Common problems with kalopanax septemlobus and how to solve them
Kalopanax septemlobus is a highly attractive, yet challenging deciduous tree to grow and maintain in the UK’s climate. As it is known for its aesthetic appeal, with its lush foliage and beautiful, textured bark, many UK gardeners are keen to add it to their outdoor space.
Unfortunately, as many of us know, maintaining a healthy garden can often come with unexpected difficulties, and it is no different when it comes to growing and caring for Kalopanax septemlobus. The most common problem facing owners of Kalopanax septemlobus is that this tree cannot tolerate frost; its delicate leaves can quickly become scorched by temperatures even slightly below freezing. Overwintering can be a difficult challenge, as it is essential to protect the tree from harsh, frosty weather.
Mulching with a layer of organic material, such as bark or straw, can provide some insulation, while evergreen foliage can also help to keep the sun off the soil during the winter months. Another common problem associated with Kalopanax septemlobus is its propensity to drop branches.
This tree has dense foliage and can grow very quickly, meaning it becomes top-heavy, causing excess weight on the branches which can then fail under the strain and will then have to be removed. Additionally, it is important not to prune off too much foliage as this can destabilise the tree’s balance and can encourage more branch loss. Instead, opt for thinning out any overly dense areas and dead wood as this will ensure that the tree is able to remain healthy and structurally sound.
In summary, growing and caring for Kalopanax septemlobus can be challenging, but with the right knowledge and preparation, owners will be able to have an attractive, thriving tree year-round. Knowing how to protect the tree from frost and properly prune it is essential, to ensure that it remains healthy and robust, even in the most uncertain of conditions.
