The blue bell tree lives up to its name during the flowering period, because the pink-violet to blue flowers stand upright like bluebells in umbels up to 40 centimeters long and have an intoxicating scent. However, it is not easy to maintain.

Especially young paulownia have to be watered regularly

The ideal location

Warm and dry is the ideal location for your bluebell tree, which is also known under the names Kaiserbaum or Paulownia. He does not tolerate cold wind, least of all in winter. Due to its imposing appearance, the blue bell tree should be planted as a solitaire, and the spreading crown also requires a lot of space. Paulownia tolerates drought and heat relatively well.

What soil is best for the bluebell tree?

The bluebell or emperor tree originally comes from China. He likes a moderately dry to slightly fresh and not too poor soil. This may be slightly acidic to alkaline and should not promote waterlogging. If the soil is too moist and loamy, the young shoots of your bluebell tree will not lignify in time.

Water and fertilize the bluebell tree properly

Although the blue bell tree has a fairly high water requirement, an older tree can cover this quite well on its own. Its roots are widely branched. A young tree, on the other hand, should be watered regularly, especially in summer. In spring and/or summer, the bluebell tree is grateful for a dose of mature compost.

Pruning the bluebell tree

The blue bell tree tolerates a pruning quite well, even if this turns out to be a bit radical. It is best to prune your tree between May and July before it forms its new buds. Frost-damaged shoots can be cut off in spring.

The bluebell tree in winter

A young bluebell tree is not yet hardy. It definitely needs adequate winter protection. Since the flower buds form in autumn, the blue bell tree is somewhat susceptible to late frosts. These occasionally freeze the buds.

The essentials in brief:

  • Location: warm, dry and sheltered from the wind
  • Soil: loose, permeable, moderately dry to slightly moist
  • Regular pruning makes sense, ideally between May and July
  • very resistant to diseases and pests

tips

Only plant a bluebell tree if you can give it enough space.
