Larch - Tree of the Year 2012


The European larch (Larix decidua) has become Tree of the Year 2012. This is reason enough for us to present the beautiful and filigree conifer in an article. On this page you will learn everything about the characteristics, the location and the characteristics of the European larch.

As a garden tree, the larch is especially well suited in larger gardens: it loses its needle dress in winter, so it lets in more light than comparable evergreen trees such. Tannen. In spring, her light green needles are beautiful to look at and drive out early.

Larch: Properties

First of all: It is called larch with "ä" - the lark with "e" is a songbird. So if you offer a lark to plant, at least by ornithology or spelling has little idea.

Larch trees can become very old: In South Tyrol, three trees are known whose age is estimated at around 850 years. Average larches reach about 600 years - if they are not felled or overturn.

The larch is the only European conifer that loses its needle dress in winter. By this measure, the larch protects against the onset of frost.

Larch: location and planting

Larch trees are so-called light treesthat is, they need a sunny location. They are therefore ideal as a freestanding trees, possibly in the middle of the lawn of a large garden.

As far as the soil is concerned, the larch is moderately poor, if not undemanding: it needs slightly loamy soil. On sandy soils with low nutrient supply, however, it does not thrive well.

Actually, that is Larch a mountain tree, it grows in habitats up to 2500 meters on the valley slopes of the Alps. But even in the lowlands, the larch has become native through human intervention. In the German mixed forest, it grows preferentially in the vicinity of beech and other deciduous trees.

Metropolitan plantations of larches on busy roads and in industrial areas usually fail: the larch is not up to the exhaust gases from industry and traffic. In cities, a windy location with good air exchange should be respected.

Larch: diseases

Like every other tree larches are attacked by special pests. In particular, in oceanic layers - here are northern Germany, western Germany and parts of eastern Germany affected - but the larch can due to the alien climatic conditions larch cancer ill.

The disease is caused by a fungus, symptoms are an increased resin flow, dying shoots and no longer overgrowing wound craters on broken branch sites.

In heavy infestation and reduced needle formation of the tree is often beyond salvation, minor infestations can be eliminated by sawing off the relevant branch parts. If the strain is infested, a specialist should be consulted.

Special attention should be paid to a possible infestation with the Gray larch winder dedicate. Except for a massive use of pesticides, however, you can not do much about this pest. Especially with smaller trees you can still remove it "manually" - branch by branch.

In the Alps, gray larch worms ensure mass extinction for a veritable forest dying, especially since they are not picky after eating the larch shoots: Even pine and other conifers can be eaten.

Also the bark beetle, the Real pine weevils or the Arvenwolllaus can tackle the larch. Here should be consulted with a tree specialist consultation on the best control method.

Larch wood is the hardest among European softwoods and is only surpassed by the yew, which is poorly usable as a wood supplier. Trusses, wall and ceiling constructions as well as particularly durable and beautiful furniture are made of larch wood. Also in boat and bridge construction larch wood is of great importance.

As firewood, however, the larch is rather poorly suited, the calorific value of the larch wood has a similar value as pine wood and is rather rarely burned.
