The trumpet tree (Catalpa bignonioides) originally comes from the warm and sunny southeast of the USA, where it is cultivated as an ornamental tree in many gardens and parks, primarily because of its large leaves and funnel-shaped, white flowers. The summer-green deciduous tree is also enjoying growing popularity here.
How do I plant a trumpet tree correctly?
To plant a trumpet tree, choose a sunny, warm and wind-protected location with sandy, nutrient-rich soil. The ideal planting time is late spring or early fall. Dig a planting hole twice the size of the root ball and mix the excavated material with compost and horn shavings. Make sure to water adequately after planting.
Which location does the trumpet tree prefer?
A sunny, warm and wind-protected location is ideal. The trumpet tree is very heat-resistant, but quite sensitive to frost.
In which substrate should you place the trumpet tree?
The trumpet tree feels most comfortable in sandy, but nutrient-rich and slightly moist soil. However, excessive dryness - especially in hot weather - and waterlogging should be avoided.
Can you also cultivate the trumpet tree in a pot?
In principle, you can also keep the trumpet tree in a sufficiently large and deep planter, but in this case the tree needs very careful care.
When is the best time to plant the trumpet tree?
Well-rooted container goods can be planted throughout the growing season, but late spring or early fall is best for planting out in the garden.
What planting distance should you choose for the trumpet tree?
Since the trumpet tree can grow up to 12 meters high and 10 meters wide in our latitudes - in its homeland it even reaches up to 18 meters - you should give the young plant enough space to grow. Catalpa feels most comfortable as a solitaire.
How should you best plant the trumpet tree?
Before planting, you should place the root ball in a bucket of water and let the roots soak up. Meanwhile, dig a planting hole that is twice the size of the root ball. Mix the excavated material with plenty of compost (€12.00 on Amazon) and horn shavings and ensure good drainage. After planting, ensure there is sufficient water supply.
When does the trumpet tree bloom?
The common trumpet tree shows its attractive flowers in the months of June and July.
How can the trumpet tree be propagated?
Propagation is easily possible via cuttings and seeds. Older trumpet trees also develop subsidence.
Can you transplant the trumpet tree?
As long as the trumpet tree is not older than four to five years, it should be possible to transplant it without major problems. However, older trees are difficult to move.
Tip
If you don't have that much space in the garden but still want a trumpet tree, we recommend the much smaller ball trumpet tree 'Nana'.
