The bobovnik (laburnum) is a representative of the legume family, but it looks like a deciduous tree. Laburnum is home to the central part of Europe and the Mediterranean coast. The cultivated form of a tree is usually called garden bauber. It should be noted that this is not a kind of culture, but only its popular name.
The main difference between labourum and other decorative tree cultures are large clusters of yellow, pink, lilac and white shades assembled in hanging brushes. The length of the brush reaches up to 50 centimeters and during flowering they emit a very pleasant aroma, similar to Acacia.
If you properly care for the culture, it will delight the gardener with abundant flowering, the period of which will be at the end of May and lasts until the end of June. When the bovobnik blooms at the site of the inflorescences, fruits begin to form in the form of small pods with beans, thanks to which the tree can multiply by self-sowing.
Growing this amazing culture is quite simple, the main thing is to take into account all the advice of experienced gardeners, and an exotic bauber will surely appear on your site, which will delight you with its lush flowering, filling the air with an extraordinary scent.

They also have extraordinary decorative characteristics and intense pleasant aroma.
Barrage planting and care in the Moscow region
The rosemary is a culture for which the choice of landing site is not too critical, so it can be planted anywhere in the garden plot. For planting shrubs should choose a lighted place, because due to lack of light, the culture will no longer grow and develop, and either flowers will stop appearing on it or there will be very few of them, and the inflorescences will lose their brightness.
The cobblestone can grow on depleted limestone, therefore, it is often not necessary to add feedings during the growing season. For planting shrubs better to choose a place protected from drafts and wind. Since the root system of the tree does not tolerate the stagnation of moisture, the soil should be loose and well drained.
For planting bobovnika should choose several seedlings. Together, it will be easier for them to carry over the wintering, and their massive flowering will create a simply beautiful picture in the garden.
Young trees should be planted at the beginning of spring, when the snow melts and the earth warms up well. For planting should prepare in advance the planting hole, digging it to a depth of 50 centimeters. At its bottom it is necessary to pour a layer of expanded clay, fresh humus and lime. Then the bush should be placed in the pit along with the support to which it should be tied. This is necessary so that the young tree does not break under strong gusts of wind.
After it is placed in the landing pit, it is covered with garden soil, and the space around the trunk is mulched with a thick layer of a mixture of bark, sawdust, moss, straw and peat. When mulching is completed, the tree should be watered and lightly tamped up the ground.
The Crimson or Cercis is also a member of the Legumes 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 can be found in this article.
The soil for bobster
For planting you need to choose a nutrient soil with good drainage. It is best if the earth is alkaline. The acidic soil will need to be mixed with ash or lime, making it in the fall so that it can be planted in the spring.
Labourne does not like compacted soil and stagnant moisture, for this reason the earth should pass air well, and there should not be a crust after watering on the top layer of soil. This will help avoid mulching pristvolnogo circle.
Shrub transplantation is undesirable because it does not tolerate it very well. However, if it is required, it should be carried out very carefully so as not to damage the root system.
For this purpose, the coil must be dug together with the town commander and transferred to a new landing pit, having previously added to it compost, in order to ensure better rooting.
After transplantation, the tree must be watered and grunted near-stem circle. Transplantation should be carried out in the fall, after leaf fall.
Fertilizers for bobster
During the growing season, the tree should be fed, introducing trace elements into the soil. Organic is best for this purpose.
In the spring you need to carry out compost mulching. Also, several times per season the shrub can be fertilized with a solution of cow manure.
Flowering time occurs at the end of spring - the beginning of summer and lasts for a month. The inflorescences of bobovnik have the form of thick, large and long brushes, bright yellow, white, pink and lilac color with a persistent pleasant aroma.
Shrub blossoms profusely and attracts insects. In the place of the faded blossoms, small dark brown pods are tied with beans, which ripen to the beginning of autumn.
It is possible not to carry out the formative pruning of a tree, since it itself is gaining decorativeness, over time its branches will take on a beautiful, descending form.
In the spring, you can remove some of the frozen branches, but this should be done moderately so that the tree does not get sick. Pods with beans should be removed immediately after ripening in order to avoid self-seeding and improve the decorative qualities of the tree.
Since the branches of the tree have a sloping shape, in winter a large amount of snow sticks to them, and so that they do not break under its weight, they must be gently shaken from time to time.
Autumn leaves for the winter
If seedlings are purchased in the nursery, then they will not need additional shelter, since the young trees have already been acclimatized. If they were grown on their own, it is better to protect them, sheltering in the fall.
Since the young are very fragile, bend down to the ground carefully. After the branches are bent down, the shrub needs to be covered with spruce leaves and a thick layer of dry foliage. To prevent them from being blown away, they put lutrasil on top of the shelter and press it with stones.
Growing a bobovnika from seeds
Spreading bobovnik seed and vegetative way. When choosing a seed breeding method, it is better to choose freshly harvested seed material.
Some gardeners do not process seeds before sowing, but it is still better to stratify them. To do this, take the beans, mix them with wet soil or put in a wet gauze. Then they need to be wrapped in plastic and refrigerated for two weeks. After the expiration of the seeds can be sown.
For the seeding of seed material it is necessary to prepare a loose fertile soil. Sowing can be done in late autumn or spring, after the earth warms up. Seeds should be laid in open ground at a depth of 2 centimeters, leaving a distance between them of 15 centimeters.
Seedlings do not require special care and sprout on their own. You can also grow laburnum on the windowsill, sowing beans in February. For the growth of the young bobovniku will need light and moderate soil moisture. When young shrubs grow up, they should be moved together with the town commander to a plot in the garden where they will grow. Seed-grown trees begin to bloom only after five years.
Vegetative bovobnik reproduction in a vegetative way is considered more simple and successful. All varietal plants to preserve their unique characteristics are best propagated by this method.
Under vegetative propagation refers to the following methods presented:
- Cuttings - To obtain planting material in August, young branches should be cut off and rooted on the site in loose soil in partial shade. After planting the cuttings need to cover with plastic bottles before the formation of the root system. Watering future bobovnikov should be done carefully. In the first year of life, young shrubs need to cover for the winter.
- Graft - varietal cuttings should be grafted on species stocks. Vaccination site must be chosen close to the ground.
- Layering - for reproduction in this way it is necessary to bend the lower branch to the ground and sprinkle with soil. In the place where the roots should appear, on the bark you need to make several cuts. After about 30-35 days, the first roots will begin to appear, when they are old enough, the branch can be cut and planted in open ground.
Diseases and pests
Since bovovnik is a poisonous culture, pests bypass it. However, a disease such as powdery mildew. It begins to develop when the soil becomes too wet or prolonged rainy weather.
You can notice the appearance of powdery mildew on the trunk, which will begin to be covered with gray bloom. In the advanced stage of the disease affects the leaves. When the first signs of powdery mildew appear, sprays the spruce with the solution of the topsin M 500 SC fungicide, according to the package instructions.
Another problem exciting labourum owners is the lack of flowering. So, why does a leaf plant not bloom? The reasons for this may be many, the wrong place for planting, too dense soil, lack of nutrients, lack of winter shelter and freezing of branches, disease.
However, most often the lack of luxurious racemes, due to the fact that the tree lacks light. Transplanting it on a sunny plot can solve this problem once and for all.
The rosemary is a real miracle with extraordinary decorative characteristics. It will decorate the garden area regardless of where it will be planted. Most often, the leaf tree is planted next to the gazebos or along the arched structures, forming an unusual corridor, which turns into a real fabulous place during the flowering of trees, which will not take your eyes off.
It is easy to take care of labournum, therefore it is possible to “make friends” with a luxurious tree, even a novice gardener. Stick to all the above tips, and your garden is sure to decorate the luxurious bauber, which will delight you for a whole month with abundant flowering and pleasant aroma.
By the middle of May on racemes with flexible long stalks (20-50 cm), racemose dense buds bloom. Flowers exude a sweet, intoxicating scent, attracting insects to collect nectar. Blossoms very abundantly. Yellow flowers have a characteristic shape for the family of legumes, resembling moths. One wide petal, covered at the base with reddish strokes, is wrapped over the keeled lip, consisting of lower fused petals. Blossom blossoms from two weeks to 20 days.
After pollination by insects, brown beans covered with silky hair begin to ripen. Beans are up to 8 cm.
If you decide to have a branch in a garden, remember that it is poisonous. and it is in the fruits that the greatest amount of toxins is found. Planting of this plant is not recommended if there are small children in the family: even a couple of seeds eaten by them can be fatal.
Soil and watering
For planting choose a nutritious, well-drained soil. Preferably choose an alkaline soil, if the soil is acidic, it will require alkalization (you can add wood ash or a little lime, do it in the fall, in order to prepare the soil for spring). The bauber plant has a negative attitude towards soil compaction and stagnant water. It is better to mulch the soil surface with moss or peat so that a crust does not appear after watering.
Plant drought tolerates much better than excessive moisture. Therefore, it is necessary to water during periods of prolonged drought. Good watering is required during the flowering stage.
In the period of active growth, the tree requires micronutrients. Use organic fertilizer as a top dressing. In the spring, mulch the soil with compost. Several times a season, a mullein solution can be poured at the root.
Forming pruning bobovnik virtually no need. Even without human intervention, the falling shoots will take on a beautiful shape. You can remove some of the branches and frozen processes in the spring. Do this moderately so that labournum does not get sick. If possible, remove the beans after flowering, it will prevent self-seeding and increase the attractiveness of the tree.
Basically, the branches of a bovovnik of a sloping shape, therefore, in winter, a lot of snow accumulates on them. So that they do not break under such a weight, part of the snow mound should be shaken off.
If the weather is wet or the soil is excessively wetted, powdery mildew can strike a bauber at the trunk. On the branches and the trunk in this case, a grayish bloom. Finding such signs, improve the conditions of care and process the fungicide. Due to its toxicity, the Leaf is not affected by pests.
How to cover the leaves for the winter
Tender seedlings, whose origin is unknown, in frosty winter conditions are best protected, covered from autumn. Young trees are very flexible, they are gently bent to the ground, covered with spruce branches and a good layer of autumn leaves. From above, they cover with lutrasil and press them with stones so as not to be blown away by the wind.
Seedlings grown in local nurseries, already acclimatized immediately and do not require additional shelter even in the Moscow region.
How to propagate bobovnik vegetatively

Vegetative breeding methods are most successful. Varietal plants are recommended to propagate vegetatively in order to preserve their unique differences. You can use these methods:
- Cutting: in July-August, cut the young shoots, rooting produce in loose soil in partial shade. Cover the cuttings with a cap until the formation of roots, water carefully. These plants will need shelter for the winter in the first year of life.
- Inoculation: varietal cuttings need to be grafted on the species rootstock. Locate the vaccination site near the ground.
- Cuttings: bend the lower shoot to the ground and sprinkle with soil. В месте, где должны появится корешки, рекомендуют нанести на кору несколько порезов. Примерно через месяц появятся корни, побег можно срезать и высадить отдельно.

The plant itself can withstand temperatures as low as -25 ° C, but it can freeze the ends of the branches. The plant is common in southern Europe.
Decorative varieties are:
- Pendula - with long, drooping shoots
- Aurea - in spring, young foliage has a golden sheen, but gradually it acquires a rich green color,
- Quercifolia - oak leaflets of notched form,
- Automnale - presents blooms not only in spring but also in autumn.

Rosemary will be a real "golden" decoration of your garden. Plant individual trees solo in any part of the garden. Arbor, under a spreading crown, will be even more comfortable place to rest. Long lianoobraznye shoots can be directed along the arch, other supports, creating a magical cascade corridor.
A neighborhood with rhododendron, hawthorn, wisteria or skumpia is suitable for bovobnik. Juicy greens and bright inflorescences will stand out against the background of coniferous plants of dark green or bluish tones.
Three varieties of bobovnika
The area of distribution of the broom in nature is limited to the southern regions of Europe. Cultivation of bovobnik is possible on the territory of the Crimea and the Caucasus, the tree is also common in Central Asia.
The cascade of fragrant flowers makes the leaf tree a very attractive plant for decorating private gardens and parks. The plant is increasingly cultivated in garden plots. Broom is ideal for planting next to the purple wisteria, different types of honeysuckle and hops.
The genus Laburnum (the family of legumes) is small in number - only three types of trees are known in culture:
- Alpine filament at home (the southern regions of Europe) it grows up to 12 meters in height, the shape of the crown is bushy. It blossoms with drooping tassels of yellow flowers, which reach 45 cm. In cold winters, the upper shoots can freeze slightly, although this type of bauber has a high winter resistance.
Burler: planting and care (follow simple rules)
It should be noted that the cultivation of unpretentious culture is not particularly complex. When planting labourum is required to find a sunny place with permeable soil. With insufficient sunshine, flowering is delayed or does not occur at all.
Important! The plant does not withstand the stagnation of water at the roots, well developed on poor, calcareous soils without excessive introduction of organic matter.
When planting broom should provide protection from the wind. Plants in the garden are preferably planted in groups, because they tolerate wintering more easily and bloom more abundantly. The best time to plant a crop is early spring, immediately after the snow melts.
For planting laburnum seedlings should be prepared in advance pits. Fresh humus earth is added to the bottom of the pits with the addition of lime. A seedling is put in a hole, along with it they dig in a supporting trunk, to which they tie a young tree. Pristvolny circle mulch bark, peat, moss or a special film to preserve moisture.
After flowering, caring for a plant is reduced to the removal of withered brushes and timely watering.
Special care should be taken in the winter. If the branches are frozen, the flowering of the plant will not be as amazing and beautiful as in the photo. In the central and northern regions of Russia, the Leaf should be sheltered for the winter. In heavy snowfalls, the branches of the plant break from the heavy weight of the snow, therefore it is necessary to shake the snow from the branches. In the northern areas in winter, the main trunk of the plant should be insulated, protecting it from frost.
In spring, dead branches are cut from a plant; young plants can be cut to form a crown.
The main dressings are applied under lagurnum twice a year. In the spring the plant is fed with nitrogen fertilizers, which stimulates the growth of green mass. Before leaving the plant in a dormant period, make potash and phosphate fertilizers.
For the successful reproduction of culture, all known methods are suitable:
- seed way
- reproduction by layering
- division of the bush.
The main method of breeding breeches - sowing seeds.
Tip! The shell of the beans is very strong and strong, before sowing it is filed, or treated with emery cloth.
Seeds are not subject to long-term storage, they should be sown immediately after harvest. In the pre-prepared furrows lay out the seeds, lightly sprinkled with earth. When sowing, the beans are buried in the soil to a depth of 1 cm. Often self-sowing is formed around an adult bush. These seedlings can be used for planting. Flowering in this case comes in 5-6 year.
Vegetative propagation of culture by layering occurs according to the classical scheme: a branch of a tree is bent down to the ground, pinned and dug around with soil. The branch of a bobovnik for a year turns into a strong tree, which is planted in a permanent place in spring.
The propagation of bobovnik by cuttings is used for hybrid varieties that better preserve their decorative qualities. Cuttings are cut from the tree, leaving at least 3 live buds on them. Planting is carried out in greenhouses, in a light ground, ensuring uniform watering of the cuttings. Young plants develop very quickly. A year later, they are planted in the ground.
The division of overgrown bushes is suitable for breeding a variety, but adult plants hardly tolerate such an operation.
Pests and diseases of bobster
In hot and humid weather, baubnik bushes are often affected by powdery mildew. Mealy bloom appears on the leaves of the plant on both sides, gradually the leaf dries and disappears. The bare bushes are not decorative at all, therefore at the first signs of the disease it is necessary to treat the plant with special means.
Systemic fungicides for the treatment of powdery mildew are used in the dosage specified by the manufacturer.
At the first signs of powdery mildew, spraying of the leaves of bobovnik with water stops.
Pests do not particularly plague the plant. All parts of the bobovnik are very poisonous, especially for ripe seeds - they contain the greatest amount of toxic substances.
