Catalpa planting in open ground

Since Catalpa belongs to the decorative type of trees, this means that a special approach is required in the issue of cultivation. The basics of planting are the same as for most plants. It is necessary to correctly select the right, good soil for this tree, to plant. By the appearance of shoots, it is already necessary to carry out regular fixed watering, it is necessary for young shoots.

The use of various top dressings and fertilizers is not forbidden, however, it is necessary to ensure that there is not too much phosphorus in their composition.

All seedlings are divided into 2 types, annual and biennial. Moreover, regardless of their type, landing and care are virtually the same. Planting must be done directly in the spring, it can also be done in the fall, but only after the process of leaf fall.

Landing requires a site that is well sanctified by a natural light source, i.e. the sun. In addition, it must be reliably protected from the wind. This is due to the fact that Catalpa is by its nature a fragile plant, especially at the stage of formation it is very easy to damage.

When planting more than one tree, or close to other plants, it is necessary to maintain a distance between them of at least 4 m. This is explained by the love of the seedling to the open space, and besides, when it grows, it will spread quite widely. The root system also does not completely go down, but is widely stretched along the soil.

Formation of the landing pit should begin with ensuring the necessary depth of at least 100 cm, while its width should be at least 70 cm. Then you need to prepare a special mixture. It consists of humus, sand, peat, leafy land. All this must be combined with wood ash, just add about 50 g of phosphate rock. The resulting mixture must be placed in an already prepared hole.

However, before this, at the very bottom, it is necessary to make the so-called drainage layer, its thickness varies from 12 cm to 15 cm, but in no case should it be less than 12 cm.

Drainage is crushed stone, or pre-broken brick into small fragments. After the drainage layer is ready, the pit is filled with soil mixture. And only after that the planting of the root system of the plant begins. Then the ground is slightly crushed, compacted. Upon completion of this operation, it is necessary to water the seedling.

Immediately after watering, it is necessary to mulch the soil, peat is excellent for this role.

Catalpa Care in the Garden

Catalpa is known for its love of moisture.

When growing this beautiful tree in the garden, it is necessary to water at least 1 time per week. It is worth remembering that at least 2 buckets of water are needed per plant.

There are exceptions to the frequency of watering. These include cloudy, rainy weather. If rainfall prevails in the region, watering can be reduced to 3 times per month. If, on the contrary, the region is arid, then the number of watering sessions, on the contrary, is increased, up to 2 times a week. After each watering, it is necessary to thoroughly loosen the soil around the trunk, while not forgetting to remove the emerging weed grass.

The tree responds adequately to fertilizing and various fertilizers, even with some “enthusiasm”. The addition of additional nutrients to the soil also needs to be done regularly. It is necessary to create a schedule for fertilizer application, while each session should be fixed, and there should not be too much time between them.

For example, in autumn, a plant needs top dressing with a high content of potassium and phosphorus. At the same time, fertilizers containing phosphorus should be avoided during this period.

To give the plant the most aesthetic and beautiful appearance, it is necessary to trim it regularly. Spring is perfect for this business, since at this time the buds had not yet had time to fully form and swell. Pruning involves the removal of frost-bitten branches, which are also dry, sick, and damaged (broken).

Abnormally growing branches are also recommended to be removed, as they spoil the general appearance of the plant. It is in the spring that the crown is molded, giving it the necessary beautiful shape.

Young seedlings not only require protection from the wind, but also shelters in the winter, even frost-resistant varieties. As they grow older, winter-hardy species do not need this.

Catalpa breeding

Planting seeds for seedlings is recommended to be done in late February, or in early March. Before this, the seeds of the plant are thoroughly soaked for 12 hours in water. If planting is expected in the fall, then the seeds should not be soaked in water.

Technology of seed germination:

  • In pre-prepared containers with the necessary soil, they make peculiar grooves into which seeds will be distributed.
  • Then the seeds are covered with soil, after which they are watered, but not abundantly. If you overdo it, you can destroy them.
  • After watering, the containers are closed with plastic wrap, or covered with glass in order to create a greenhouse effect. Containers are placed in a room where the air temperature is at +22 ° C. Every day they remove the shelter for 10 minutes, so that the plant is slightly aired.
  • In the room with seedlings, you need to provide enough light, but you should make sure that direct UV rays do not get on the seedlings, this will badly affect the sprouts.
  • They also monitor watering, regularly and dosed produce it.

Landing in open ground becomes possible only in mid-May.

In addition to seeds, this plant can also be propagated by cuttings. Cuttings are harvested for these purposes around the month of August. They are cut off at least 8 cm, always with mature, living kidneys. Cuttings are immediately planted in a substrate consisting of sand and peat. With the help of plastic bottles they create a greenhouse effect. Care for cuttings is exactly the same as for seedlings. Regular watering, daily need to remove the bottle for 10 minutes, for ventilation of the sprouts. Landing in open ground is made, as with seedlings, closer to the end of May.

Catalpa pests and diseases

Despite the fact that the plant is mostly decorative, nevertheless it has a fairly strong immunity, which allows it not to be exposed to most common diseases. However, the strength of immunity directly rests on the correct care of the plant. If you neglect any nuances, then even the mildest disease can easily hit this beautiful tree. And as often happens, they may not be treated and the only way out is to remove the plant.

Such dangerous defeats include spaniard flies. When they appear, or if their presence is suspected, the plant must be treated as soon as possible with special agents against pests. Such products are freely sold in garden shops.

A more dangerous problem is the cattail. They lay larvae in the bark of the tree, which in turn significantly damage it. As a result, the plant begins to rapidly fade. As such, there is no solution to this problem; damage to the larvae for the plant means death. However, it is still possible to protect the tree, for this it is necessary to carry out certain preventive measures, regularly treat with insecticides.

No less dangerous than pests for Catalpa is the disease of verticillus withering. Signs of this ailment are yellowed leaves, falling off. Only the initial stage of the disease is treated, for this, special drugs are used, such as Fundazole. When the disease has already developed enough, it is impossible to cure the plant, only its complete removal will help.

Also, the tree can be affected by powdery mildew.
