In contrast to the conventional trumpet tree, the ball trumpet tree (Catalpa bignonioides) forms a more spherical crown, which, however, can become very wide over the years. In addition, this type of trumpet tree remains significantly smaller, up to six meters high. What is impressive, however, is the beautiful blossom.
How do I care for a ball trumpet tree?
To successfully care for a globe trumpet tree, place it in a sunny and warm location with permeable, nutrient-rich substrate. Plant it late in spring and in a mild area to avoid frost damage. Container keeping is recommended for young specimens.
Which location does the ball trumpet tree prefer?
The globe trumpet tree loves the sun and warmth and should therefore be given a warm and sunny location. However, young specimens in particular cannot tolerate frost.
In which substrate should the globe trumpet tree be placed?
It is best to plant the globe trumpet tree in a slightly moist, permeable and nutrient-rich substrate. The tree, which comes from the USA, does not tolerate waterlogging at all, nor does it tolerate soil that is too dry.
When is the best time to plant the globe trumpet tree?
The frost-sensitive globe trumpet tree should, if possible, only be planted in mild locations and only in late spring, as soon as the risk of late frost is no longer present.
What planting distance should be maintained from other plants?
Since the tree can grow up to six meters wide when it is old, it is best to plant it as a solitary plant with the appropriate distance from other plants.
What needs to be taken into account when planting the ball trumpet tree?
It is better not to plant the globe trumpet tree in very cold winter regions. Planting substrate is ideally improved with humus, coarse sand and clay. Freshly planted specimens must be watered thoroughly.
Can the ball trumpet tree also be cultivated in a pot?
Keeping the globe trumpet tree in a pot is recommended, especially in the first ten years, as this is the only way to ensure frost-free overwintering. However, older trees can easily survive the cold season in mild areas if they are hardened accordingly.
Can the ball trumpet tree also be transplanted?
Replanting the ball trumpet tree is usually possible without any problems after it has stood for two to three years. In this case, however, pruning should always be done at the same time to compensate for the inevitable loss of roots.
When does the ball trumpet tree bloom?
The ball trumpet tree usually blooms between June and July.
What is the best way to propagate the globe trumpet tree?
Normal trumpet trees can be propagated using root and shoot cuttings as well as seeds; the ball trumpet tree can only be propagated through grafting.
Tip
Unfortunately, the globe trumpet tree is very susceptible to verticillium wilt, a dreaded fungal disease. Since there is currently no effective antidote, only transplanting and vigorous pruning of affected parts of the plant will help.
