The trumpet tree (Catalpa bignonioides) can reach considerable dimensions - the tree grows up to 18 meters high in good conditions and reaches a crown width of up to 10 meters and more. So it's no wonder that many a garden owner has to look for a new location for the impressive tree because the old one is simply too small. But there are also other reasons that speak for transplanting - for example because the tree does not feel comfortable in its previous place or because Verticillium wilt has broken out there.

If the trumpet tree is still small, it can usually be transplanted without any problems

Younger trumpet trees can often be transplanted without any problems

Up to the age of about four to five years, the tree can usually be transplanted without any problems, after which it could become difficult simply due to the sheer size of both the above-ground and underground parts. The main problem here is the fine thread roots, which are of great importance for the well-being and survival of the tree, but are often severely damaged when transplanted. These roots are mainly located on the edges of the rootstock, i.e. very far away from the trunk and are therefore particularly at risk. Improper transplanting can result in the death of the trumpet tree, which is why basic preparation is imperative - the older the tree, the more important.

Transplanting can cause temporary growth arrest

Despite all precautions, transplanting can cause a shock, which sometimes does not necessarily lead to the death of the trumpet tree. Instead, as a result, it can stop growing - and often stop flowering - and often remain in this state for several years. In such a case, only patience and careful care will help. Growth will resume once the tree has established itself in its new location and has once again developed a strong rootstock.

Transplant trumpet tree - That's how it's done

The best way to transplant a tree is as follows:

  • In spring, dig a trench around the root disc of the trumpet tree.
  • This should be about 30 to 40 centimeters deep and about 10 centimeters wide.
  • The stitch should be performed at a slight angle towards the tree.
  • The circle is made larger in diameter the older the tree is.
  • Finally, transplant the tree the following fall.
  • The actual transplanting always happens at best in the leafless period.

tips

A few months later - in spring - you should cut back the above-ground shoots by at least a third.
