Does the bluebell tree often suffer from diseases?
In principle, the hardy blue-bellied or imperial tree (bot. Paulownia) is considered to be quite robust and resistant to many diseases and pests. However, the rather tasty leaves are not only interesting for humans but also for predators like snails.
The young shoots are also eaten by snails. This may make your bluebell tree unsightly over time. Then you should cut it back thoroughly. You do not have to use chemistry against the snails. Often it is enough to collect the gluttonous animals.
Another danger to your bluebell tree is fungal disease. Fortunately, they are not very common. Here only helps a generous cut off of the affected areas (shoots or leaves), so that the fungus can not spread further. Thoroughly clean your cutting tool to prevent transmission to other plants.
Why does not my bluebell tree bloom?
There can be different reasons why your bluebell tree does not bloom. The first reason could be the age of Paulownia, because it blooms only at the age of about three to five years. But as the bluebell tree grows very fast in the first few years, flowering is often expected.
Another cause of the absence of flowering is frost. The buds form namely already in the fall. If the winter is very cold, then they freeze. Unfortunately, the bluebell tree will not budge the new buds until next fall and you will have to forego the wonderful flower for a year. Remedy only provides protection against the cold or the frost-free wintering of a small tree.
Pruning your bluebell tree regularly, be sure to cut it if possible before applying the new buds. Although a later cut does not harm the tree, there is a risk of involuntarily removing the flower buds.

If your bluebell tree does not bloom, it's probably not a fault but a cold winter. Protect your tree from excessive frost.
