The eucalyptus tree belongs to the Myrtengewächsen, whose over 100 kinds with nearly 5000 kinds are resident particularly in Australia and in the tropical America.
Of the approximately 620 species of eucalyptus, most are native to Oceania, Australia and Tasmania; few species of these invariably evergreen shrubs or trees come from Southeast Asia (Indonesia with Malaysia and New Guinea). The oceanic species include, for example, the giant eucalyptus from Tasmania, which is over 90 meters high and next to the sequoia to the highest deciduous tree species in the world. Also from there, the eucalyptus forests are known, which form the habitat of koala bears.
Today, eucalyptus is also grown in many other tropical areas because of the fast-growing wood that is well-used by the paper industry. In Brazil, for example, there are many eucalyptus plantations. In addition, various species are used for the extraction of essential oils, menthol-smelling species distribute in house and garden many pests.
The eucalyptus tree is deeply rooted, aligns its leaves perpendicular to the sun and hides well before budding its flowers in a capsule, he has in the youth heart-shaped leaves, after some years then lancet-like adult leaf shape.
Eucalyptus tree - care
The general rule for the cultivation of eucalyptus trees: As a rule, eucalyptus trees are grown as a container plant, because you quickly reach the appropriate size due to their rapid growth. Good as a bucket soil it gets a mixture of compost, peat and sand, but be careful with too many nutrients, these can stimulate the growth unnecessarily strong.
From spring to autumn, the eucalyptus tree looks forward to a warm sunny spot in the open air, because he knows a lot of warmth and light from his native Australia. If necessary, some species should also tolerate partial shade. In the spring, a pruning should be done, otherwise the fast-growing tree tends to be too large for his bucket. Larger wounds must be spread with varnish balm. Do not prune roots. Normally the eucalyptus tree wants to be watered evenly (daily), whereby the soil must be well moistened. If it is hot, it should be watered daily vigorously, once the root ball dries out, the leaves can be irreparably damaged.
The eucalyptus, however, does not like waterlogging at all, and even exaggerated wetness in the area of the root ball is not good, so the bucket should offer good drainage. Incidentally, most species do not tolerate calcareous tap water. In areas with calcareous water (if that's the case, your water works tell you), it's best to water them with rainwater. If rainwater is not available, you should consider reprocessing the irrigation water.
From April to September he only likes careful fertilization, about every four weeks with container plant fertilizer. The fertilizer should contain little nitrogen, so that the eucalyptus tree does not grow too fast or better matures. Also, phosphorus should contain little fertilizer, compared to the amount of nitrogen are amounts of phosphorus, which requires a plant, anyway relatively low. However, eucalyptus can cause too much phosphorus, because the soil in its native Australia is low in phosphates. Fertilizers with a low proportion of phosphorus are usually softwood fertilizers.
If the tree has become too big for its bucket, it can be repotted in the fall. Most species are well tolerated, the root ball is set as possible without pruning in the new pot. After two days of pouring break, normal care follows. The repotting should be done in time before the change to winter quarters, so that the tree has a rest period.
Eucalyptus tree overwinter
- In winter, the bucket into the house, a real hibernation knows the eucalyptus not, he is as bright and cool as possible to hibernate.
- The ideal temperature for hibernation would be about 5 degrees in a bright location, which may be achieved in a conservatory, attic, or basement with window. Because from about +8 degrees they do not grow anymore. The soil must then be kept drier, drying of the root ball is also in winter necessarily to be avoided.
- If a place with this climate can not be found in the living environment, the eucalyptus can also be hibernated in warm conditions, and it will then be cared for as it is in summer.
- However, it will continue to grow at about 8 degrees plus, with the result that it needs a lot of light (with too little light, it would probably go down). That's why you then need plant lamps, at 150 watts per square meter at a temperature of 15 degrees were here made good experience.
Problems with the attitude there are in the eucalyptus trees in Germany mostly due to lack of light, and the tree is quickly too big in the bucket. If you then consider planting your eucalyptus, hardy eucalyptus trees are sold commercially. The commercially available eucalyptus species are now reaching a great variety, especially as seeds, from which you can grow and multiply your eucalyptus trees.
