Origins and peculiarities of eucalyptus
Theeucalyptus is a genus of trees comprising more than 600 species. It belongs to the myrtaceae family. It is a native plant native to Australia and more particularly to Tasmania. A few species, including eucalyptus globulus, have been introduced on the European continent as well as in North Africa and the United States.
Depending on the varieties, eucalyptus trees can measure from a few meters up to more than 90 meters high. They can have one or more trunks whose bark makes it easy to identify them depending on whether it is hard, smooth, fibrous, with deep furrows, flaky or easy to peel.
The foliage, persistent for the majority of species, changes radically as the tree grows. Their habit is mainly pendant, and their color of a brilliant green slightly silver. When persistent, the leaves of the eucalyptus tree contain tiny glands full of essential oil, giving them a powerful characteristic odor.
The flowers have a large number of stamens and have many varieties of color such as yellow, pink, red or white.
Theeucalyptus tree can be just as suitable for planting in the open ground in a garden (in hedges or as an isolated plantation) as it is for growing in pots on a terrace or balcony.
Uses of eucalyptus
Eucalyptus is a tree which can be used in many ways, in addition to its ornamental use in gardens of course:
- Its antiseptic and bronchodilating properties make eucalyptus a tree widely used in herbal medicine, aromatherapy and in the preparation of many drugs (in the form of infusion, essential oil, candies, capsules, syrups, balms, etc) to treat ENT ailments, coughs…
- It iseucalyptus flower that Australia gets its biggest honey production.
- The wood of the eucalyptus tree is also used to make furniture in the southern hemisphere.
The planting a eucalyptus is strongly discouraged in a garden of smaller surface, because this tree can quickly take a considerable size.
In France, the region most suitable for growing eucalyptus is the South thanks to its low-calcareous soil. But it is better to take care to place it in a place sheltered from the winds which are likely to dry it out, and, above all, in full sun.
To note : the eucalyptus tree secretes via its roots a substance which can prevent certain plants from developing; so remember not to plant it in the immediate vicinity of your flower beds.
Thewatering the eucalyptus can be generous because this tree appreciates wet grounds. However, it is necessary to wait until the water has well penetrated the ground to repeat the operation.
Watering should be less consistent in winter. At this time of year, we usually wait until the soil is dry before watering a eucalyptus.
Care and size of eucalyptus
The eucalyptus fears limestone and cold winds. On the other hand, it is not afraid of frost (down to -5 ° C) and it supports perfectly being in the sun with its feet in the water, especially during the growth period.
Aside from these few precautions, theeucalyptus maintenance does not pose any particular problem. No mandatory pruning, no fertilizer application and especially no mulching with its dead leaves because they are toxic to it.
For pruning: when you plant such a tree, it is useful not to forget that it will gain height but above all amplitude. It is possible to prune it in winter, which will cause the trunk to swell and restrict its ascent to the sky. An annual eucalyptus pruning makes it possible to obtain a very aesthetic bush, but it is not necessary for its development.
Eucalyptus diseases are rarely serious, with the exception of eucalyptus plague (a form of gall) which is sometimes found in Mediterranean regions.
