Orange trees are known from holidays in Italy or Spain. The trees are especially beautiful when they bloom. Often there is a flower at the same time and there are small green and large, almost ripe oranges hanging on the tree.
The flowers smell strong, are white with yellow pollen. The contrast to the dark green leaves is nice to look at.
With us orange trees are held as potted plants. The problem with orange trees is that the summer and hours of sunshine are not long enough to let the fruits ripen. They do not get sweet, as one is used to them, and often they do not reach the beautiful orange peel. They stay pale.
The location should be bright and warm. If you put the orange tree outdoors in the summer, it is advisable to give it a sunny, but sheltered place. You put the tree out only when the temperatures are above 10 ˚C at night. In the living room, the plant must never be in drafts. One should not change an orange tree too often.
The plant substrate must be permeable to water and air. Therefore, it is advisable to mix expanded clay or perlite under the ground. Also, this should not be too calcareous.
Pouring and fertilizing
When pouring it is important to note that you must not pour too much, nor that the earth dries out completely. Ideal is to pour penetrating. That is, you pour so much that water can penetrate into every corner of the plant pot and at the end then the rest runs down below. The excess water must drain off. Then you wait a few days until the next watering. The top layer of earth should be well dried before re-pouring. This method is better than just pouring lightly every day. It is important to use low-calcium or lime-free water. Too much lime is the orange.
Fertilization takes place during the growing season every 3 to 4 weeks with a special citrus fertilizer. After hibernation, when the plants lack strength, fertilization with an iron fertilizer is recommended. You fertilize according to regulations, but 3 times a week, only a short time.
Orange trees can only be cultivated in Europe as potted plants. In winter you have to admit them, they are not hardy. There are several ways to overwinter the lime tree, either warm or cold. The best way to hibernate in an unheated room. He does not have to be really bright. Prefer to put something away from the window. Too much light usually leads to leaf fall. Temperatures between 5 and 12 ˚C are ideal. Only a little is poured. The cooler the room, the less water is needed. The bale should not completely dry out. It does not work. It is important that the root ball does not fall under temperatures of 13 to 15 ˚C. You can check this with a temperature gauge that you put in the ground. So that the temperature does not drop, the pot can be wrapped with bubble wrap. In addition, it is made from one or better two Styrofoam plates. At the temperature continues to take place a water exchange between the roots and the leaves. The leaves remain on the tree.
The best is an annual pruning in the spring. If the crown has become too light, can be cut more strongly. They then drive around the busier. Building a proper crown takes about 3 years. When cutting, of course, some flower approaches are cut away with. So do not cut too much, rather extend the cut over several years and always cut away little. Of course, you can make a radical cut in one year, but you can do without flowers and fruits for a year, but you have everything ticked off all at once.
Making orange tree blossom
If you have pulled an orange tree from a kernel yourself, you do not have to be surprised if it does not flower and of course does not bear fruit. This is sometimes the case with wild forms. Although there are wildflowers that have fruits, but they are different and usually not edible. Most first flowers first show up after several years. Often it is the too high temperature in the wintering is the fault, if the tree does not bloom. Nothing helps. You then have to put the plant cooler next winter (see above). Without cold, there is no flowering.
An orange tree can easily be pulled out of a core. However, these plants rarely bear fruit, although they also bloom. Better is, you buy a refined orange tree, which then bears fruit.
Diseases and pests
Often there is iron deficiency, especially if no special fertilizer is used. It is recognizable by light green or yellow leaves with dark green leaf veins.If deficiencies are already visible, usually only pure iron fertilizer helps. Spider mites are relatively common, especially if the air is too dry. In addition, aphids, shield or mealybugs may occur.
