The trumpet tree is very late
Trumpet tree (Catalpa) - budding takes place very late
The catalpa bignonioides (Catalpa bignonioides) becomes an imposing appearance as it grows older: the spreading, several-meter-wide crown contains heart-shaped leaves of up to 20 centimeters in length, which form a fascinating combination, especially during flowering, when combined with the orchid-like flowers , However, you need a lot of patience until you can enjoy this sight. The trumpet tree naturally expels very late in the year.
Trumpet tree is also jokingly called "official tree"
While in the garden everything is already green and blooming and the gardener enjoys the waking spring splendor, the trumpet tree is still freezing around. Many times the catalpa, which was often dubbed the "Official Tree" due to its very late sprouting, was declared frozen in the cold season. You can rest assured, though, if your trumpet tree does not have any leaves in April, even beginning to mid-May: that's normal, they're still growing! However, the deciduous deciduous tree, originally from the southeastern United States, drops the leaves comparatively early - as officials say: come late and leave early.
Encourage foliage emergence through targeted fertilization
However, they can help the leaves by means of targeted fertilizer on the jumps. In particular, fertilization with nitrogen-enriched fertilizers in early spring not only promotes growth, but also the formation of the leaves. However, too much nitrogen can cause the flower to suffer later or even to fail altogether. Instead, you can indulge Catalpa with a generous helping of compost, which is distributed in the area of the tree slice in March / April and carefully incorporated. But beware: The roots of the trumpet tree are mostly close to the earth's surface!
Protect the crown from late frost in the spring
In our latitudes, frost occurring late in the spring, especially at night, can be problematic not only for the flower buds but also for the leaf shoots. With a little bit of bad luck, the plants freeze for this in the early spring months, so that frost protection appears necessary. For this you can cover the crown of the tree with an antifreeze foil or a gardening fleece and thus protect the buds from freezing.
Tips
You should be particularly careful with young trumpet trees, because they are even more sensitive to frosty temperatures than older specimens.
