Corkscrew willow: care and varieties

The corkscrew willow is particularly popular with its twisted two-formations as a decorative garden and park planting or as a material dispenser in floristics. She is quite easy to maintain and an interesting candidate for bonsai fans.

ancestry

The corkscrew willow, botanical Salix matsudana, is a native to us within the genus of willows. She was bred from the weeping willow (Salix babylonica), which in turn comes from East Asia.

growth

The corkscrew willow grows about a meter per year when its location meets its preferred conditions. Altogether, at 8 to 12 meters, it reaches a slightly lower height than the Weeping Willow and forms a shrubby to tree-like shape. The corkscrew grazing becomes only about 10 to 15 years old.

Responsible for this are, among others, the name-giving corkscrew-like twisted and strongly winding branches on the long, towering branches. They form an extraordinary, characteristic sight and at times an almost grotesque overall silhouette.


An overview of the growth characteristics of the corkscrew willow:

Which location is suitable?

The Salix matsudana likes it sunny to partially shaded. If the spot is too dark, its growth is reduced significantly, and growth damage may occur as well. In terms of soil conditions, the corkscrew grazing is quite modest. This is thanks to their extensive, effective root system. It thrives in almost all soils, both acid and alkaline, sandy as well as loamy. Only enough moisture should be guaranteed. What the corkscrew willow is good for, is a good loosening of the soil, for example, by horn shavings, which mix in the planting in the excavation. If the soil is particularly lean, you can also add some compost.

Even a corkscrew willow kept in a tub culture should stand sunny. The substrate may consist of simple potting soil, possibly mixed with some sand and volcanic rock.

use

With its rapid growth, Salix matsudana is a popular candidate for tree plantings that are expected to skyrocket, such as in newly landscaped gardens or parks, especially where a natural boundary is quickly formed or a gap is closed.

In addition, it has a high decorative value with its typically twisted, twisted branch formation and is a popular material for florists. In bouquets and floral arrangements can be set attractive structural accents with their branches. Also quite "pure" in the vase, individual Korkenzieherweidenäste make very pretty.

The corkscrew graze is also interesting for fans of bonsai culture: their fast growth and their flexible, structurally rich branches provide a good basis for interesting formation education.

The benefits of corkscrew grazing

Pour corkscrew pasture

If the corkscrew grazing is cultivated as a high stem in the field, it generally does not need to be supplemented with water when it is fully grown. At most in long, hot dry periods in summer, you can occasionally water them with rainwater.

Of course, you first have to water a newly planted young tree well and care for it in dry phases a little more tightly meshed.

Even more necessary is the regular water supply course in a corkscrew willow in the tub culture. In this form, it has a higher water requirement and, of course, can not store so much water in the pot substrate. You should water a corkscrew willow in the bucket regularly and relatively extensively, so that the root ball will not dry up until the next watering. The lime content of the water is relatively insignificant for the corkscrew grazing.

Fertilize corkscrew willow properly

The corkscrew pasture as a field bush / tree does not really need to be fertilized. With a little bit of compost and horn shavings in the plant hole when setting you can of course do something good.

The situation is different with the tub culture. Here is the space for the very far-reaching roots is very limited, so you should help the corkscrew willow here with a little extra nutrient. It's best to give her some green plant liquid fertilizer every two weeks. You should refrain from cheap, aggressive mineral blue grain fertilizer.

Cut corkscrew properly

Cutting is an important issue in corkscrew grazing - in this respect, it probably claims your care the most. Her rapid growth requires her to be cut back and squeezed every year to stay healthy and fresh. Plus, it's so much easier to keep in shape aesthetically.In smaller gardens, regular pruning may also be necessary for space reasons alone.

The pruning is best done in early spring, when the tree is still before the first massive growth spurt and its branches are still bare and clear. They best start by removing old, dead branches, so that the energy can be put into the sprouting of the healthy branches over the spring and summer. Then you can make the shape cut, which is more depending on your concerns, the space limitation or the visual aesthetics.

In older age, it is advisable to radically cut back the corkscrew pasture. This promotes a more vital renewal and a refreshing of the branch texture.

The cutting rules at a glance:

A tip: The fact that the pruning of the corkscrew pasture should fall into the early spring, meets well: Because the beautifully drilled branches are ideal as a fresh, decorative material for Easter bouquets! Hängeschmuck as blow-out eggs can also be best hung on the branch coils.

implant

The best time to plant a corkscrew pasture is autumn before the first frost - so she has the opportunity to train her root system well for now. When planting, you should first of all dig out a generous hole. The root ball of Salix matsudana spreads namely strong and needs a lot of space for development. It is best to add a few horn shavings to the excavation for loosening and long-term fertilization. You can also add compost, but this is only necessary on particularly lean soil.

The tree disc around the inserted young tree you well firmly and pour well. Give him a little support against wind with a support pole and tie him with a jute.

To remember:

How do I properly plant?

A transplanting should be avoided if possible with the corkscrew grazing. First, this is debilitating for every plant. On the other hand, Salix matsudana is so undemanding in terms of its standard that, at least in this respect, a change of location will generally not bring much if the tree shows defects. Also against it speaks that the corkscrew willow is not getting very old - in such a short life you should save her a transplant so even more urgent.

If it takes up too much space, you can better cut it back radically. That tolerates them even in old age without any problems.

Above all, if you insist on transplanting, you should dig up the corkscrew grazing very generously, as its root system is essential to it and expands very far. When digging new, you are just as generous and loosen up the substrate well.

Increase corkscrew grazing

It is not hard to grow a corkscrew willow. For this purpose, it is best to simply use something from the blend, which accumulates anyway at the annual pruning. From the cut branches cut off a shoot about 15 to 20 cm long with a few buds and give it a complete decoction.

Preserve this wooden cuttings for the winter and put them in a pot with a substrate of soil and peat the following spring. Set this to a bright, sunny window seat and keep it evenly moist. You can also apply the well-proven film method, by covering the cutting with a foil and thereby provide him a uniform warm humid microclimate.

offshoot

Offshoots are the most common method for the propagation of corkscrew grazing. Theoretically, of course, the sowing is possible, but in view of the simplicity and high Gelingrate of wood cuttings you should rather refrain from it.

In the bucket

Because of its pretty branch and its good controllable growth, the corkscrew willow is also ideal for the tub culture. Here are a few things to consider. First, pay attention to a sufficiently spacious, loose and always moist substrate. Provide a loose drainage of lava chippings or expanded clay hearders and amounts of soil best also organic slow-release fertilizer such as horn shavings and some compost. During the growth phase you should also give some green plant liquid fertilizer every 14 days.

The location should be bright and sunny. In winter, the winter hardy corkscrew grazing in the bucket does not need to be brought into the house. Protect the root ball a bit from severe frost by wrapping the pot in sackcloth and / or covering the ground with fir branches.

bonsai

Thanks to their fast, vital growth and flexibility, the corkscrew grazing can also be good for bonsai. To do this, it's best to start by growing a wood cotter as described above. When it has reached the desired stature height, consistently shorten the upper end shoots and bring the mini-tree out to exaggerate laterally and develop a broad, shapely crown. These can then be sharpened to their whims in their contours and enjoy the compact, meandering winding branch.

Diseases

Unfortunately, diseases are a topic for corkscrew grazing. Although they are undemanding in the site conditions, but quite susceptible to fungal diseases, especially for

Marssonina mushrooms

An infestation can be detected in discoloring and drying leaves. At an advanced stage, the tips of the branches may also turn dark and form growths. In this case, remove all diseased parts of the plant quickly and thoroughly as far as possible and dispose of them in the residual waste. In stubborn cases, you can also help with a chemical fungicide.

Weidenschorf

Also for willow scab corkscrew grazing is quite vulnerable. The symptoms of this fungal disease are very similar to those of the Marssonina mushroom and the countermeasures are basically the same.

Preventing fungal infestation, you can supply your corkscrew grazing increasingly with repellent potash and phosphorus.

pests

The corkscrew pasture is also haunted by pests. These include above all

Willow leaf beetle

The shiny, small, round willow leaf beetle can almost completely eat up the corkscrew willow with its immense appetite. Especially with a young tree you should definitely resort to an insecticide here.

Weidenbohrer

In the pasture borer, a moth species, only the larvae are dangerous. They eat after hatching under the bark through the entire bark and eventually fume out a vinegar-like odor. Most of the damage is then already massive. The fight is difficult - the adult moths can be collected, the under the bark do not eat larvae. Infested shoots should simply be cut out completely. In the worst case, the corkscrew pasture is beyond saving and must be felled.

Is corkscrew grazing toxic?

Pastures are generally a harmless genus of plants from a toxicological point of view. So it's the same with the corkscrew willow. It poses no danger to humans or animals. So if infants and / or animal housemates live in your household, you do not need to worry about either planned outdoor planting or pot culture.

Tips

You do not need to miss the many blends during the annual pruning: The branches of the corkscrew pasture contain valuable auxins, which, as a natural growth hormone, also stimulate other plants to root. Just pour the finely cut shoots with boiling water and let the infusion draw for 24 hours. The sown brew can then be used for any rooting project.

sorts

The best known corkscrew grape species is the Salix matsudana tortuosa. In addition, however, other forms of culture are cultivated with special properties, such as

Salix Caradoc

This variety is called in German gold corkscrew willow and has its special charm by a golden autumn color. As a result, she also has a different jewelry value, apart from the typical winding branch structure. The branches are also particularly zigzag-shaped wound. The corkscrew willow has a shrubby habit and is about 6 m high. Like the Salix matsudana Tortuosa, it needs a sunny spot and a moist soil.

Salix matsudana Pendula

This corkscrew willow has, in contrast to Salix matsudana Tortuosa, hanging branches, reminiscent of a weeping willow. Otherwise, it is similar to the tortuosa from habitus and site requirements.

Salix erythroflexuosa

Their branches are turned particularly intense and have a reddish, attractive color. The long, lanceolate leaves are usually also wavy in itself. The shrub forms an upwardly widening silhouette and is about 3 to 5 meters high.
