Trumpet tree captivates as a grandiose structural artist in the creative garden
The trumpet tree brings creative garden design as a stylish piece of jewelry. Large, heart-shaped leaves, fragrant trumpet flowers, up to 35 cm long pods in autumn and a round shaped crown characterize the ornamental tree. The cultivation of a catalpa is easier by hand, as the striking silhouette suggests. The following answers to frequently asked questions show you how to do it right.
Plant the trumpet tree properly
In early spring, in the sunny spot, you can pick a plant pit that is twice the volume of the root ball. Put the excavation in a wheelbarrow to mix in compost and horn shavings. Meanwhile, the still potted root ball is soaked in a bucket of water until no more air bubbles rise. Before potting and planting the young trumpet tree, beat a support pile into the planting pit. When choosing the planting depth, please make sure that there is only just below the garden soil at the end of the soil ball. Join trunk and support pile with a wide binding material that does not cut into the young bark. On the day of planting and during the following weeks, water regularly and abundantly without causing waterlogging.

care Tips
If you pay attention to the following care program, the trumpet tree fulfills all the expectations put into it:
The strains of the Central European winter, a young Catalpa in the first years of life not much oppose. Protect therefore the wood with a thick layer of leaves on the tree disk, fixed with Nadelreisig. The young branches receive a shell of breathable material, such as garden fleece or jute bands.

Which location is suitable?
Choose a sunny, warm and sheltered location. These framework conditions are of particular relevance for a young trumpet tree, as it only has the robust hardiness of an adult specimen over the years. In addition, the branches break, when again and again violent wind tugs at them. In addition to the temperature and light conditions, the spatial capacity plays an important role in the choice of location. Since the common trumpet tree (Catalpa bignonioides) can reach a height of 12-15 meters, the distance to buildings, the neighbor and other plants must not be too tight.

The right planting distance
Because of its stature height, the trumpet tree, including its hybrids, is assigned to the trees of the third order. As a safe distance to buildings, we therefore recommend the following planting distances:
The planting distance to the neighbor in Germany is regulated by law at the state level. Therefore, ask the competent regulatory or construction office for the prescribed distance and can be this statement for safety's sake in writing.

Which soil does the plant need?
In fresh, damp to moderately dry soil, the heart roots find suitable conditions. Rich in nutrients, the soil should also be profound and humic. Avoid a location with the risk of waterlogging. While the trumpet tree comes to terms with brief droughts, persistence puts an end to his life in no time at all.

What is the best planting time?
In view of the frost sensitivity of young trumpet trees, we recommend a spring planting. This makes even more sense than that the tree drives out very late anyway. If a catalpa has all summer and fall to root in the ground, he is well prepared for the first winter. The typical autumn time for native trees is too short for a sufficient rooting before winter.

When is flowering time?
From June to July, the trumpet tree makes its own flower dress. Look forward to white, trumpet-shaped flowers with purplish or pink stipe on up to 15 cm long panicles. Do not wipe out the withered flowers, as this produces decorative pods of 30-35 cm in length, which linger on the tree well into winter.

Cut the trumpet tree correctly
Its symmetrical crown develops a trumpet tree in its own right. If enough space is available, you can let the noble wood in growth free. Only an annual Auslichten is in early spring on the care plan, so that the crown does not verkahlen from the inside. Try a cutback to limit size and volume, do it right:
Dead branches cut off at the base on this occasion. Please make sure that the stem bark is not injured. The same applies to inward and rubbing branches.

Pour trumpet tree
The trumpet tree prefers a constantly slightly moist soil, which dries in the meantime. Please adjust the amount of water for the progress of the growth. As long as leaves do not form on the branches, the tree gets only a little water. Over the large Herzblätter evaporates during the summer plenty of moisture, so that the casting requirement increases disproportionately. Check every few days with a thumb sample to see if the surface of the earth has dried to a depth of 3-5 cm. Slowly add the water to the root disk to avoid puddling as a symptom of imminent waterlogging.

Fertilize the trumpet tree properly
In the humus rich, nutrient-rich soil, the demand for fertilizers is at a low level. Organic fertilization with compost and horn shavings in March / April is sufficient here. Please do not expose a trumpet tree to the concentrated charge of a mineral complex fertilizer. Cheaper on vitality, flowering and leaf beauty are slowly decomposing organic materials. In addition to compost and horn shavings, bark humus, Lauberde, guanogranules and horse manure come into question.

Diseases
The furious heart leaves provide the ubiquitous fungus spores of mildew with a welcome spread surface. This is especially true during damp, warm summer weather. Spreading on the beautiful foliage a floury-gray patina, your immediate intervention is required. Cut off infected leaves to dispose of them in the household waste. Then sprinkle the tops and bottoms of the remaining foliage repeatedly with a 9: 1 mix of water and fresh milk.

overwinter
Only in advanced age does a trumpet tree have a robust frost hardiness. For the first 5 years we recommend the following arrangements for a healthy wintering:
Already in autumn you can influence an undamaged winter time. In August and September, spray over the tree disc repeatedly with comfrey. It contains plenty of potassium. This nutrient strengthens the cell walls and lowers the freezing point of the cell's juice.

Multiply trumpet tree
To breed more specimens of the trumpet tree, the following propagation methods are available:
By contrast, the multiplication of a refined Nana ball trumpet tree belongs to the hands of an experienced gardener.

Is the trumpet tree poisonous?
The plant sap in shoots and leaves can trigger allergies on contact with the skin, which is of course only the case with very sensitive people. In contrast, the long pod fruits in autumn are to be treated with caution. The seeds in them can cause significant symptoms of intoxication, such as nausea, vomiting and convulsions. For consumption, the cigar-like capsule fruits of a trumpet tree are therefore not suitable. In the family garden we therefore recommend the cultivation of the ball-trumpet tree of the variety 'Nana'. Since this does not bloom, no poisonous fruits can form on this.

Trumpet tree does not bloom
Until the first flower, a trumpet tree takes at least 8 years time. Depending on the site conditions, it can take up to 15 years to land the pretty flower spikes for the first time. If an older tree does not flower, it lacks nutrients or the site gets too little sunlight.

Yellow leaves
If the leaves of individual branches of the branches become yellow in color, while the remaining leaves remain green, the Verticillium wilt has struck. The wilting fungus infects the trumpet tree from the ground and blocks the pathways. The water and nutrient supply is reduced and eventually comes to a standstill. Effective control methods have so far not been developed. Cut the tree back to healthy wood and put all the framework conditions to the test. With a little luck, the stressed Catalpa will recover.
