Preferably fertilize the trumpet tree with compost
The trumpet tree (Catalpa bignonioides - not to be confused with the angel trumpet!) Is considered quite easy to maintain.In fact, the exotically beautiful exotic grows quite fast to an imposing size, provided that he feels comfortable at his location and you stick to the main care rules. Above all, a protected, warm location and a humus-nutrient-rich soil are important. Although Catalpa is considered heavy, you should not be too wasteful, especially with artificial fertilizers.
Suitable fertilizers for trumpet tree
The trumpet tree benefits especially from organic fertilizers, especially from mature compost - which you can apply especially in early spring and autumn - horn chips and a well-balanced, mineral-rich garden fertilizer. However, before you provide your trumpet tree with such resources, a soil analysis is often useful. Although this costs a bit, but you get specific information on what nutrients are missing and how you should fertilize best.
Why an overly nitrogenous fertilization is counterproductive
This is especially helpful in terms of an overly nitrogenous fertilization, because such stimulates the growth and the leaf outflow immensely, but also has many disadvantages. Too much nitrogen leads to the fact that the trumpet tree prefers to put its energy into instinctual growth and that it leaves out the flower. In addition, the fast-awake shoots often do not come to maturity in time for the winter, so they eventually threaten to freeze to frost. In particular, cheap fertilizers contain too much nitrogen, so a close look at the label (and thus on the contents) is well worth it.
Mainly fertilize young trees and tub specimens
Older and gardened trumpet trees are usually able to provide themselves with sufficient nutrients. Here it should be enough to supply the tree with a little compost in the spring. Younger and not so well-established specimens should be regularly fertilized - they could, especially if they have just been planted freshly, not yet develop sufficient root material for self-sufficiency and are therefore still dependent on an external supply. The same applies to tub specimens, which can not provide themselves with water and nutrients.
Tips
To help young trumpet trees, you can already enrich the soil with organic fertilizers when planted. Mix the excavation with compost and / or horn shavings for this purpose.
