Trumpet tree origin

Trumpet trees (Catalpa bignonioides), are evergreen trees in the Bignoniaceae family. They originate from North America and were only introduced to Europe in the 19th century and quickly established themselves as ornamental plants. Today, trumpet trees are popular in many parts of the world and are often planted in parks and gardens. Trumpet trees are known for their long, drooping flowers, which appear in bright white, yellow or orange in early summer and are shaped like trumpets. The leaves are broad and heart-shaped and green in color. Trumpet trees grow quickly and can reach heights of up to 30 m. They are very adaptable and can thrive in almost any climate as long as they get enough sunlight and water. They are particularly good as shade providers, making them ideal for the garden. Trumpet trees are valuable plants that are not only beautiful to look at, but also have many positive properties. They are very adaptable and therefore well suited to the garden, and their long, drooping flowers are a real eye-catcher.

Trumpet tree care and location

The location for planting trumpet trees should be sunny to partially shaded and sheltered from the wind. They are best planted in moist, well-drained soil and need plenty of water and sunlight. However, they can also survive in dry soil by shedding their leaves and going into a kind of hibernation. Trumpet trees grow quickly and need plenty of space.

Pruning trumpet trees

Trumpet trees are robust and do not normally require any special care. The perfect time to prune is on a frost-free day in January or February before budding begins. In young trees, the main shoot should not be shortened or the side branches cut back. However, light shaping pruning is possible. When pruning trumpet trees, dead branches should be removed to keep the tree healthy. In older trees, it is also important to remove branches that cross each other, grow too close together, or grow into the interior of the crown. Branches that are too long should be shortened by a third or a maximum of half by making the cut 0,5 to 1 cm above a pair of buds or bud triplet. The cut should be chosen so that a side shoot branches off immediately below it (so-called diversion), otherwise broom-like shoots can form.

Watering the trumpet tree

Climate change is leading to hotter temperatures and longer dry periods in our regions, which has an impact on the environment and especially on the trees. Depending on the location and climatic conditions, it may be necessary to water the trees more frequently than in the past. Trumpet trees should be watered regularly, especially during longer dry periods. When watering with a garden hose, a lot of water is lost through runoff or evaporation.

A more efficient way of irrigation is to use tree bath watering bags. Water is released drop by drop to the trees over several hours through two holes in the lower area. This ensures that moisture does not evaporate above or seep into the deep soil to be absorbed by the roots. Another advantage of the watering bags is that the continuous watering prevents the risk of root rot.
Attaching and filling the water bags is easy and self-explanatory. The bag is placed around the tree trunk like a jacket and closed with a zip. In the next step, you fill the bag with enough water so that after further alignment there are no more wrinkles in the lower area and then let it fill up. One watering bag is enough to provide young trees with sufficient water. For existing trees with a larger trunk diameter, two to three watering bags can be connected to each other to provide them with sufficient water.

Fertilize trumpet trees?

In spring the Fertilize with mature compost and horn shavings is recommended to provide the trumpet tree with nutrients. Trumpet trees are susceptible to pests such as aphids and butterfly caterpillars, but these can easily be treated with biological pesticides.
