Citrus aurantium is also known as pomeran, sour orange, bitter orange and sour orange.
The name Chinese Orange betrays the origin of this citrus.
In China, also known as Zhi Shi, a dried extract is made from the fruit, and it is especially the extract synephrine, which causes increased combustion.
The blossom will appear from the moment the weather gets hotter in May to the plant. The big white blossom smells pleasant and can not really miss a place near your terrace.
The fruits have a diameter of 8 cm and are flat at the top and bottom. As a result, the fruits are slightly oval.
The peel of fruit smells very aromatic and is bitter, orange / red in color.
The flesh is used for jam, marmalade and liqueur like orange bitter.
In spring, the citrus plant is allowed to go out again, do this after there is definitely no chance of frost.
Now the water need may be raised again, but keep it moderate (not giving too much).
Also give the 3 weeks of liquid citrus fertilizer like Citrus Focus to the plant, from April to the end of September.
The Citrus aurantium will react immediately and new shoots start to grow.
Grow shoots for too long as the citrus tree trimmes in autumn. This way you always keep the desired shape and height.
In winter, keep the citrus plant frost free in a lightest possible place. Few water, once a month is sufficient. No fertilizer anymore.
If the citrus tree is warmer than + 12ºC in winter, half a dose of fertilizer can suffice.
Winter hardness zone 11 (+ 2ºC).
