Albitius
Lankaran , or Lankaran acacia, or Albitius silk (Albizia julibrissin)
belongs to the legume family and is a large deciduous tree up to 10-12
meters. He spreading umbrella-like crown, as some species of tropical acacias. Albitius delicate leaves , dissected into numerous small lobes. According
to some scholars , the birthplace of this plant - Lankaran ( which is
reflected in the title of a tree) , but it is spread much wider - from
the Caucasus to certain areas of Central Asia. On the Black Sea coast of the Caucasus are also feral Albitius , but they came from self-sown trees imported here .
Lankaran acacia - a plant of dry warm climate . I'm not known for its hardiness , but even in the coldest winter for our conditions ( with frosts down to -10 degrees ) Lankaran acacia trees are not damaged . However , in recent years Albitius become much less durable than before. In some places in the city are still preserved trees with a trunk diameter at the base of up to 70-80 cm, and lately they rarely reach half-meter diameter and dry . Apparently this is due to climate change. According to a local legend , earlier in our area in the summer was much drier and warmer , which is apparently more like this acacia .
Albitius light-requiring , it can not grow in the shade of other trees.
Lankaran acacia blossoms late, in the middle of May, when nearly all the trees have blossomed . Its abundant flowering and long - begins in mid-June and lasts until September or October , depending on weather. In autumn it is very long keeps the leaves (sometimes until the end of November) , the worth of a few trees in our climate. Albitius until the last moment remain green , and at one time can only destroy frost or strong winds .
Propagated Lankaran acacia seeds, cuttings , root shoots . Apparently , it must also reproduce and grafting , but I did not read that someone Albitius reproduce in this way, and he did not do .
Albitius seeds need stratification . In the literature are advised to carry a "hot" stratification : The seeds are soaked for 5-6 hours in hot water ( 60C ) , and then seeded . I apply the usual " cold" stratification , which are the seeds of our winter directly in the ground. When autumn sowing seed germination in the spring is about 80 %, and individual seeds can ascend through the year. In the first year Albitius seedlings grow slowly and rarely fall to reach a height of 20 cm feed up to them this time, I do not recommend - you may burn the roots of young plants. In addition, an excess of nitrogen fertilizer is delayed growing season of plants and timber seedlings may be difficult to ripen for the winter. Then in the case of severe frosts such plants might suffer or even die . Albitius fertilizing seedlings can be started from the second year of life , gradually increasing the dosage.
Vegetative propagation Albitius used more often. Some trees produce root shoots , which can be separated and plant out when the plants are dormant .
Cuttings Lankaran acacia satisfactorily , and you can use as a lignified and green cuttings .
Woody cuttings are cut with a yearly growth of last year. Take cuttings with 2-3 buds from the middle of the shoot, handle their rooting stimulants and put a permanent place in a loose fertile soil. After 3-4 months of rooting usually occurs at 70-80 %Green cuttings Albitius apply in July. Cuttings are also taken from the middle of escaping with a 2-3 buds , too, is treated with stimulants rooting , but 2/3 of the leaf blade is removed . Closely monitoring the moisture content of the soil, and usually by the fall in the 70-80% of rooted cuttings .
