Catalpa is a fast growing ornamental tree. Garden decoration is his vocation. In the spring or early summer, the catalpa attracts attention with a beautiful and fragrant flowering, then the trees are covered with large dark green heart-shaped leaves, and long pods with seeds appear in place of the flowers (for these pods the people call the catalpa "pasta"). In addition, the catalpa has a compact rounded crown and a neat trunk. The heat-loving southerner - catalpa, the landing and care of which is discussed below, can safely grow in the harsh climate of Central Russia, if certain conditions are created for it. If at home the catalpa grows up to 30 m in height, then, for example, in the Moscow region it is known as a small park tree up to 5 - 10 m high.
Location and soil for planting
For planting seedlings need to choose a sunny and protected from cold winds place. These conditions must be observed, especially in regions with cold winters. Otherwise, the freezing of young growth is inevitable.
The soil prefers neutral or slightly acidic, fertile and breathable. It does not tolerate close occurrence of groundwater and spring flooding. When planting in the planting pit is recommended to make a mixture of humus, rotted leaves, sand and peat. It is also useful to add superphosphate and wood ash.
The size of the planting pit depends on the size of the seedling. An annual seedling grown from seed can be planted in a well of 30–50 cm deep, and for larger perennial seedlings a hole 100–120 cm deep will be needed.
After planting, the soil is well watered and mulch pristvolny circle.
On fertile soils, with sufficient illumination, the catalpa annually gives a good growth and pleases with abundant flowering already for 4–5 years. Tree care is simple and easy: during the growing season, the plant needs moderate watering and rare dressings, in the spring formative and sanitary pruning is important, and in the fall, measures are needed to increase the winter resistance of young seedlings (mulching, sheltering with a sackcloth).
Catalpa responds well to fertilization. For the season it is enough to hold two dressings:
- at the beginning of the active growth of slurry,
- in the period of mass flowering complex mineral fertilizers.
Feeding is carried out directly after abundant watering.
Spring pruning is necessary to preserve the decorativeness of the crown. Remove dry and broken branches and blackened tips of young shoots affected by frost. Catalpa safely transfers pruning and lends itself well to shaping.
Features of cultivation in the Moscow region
In central Russia, two types of catalpa are acclimatized: bignonic and gorgeous. They show sufficient frost resistance. If you get a seedling from an already adapted plant (collect the seeds from the pods in a local park), then you should not worry about such a plant.
In the first years after planting, catalpa seedlings need protection with covering materials (agrofibre or spruce branches) in case of a snowless harsh winter. For the best growth in the Moscow region are required dressings. In arid regions, particular attention should be paid to irrigation.
For suburban areas of Central Russia, the catalpa remains a rare wonder, although it is quite realistic to grow this exotic beauty.
In seed reproduction, ripe pods are harvested in the fall and seeds are removed (if the seeds have ripened, then it is not difficult). Sowing is carried out in early February, pre-soaking the seeds for the night in warm water. The composition of the substrate should be universal: humus, sand, garden soil and peat. Seeds are evenly distributed over the leveled surface and slightly sprinkled with soil. Crops should be rare for the full development of seedlings. The boxes are placed on diffused sunlight and covered with glass before germination. For seed germination requires regular watering and a temperature in the range of 20 ± 5 ° C. During the month, appears pretty friendly shoots. In April, if the seedling is cramped in boxes, you can pick a pick into separate pots. In open ground planted in late May, after the threat of return frost.
In central Russia, the usual, bignonemic, hybrid, spherical catalpa can grow. In the Moscow region, its most frost-resistant species, such as the magnificent, beautiful, non-flowering standard form of the bignyoniform catalpa Nana, take root.
The most frost-resistant of them - beautiful catalpa. It can withstand temperatures as low as -40 ° C. In some parks there are trees older than 50 years. In the 1930-1950s, the well-known breeder NK Vehov, a very breeder of the frost resistance of catalpa, was very advanced.
Bignonia catalpa in the suburbs often reaches only 4 meters. But if you grow seeds and seedlings in the same region, do the right pruning, shelter, feed, then the tree will delight everyone with beauty and size.
Use in garden compositions
It can be an ornament to any garden composition. Due to the short stature of catalpa in this region, it is rarely used here as a separate tree. More often, catalpa is made part of the overall composition, combined with deciduous magnolias and oak.
Often they are framed by paths, they well strengthen the soil on the banks of rivers and lakes, small fresh water bodies.
How to choose seedlings when buying
Catalpa can be planted as seeds, cuttings, layering. When choosing seedlings to pay attention, first of all, on winter hardiness of a plant. It depends on the conditions in which the cutting was grown. Seedlings grown in the same region as the landing site in the open ground, more adapted.
The problem is not only in low temperatures in the winter, but also in the short summer. If temperature limits and other indicators were different, then the seedling is difficult to adapt to the new vegetative period. Often, adaptation ends in death, since the needs of the plant development processes do not coincide with the necessary conditions. For transplantation, 1-2-year-old saplings with an open wide root system are best suited. They are better acclimatized with a clod of earth on well-fertilized soil, with a well-designed drainage system.
The choice of location: soil and lighting
So that the tree does not give a large increase in the vegetative period, the soil must be poor, with pH7 acidity. Too quickly formed and a large growth of the tree is subject to more frosting due to the fact that he did not have time to woody.
It is very important to choose the right place for landing. Light and heat-loving catalpa is better suited sunny, closed from the cold winds place.
They called him "katoba", however, a little later it was renamed Catalpa by the Italian scientist and botanist Skopoli. It was he who first studied and described the catalpa, opening this exotic plant to the world.
Bignonium genus combines from 10 to 38 types of catalps. Some of them are cultivated in the southern strip of Russia, Belarus and Ukraine, the rest, you can only see in the wild.
Catalpa is an unpretentious and fairly easy-to-care plant, so if you want to decorate your garden area, giving it beauty and unusualness, then it is exactly what you need.
Catalpa species and varieties

Blooms catalpa in June. Purple or pink flowers with an orange pharynx are collected in large, friable, pleasant-smelling brushes. After flowering, long and thin fruits in the form of pods are formed.
Catalpa planting and care in the Moscow region
Planting a catalpa and caring for it is not much different from any other ornamental tree. Catalpa seedlings can be purchased in the nursery or grown from seeds on their own. It is necessary to plant a young tree in the garden plot in the spring, before the sap flow begins or in the fall, when the trees lose foliage.
For catalpa landing, it is necessary to find a site with good illumination, which will be closed from winds and drafts. This is necessary because the tree has a very fragile leaf cover, which is easily traumatized by gusts of wind and strong drafts.
It will also be a plus if the site groundwater will be as deep as possible under the ground. Catalpa loves space, so between a young plant and other trees it is necessary to observe a distance of at least 5 meters.
Landing catalpa in spring
The pit should be 100 centimeters deep and 70 centimeters wide. At the bottom of the pit should be laid drainage in the form of rubble or broken brick. The thickness of the drainage layer should be about 15 centimeters.
When the drainage is laid, soil is poured on it, by volume a little more than half of the pit. Then a tree is placed in the substrate, having previously straightened the roots. The remaining void is filled with soil and slightly compacted.
After planting is completed, the tree is abundantly watered. It is necessary to ensure that after absorption of moisture, the root neck is lowered to the level of the soil surface. Also pristvolny circle should be mulched peat or straw.
Campsis is also a member of the Bignonium family. Grown when planting and care in the open field without much hassle, if you follow the rules of agricultural engineering. All the necessary recommendations for the cultivation and care of this vine are available in this article.
Catalpa loves water, so watering should be systematic and carried out once a week. In the dry period, it is increased to two times. If the tree does not have enough moisture, its foliage will lose elasticity and sag. For watering an adult tree, you must use 20 liters at a time.
If summer is cool and rainy, watering should be reduced to twice a month. The same amount of watering necessary and zamulchirovannoy catalpe. After adding water under the tree or after rains, the ground around the trunk should be loosened, removing weeds in parallel. With prolonged drought, the frequency of watering should be increased.
The soil for catalpa should consist of humus, sheet soil, sand and peat in a ratio of 3: 2: 2: 1. 7 kilograms of ash and 50 grams of phosphate rock should be added to this substrate.
Land for planting should have an acidity of not more than 7.5.
Transplanted catalpa in two cases: if an adult tree has grown and there is little space for it, or if it is necessary to transplant a young plant from a pot to an open ground. Tree transplantation can be carried out both in the spring before the start of sap flow, and autumn, when the tree drops foliage.
It is better to transplant a tree together with a lump of earth, with which an adult tree or a young sapling grew before. The planting pit is dug up the same depth as when planting a catalpa, the composition of the soil mixture also does not change. After transplantation, it is necessary to tamp the soil and water the plant abundantly.
Fertilize the tree should be systematically. For this purpose, a solution of rotted manure diluted with water in a ratio of 1:10 should be added to the ground where the catalpa grows. An adult tree needs 6 liters of such top dressing, and a young seedling needs from 2 to 3 liters.
Top dressing is carried out twice a season. In the spring, nitroammofoska is applied to the soil under the tree, and in the fall - phosphate and potash fertilizers, since at this time the plant needs nitrogen.
Kidney catalpa appear in late March - mid-April. It all depends on what band of tree in Russia grows. The flowering period begins in mid-June and lasts about a month.
Catalpa flowers resemble exotic and beautiful small orchids that smell like apple flowers. Лепестки у цветов имеют волнистые края и белый либо кремовый оттенок с желтыми полосками и пурпурным крапом в зеве. Размер цветков достигает до 7 сантиметров. Они собраны в крупные и длинные соцветия, напоминающие «свечи» каштанов.
Катальпа обрезка и формирование
Обрезку катальпы проводят весной, до того момента когда набухают почки. During pruning, only injured, dry, frozen or damaged branches or pests are removed.
Usually, a tree is formed by creating a stem with a height from 120 to 200 centimeters; the tree above it will branch out, forming a sprawling, low crown consisting of 5 skeletal branches.
After a certain period of time, if necessary, the skeletal branches are shortened, and the thickening stems are removed. As a result, a dense, beautiful rounded crown with light green leaf plates is formed.
Preparing catalps for winter
Catalpa does not tolerate cold. Especially their "fear" of young trees. For this reason, the tree should be prepared in advance for the winter. For this purpose, it is necessary to wrap the trunk with sacking, and cover the soil around the tree with a thick layer of dry foliage and cover with spruce leaves. Thus, it will be possible to avoid the freezing of the root system. With the onset of spring, when the frost is completely stopped, the tree is freed from shelter.
It is necessary to take into account the fact that as it grows and develops, the catalpa becomes more frost-resistant and better tolerates the winter. The most frost-resistant variety is catalpa ovoid, and the weakest, freezing almost to the ground - catalpa Aurea. However, this variety is able to fully grow over the summer.
Catalpa of seeds at home
When growing catalps from seeds, they should first be stratified. It is necessary to sow seeds in the end of February, the beginning of March. Before sowing, seeds should be soaked in warm water for 12 hours. You can also sow them in the fall, but in this case, you do not need to soak the seeds.
In prepared soil, small grooves are made in which the seeds are laid out and powdered with a layer of substrate. The box with seedlings, covered with a layer of film and cleaned in a lighted, warm place. The temperature for good germination of seeds should be at least 25 °.
Crops must be protected from direct sunlight, systematically watered and ventilated. Saplings grown during the year can be planted in open ground when the threat of frost passes.
Catalpa breeding cuttings
When growing catalpa using cuttings, planting material should be harvested in July. The cuttings should have a length of 8 centimeters, they should also be from 2 to 4 buds. When preparing material for planting, you should choose an adult catalpa.
In order for the roots to appear on the cuttings, they must be planted in the ground, which will include peat and sand, then cover the box with the cuttings with a film and put it in a warm and bright place. Hoopoe for cuttings should be the same as for seedlings. When the cuttings rooted on them will appear young foliage. The landing of the finished young in the open ground can be made in mid-May.
Diseases and pests
Catalpa is resistant to both diseases and pests. But while the tree is young and weak, it can attack Spanish fly. In order to destroy the pest, it is necessary to spray the young catalpa with the insecticide “Decis” or “Fastak”.
Also a young plant is threatened and horntailswhich settle on the trunk and resemble hornets in appearance. They bite through the bark and lay eggs there, and when the larvae hatch, they begin to feed on catalpa, as a result of which the eggs weaken and dry. An adult invasion of rogtail is not threatened. Spray an insecticide "Aktellik" to destroy this insect.
Catalpa can get sick verticillary wilt, which primarily affects the lower part of the crown, and then covers the entire leaf cover. When verticillosis leaves begin to turn yellow, fade and fall off. You can get rid of this disease of fungal ethology by irrigating with drugs such as “Maxim” and “Rovral”. Krona can be processed "Fundazol." For prevention the plant is sprayed with Previkur.
The exotic catalpa will become an ornament to any garden plot, bringing in the overall landscape composition, originality and aestheticism. And with proper care of the tree, it will be for a long time to please with its decorative and unusual delicate flowers with a pleasant apple flavor.
Types and types of catalpa
For the cultivation of catalpa in the suburbs should choose more frost-resistant varieties. The most suitable plant in this regard will be a magnificent catalpa.
For the southern regions, catalpas of bignoneiform and ovate are suitable. These trees can tolerate a cold snap of up to minus 25 ° C for a short duration; therefore, in the Moscow region, they are usually grown in containers. Try to purchase cuttings or seeds that have been acclimatized to life in this band, then they will feel much better than those that were brought from the south or from abroad.
The standard non-flowering form of the bignonic catalpa Nana, which is able to spend the winter without shelter, is well adapted to life in the Moscow region. In the first year of planting a tree covers the root system and the site of grafting. The increase in catalpa of this type is annually due to the growth of the crown, which is annually formed by pruning.
Location and soil
For catalpa landing you need to choose the right place. Suitable for a tree warm and sunny place that will be well protected from the cold northern winds. A tree or a bush may freeze in winter; it happens that in severe frosts, catalpa freezes to the ground.
Do not be afraid of this, for the current season, it is able to grow back to the height of one and a half meters. If your catalpa grows in a container, then for the winter it should be removed in the room. In this situation, the tree or shrub should be transplanted each year into a larger container. For catalpa, you need to find a place with fertile and light soil, good drainage, acidity is closer to neutral.
You can plant catalpa seeds, in this case, the freezing will be reduced to a minimum, but flowering occurs only in the fifth or seventh year after planting. For the landing, it is necessary to prepare a mixture of peat with humus, sand and leaf earth (1: 1: 1/2: 1). Mineral fertilizers, wood ash, dolomite flour are added to this mixture, everything is mixed.
The pit, which will be held landing, prepared for two weeks before this point. The top layer of earth can be added to the planting ground. The root system of the tree is not deep, but superficial and branched, so the pit is made wide and not very deep. If you plant several trees next to each other, then the distance between them should be at least three meters. Immediately after landing, the catalpa should be poured and the tree trunks should be mulched with peat.
Water catalpa should be once a week, about 18 liters of water are poured under each tree. Catalpa responds well to fertilization, during the feeding season, it is applied two or three times. Effective fertilizer will be slurry, for one tree 5 liters of this fertilizer is required.
The important point of catalpa care is pruning, which is carried out to form the crown of the tree and to get rid of sick and broken branches. In the spring, the tree wakes up later than many others, so do not rush to pruning. Frozen branches are pruned in early summer over the last surviving kidney, after which the sections are necessarily processed.
In winter, young catalpa seedlings should be sheltered; for this, sacking or mulch in the near-stem circle will do. The tree will become more mature, the less it will need shelter from the cold.
Step-by-step process of planting seedlings
Catalpa seedlings can be planted in spring or autumn in soil close to neutral. Planted in spring less prone to frosting. For such a picky tree, the pit needs to be prepared a couple of weeks before planting the seedling. It is being dug 0.8-1.2 m deep and wide, taking into account the fibrous shape and size of the root. In planting soil for catalpa you need to add humus, two parts of leafy ground, one part of peat and two parts of sand. If necessary, you can add a fertile layer of soil, 5-7 kg of wood ash and mineral fertilizers, such as phosphate, to the planting soil.
Pit well shed water. Pour the seedling right after planting, after having mulched the peat on the hole.
Leaving with knowledge
Growing catalpa in the Moscow region is associated with protection from wind and frost, irrigation and pest and weed control. Growing a catalpa in the west of the Moscow region requires cutting off frozen stalks.
After planting, the sapling grows slowly, vegetative activity at catalp in this region is delayed - they stand without leaves until May, they begin to bloom in the 5-7th year. When pruning frozen shoots, one should not be afraid of disturbing the formation of the crown - it recovers well and quickly after pruning.
Warming should be made in time and removed in time so as not to prevent the removal of moisture from the soil.
Watering seedlings should be regular - once a week 1-2 buckets. Watering an adult tree should be more abundant, pouring up to 18 liters at a time. Watering should also be systematic - once a week. At the same time it is necessary to prevent stagnant moisture, waterlogging. In cloudy weather, water when needed.
Catalpa seedlings need not be fed immediately after planting. After a year or two, at the beginning of the growing season, it is enough to feed them with slurry or with manure at the rate of 1 l: 20 l of water, pouring out 1 bucket of this solution under the seedling.
An adult tree should be fed 2-3 times during the growing season. At the beginning and in the second half of the growing season it is necessary to fertilize the tree with 5-6 liters of slurry in proportion to water 1:10 liters of water. Mineral fertilizers are applied once during the flowering period after watering.
When and how to bloom
Catalpa blooms for 3-4 weeks from mid-June. During this period, it is covered with abundant large inflorescences, exceeding in size the chestnut inflorescences, but very much resembling it. White and cream tubular flowers with purple and yellow stripes in the middle, with lace edges have a pleasant apple flavor.
How to deal with possible diseases and pests
Catalpa is not too susceptible to pests.
In cases of defeat Spanish fly The tree should be treated twice with “Decis”, “Kinmiks” or “Karbofos”.
In unbuttoned buds, Comstock worms may start. In this case, it is necessary to treat unblown buds with insecticides.
Fungus of the genus Verticillus can lead to drying and death of the plant, arises due to poor drainage of the soil and its too high density. Systematic soil loosening and good moisture permeability are the main preventive means from the appearance of fungi in the soil and catalpa contamination with them.
Despite the fastidiousness of the tree in the climatic conditions of the Moscow region, the catalpa will become an ornament to any composition, keep its eyes on her flowers, a thick crown will cover the sun, bizarre fruits will carry into the world of fairy tales, the cracked bark inspires tropics.
Catalpa is very easy to propagate by seed. It is necessary to collect the seeds in the autumn, when the pods mature well. Store seed for two years in a dry and always cool room. It is best to keep the seeds wrapped in paper or cloth.
- Before planting, closer to spring, the seeds should be soaked in warm water for 10 hours (minimum) - soaking greatly improves germination.
- Sowing seeds begin in late February-early March in the greenhouse, in the home greenhouse. You can sow the seeds in a container that will be tightened with a film or covered with glass.
Cutting of catalpa
Cutting of catalpa occurs in the summer, in the second half, you should prepare cuttings if you want to propagate the catalpa in a vegetative way. For cuttings cut healthy shoots up to 10 cm long with 3-4 healthy buds.
Cuttings root well in the nutrient soil. Before planting, the branches are placed for several hours in a growth stimulator to speed up root formation. Cuttings can be planted in boxes with nutrient soil and keep them in a warm room. The next spring, young plants will be ready for transplanting into open ground.
Sowing seeds can be carried out both in spring and autumn. In the open ground, seeds are sown in the furrows, sprinkling them a little earth. It is advisable to create a greenhouse effect so that the seeds together would sprout. To do this, it is better to sow the seeds in boxes that can be covered with glass. Glass should be removed regularly to moisten the seedlings and air them.
The temperature regime for seed germination should be about 20-25 degrees. It is necessary to moderately water the plantings and provide them with light. Grown seedlings, if you sow the seeds in autumn or winter, transplant them into the garden when the weather is stable and warm. As a rule, young plants are transplanted into the open ground at the end of May.
For planting seedlings need to prepare in advance the planting pits. Pits dig deep - up to 1 meter and wide - up to 70 cm in diameter. First of all, it is necessary to focus on the size of the root system of a tree. At the bottom of the landing pit should be poured 7 kg of wood ash, add 50 grams of phosphate rock and a bucket of humus mixed with sand and peat.
If you plant several trees, then the minimum distance between them should be 3 meters. It is optimal to leave a distance of about 5 meters between the seedlings.
When planting, the seedling is held vertically and dipped into a hole, tightly covered with earth and well spilled with water. Make sure the root neck of the seedling is level with the ground. The near-stem circles mulch immediately after planting. Peat, sawdust, lawn grass, straw will be used as mulch. The layer of mulch should be about 10 cm.
After planting, young trees in the first time in need of intensive watering. It is necessary to water plants abundantly once a week, spending no less than a bucket of water under each tree. The first few years, young trees shelter from the cold so that they do not freeze. On average, the plant grows by 1 meter per year, flowering occurs at 4-5 years of life.
Loosening the near-wellbore circles
Be sure to loosen the near-stem circles after each watering. During loosening, weeds should also be removed. It is necessary to loosen the ground deep enough, 30 cm, since the root system of catalpa is rod-like and it is very difficult to damage it. The plant will benefit from deep drainage and deep loosening.
Watering the trees is abundant every week. Under young plants it is enough to pour about 1-2 buckets of water. Under adult specimens, especially during the dry season, more than two buckets of water are poured. When watering, it is important to prevent stagnation of water, and therefore too zealous, and too much to pour the plant is not worth it.
At the beginning of the growing season, organic fertilizers should be applied under the catalpa. You can use a scum or slurry. Enough under the adult tree every spring to make about 5-7 liters of slurry.
With the beginning of flowering, the tree will gratefully accept mineral fertilizers. Usually, after irrigation, the plant is fed with any mineral composition.
For the winter, only young specimens are sheltered, who have not yet had time to woody. It is enough to wrap the trunks with a sacking cloth or any covering material, and cover the tree trunks with a thick layer of leaves.
With age, catalpa becomes more frost-resistant. Even if for severe frosts the shoots of the tree will freeze slightly, new branches will quickly grow in their place next spring.
In spring, the tree needs sanitary pruning, the purpose of which is to remove frozen and dry branches. Most often during the winter annual shoots freeze slightly. Catalpa perfectly tolerates pruning, and quickly gives an increase in green mass after it. A great many gardeners also form the crown of a tree with the help of forming pruning.
Using plants in garden design
The tree looks very original and highly decorative, and because of this it is widely used in landscape design. This view looks great both alone and in landscape compositions, next to other trees and shrubs in the garden.
The leaves of the catalpa are somewhat like the ears of an elephant, and the spherical, neatly shaped crown with an abundance of delicate inflorescences attracts attention. A catalpa-like plant is not so simple to find, and its simplicity in cultivation makes it a desirable inhabitant of any site or park.
- Dwarf varieties of this species, and sprawling tall forms will be used in garden design. Even in a small garden or in a modest area, you can find a place to plant a compact type of catalpa, for example, in a recreation area.
- Group plantings of this tree attract a lot of attention, for example, along the walking paths in the park or curbs.
- On the shore of an artificial reservoir, on the territory of the house adjoining site, the catalpa is simply an irreplaceable tree.
- Very often in the backyards, the variety “Nana”, with an unusual foliage of bright yellow color, is planted among gardeners.
- Catalpa looks great in the vicinity of the sprawling oaks in landscape gardening compositions.
- Excellent neighbors for this magnolia tree and a variety of ornamental shrubs.
Catalpa perfectly tolerates the pollution of the city, arid climate and winter cold. А в жаркий солнечный день дерево поделится своей прохладой и даст спасительную тень и свежесть.
