it as a standard specimen (you can cut off any unwanted shoots). How do I keep it at a reasonable size and ensure that it does not take over? Please help! I love the look of the trees, but am terrified I may uproot the house!!!! Many Thanks, Seonad
A Katsura tree can reportedly be grown as a bonsai, on the larger end of what would be considered bonsai. Typically it would be kept in a container and pruned in a specific way for this technique. Bonsai tends to be a more advanced technique, so you should seek out bonsai gardeners in your area or from bonsai groups online for more guidance.
Here are our articles on Bonsai, but these are not specific to the Katsura tree:
Or, if you want more of a medium-sized tree, you could plant it in a large container buried in your yard to keep the roots from growing too large. Frequent pruning could also keep the tree smaller, but you should also seek help from an arborist or other expert, since pruning too hard can ruin a tree's shape if it's not done right.
