How much to water
Watering of the jujube tree must be done for young seedlings and not for adult ones that prefer dry soils. So the jujube watering must be carried out in the hottest months and when there is no precipitation. This fruit plant adapts to many types of soil; It is also resistant to the calcareous and compact or stony and poor soil. However, to obtain good results we recommend a land rich in organic and well-drained substances. Jujube is quite common in Italy, but usually grows spontaneously and there are few known varieties, which vary in shape and size of fruits. The latter are the famous jujubes that appear green at the beginning of maturation, then more and more red. Their yellow-green interior is sweet and slightly acidic, but when they are too ripe they shrivel outside and acquire a high sugar content.
The jujube plant does not need much care, but the planting of root suckers and stakes must be done in winter in areas with a mild climate and in autumn if the temperatures are lower. However, the jujube also reproduces with the grafting, to be done in winter or in summer and considering the dimensions of the plant one wants to obtain and the type of soil. However, this plant can also be multiplied with seed or cuttings. In fact, if you want to make the jujube production with the seed you must keep it warm for three months and then in the cold for another three months, in the humidity of the sand. Germination will take place in the spring. Regarding the cutting technique, it must be taken from November to January, cutting a part of the branch where there is a bud. Remove the leaves at the bottom and place the twig in a container with light soil.
How to fertilize
The jujube tree likes a soil that is drained and fertilized in the autumn months with organic substances, while every year it is good to add complex fertilizer to the plant towards the end of winter. It is usually used animal fertilizer made to rest for at least 9 months. The first prunings can be made from when the jujube is planted and following the shape that you want to give to the plant containing the hair and removing old or sick branches. Jujube is harvested in autumn, but it can be done in different periods depending on the gradual ripening of the fruits; in fact the same ones ripen in September and are edible both from green or unripe and from red and very sweet. Jujubes are in fact small, fragrant and with a particular flavor; they are also grown in the nursery to produce the largest variety that looks like an apple due to its internal pulp.
Jujubes: Exposure and diseases
Where to place the pretty jujube tree? Certainly it is better to opt for a sunny place, but if the place has cold temperatures and frequent winds you should cultivate the jujube in a sheltered area. The plant is however rustic and resistant, as in winter it overcomes very low temperatures, even if it does not tolerate frosts and the unexpected cold of autumn. In the end, it is good to keep this plant in a temperate climate even if it is attacked by some pest and disease such as anthracnose, gray mold and rust or fruit fly, cydia molesta and incomplete carpomya. The jujube, however, does not even like the soil that is too acidic and damp because in similar conditions it does not develop well and therefore produces few fruits that have always been used in herbal medicine and medicine, as well as for the production of wines and liqueurs, such as the well-known "jujube soup".
