Andentanne turns brown - What is behind it?
The Chilean Araucaria (Araucaria araucana), often referred to as Andean fir, because of its South American origin, is actually a very robust plant. Even lower winter temperatures do not harm the primeval tree, but both too much moisture and wintry drought can lead to browning of branches and needles. On the other hand, the best way to prevent it is to help with the right planting.
Andentanne does not tolerate waterlogging
In their homeland, the tree grows on mostly volcanic soils, which dry out quickly, especially in summer. For this reason, the Araucaria is more adapted to dryness than to wet, even though it basically requires a constant humidity. Too much moisture - such as heavy and prolonged rainfall - or even waterlogging quickly lead to needles and branches turn brown and the tree, if no countermeasures are taken, dies. Quite often it can also come as a result of the moisture to an infestation with decay fungi and root rot.
Ensure good drainage
Such a scenario can only be counteracted by drainage that has already been done during planting. Make sure the soil is a loose, well-drained substrate. This can also be mixed with lava earth (or crushed lava rocks) to mimic the conditions in the Chilean homeland.
Winter dryness leads to brown needles
However, especially in cold, but sunny winters is not too much wetness responsible for the brown color of the Andes fir, but, on the contrary, too much drought. Kahlfrost does not damage the tree due to the low temperatures, but because the roots in the frozen soil can no longer absorb moisture. Additional, intense sunlight also leads to a higher evaporation, but the plant can not resume. As a result, the Andean fir dries up.
Pay attention to the location already at the planting
You can counteract winter drying up by planting the araucaria on the north side, where it is bright enough, but not too sunny in dry winters. In addition, you can mulch the root area of the tree vigorously with leaves and thus keep the moisture in the soil.
Tips
If in doubt, you can cultivate the Araucaria in the pot instead of planting the tree in the garden. In this way, you can best meet the required living conditions of Andean fir.
