Japanese medlar

How to water

The Japanese medlar tree does not live well in very humid soils and especially if there is stagnant water. The watering of this plant must be done in the early stages of development, during growth instead, it is necessary to wet them only on the hottest days of summer. After the first three years it will be necessary to irrigate before flowering and after harvesting the medlar. If we live in the south of Italy it could be useful, in times of greater drought, to irrigate possibly in the evening, using water at room temperature. These operations are called emergency irrigation and are done until temperatures drop and there will be heavy rains. The water requirement of the Japanese medlar should be around 2500 cubic meters of water per hectare.

How to cultivate

The Japanese loquat plant doesn’t need a lot of attention to get a big yield. Except for irrigation in the early stages of cultivation, some periodic fertilization and pruning no other care is necessary. The soil must be balanced with nutrients and free from weeds. In the cultivation of Japanese loquats, we usually intervene with grassing to block the growth of weeds. After pruning, you have to throw away the cut parts because sometimes fungi and parasitic insects lurk on them that could lead to diseases. To avoid damage caused by disturbances, when the orchard is built, protection nets are added, depending on the space available, preventing the medlars from being damaged.

Fertilization and pruning

Fertilizing Japanese loquat trees is usually done during the spring using matured manure. A widely used fertilizer is manure of animal origin, but this plant also needs special fertilizers with different nutrients. For fertilization, the availability of soil nutrients must be carefully checked and possible deficiencies in nutrients must be corrected. Regarding the pruning, it depends on the shape we want to obtain, it must be done immediately before the winter season because, if done in winter, the plant could die. Limited intervention is carried out on the branches that do not follow the desired shape and, during May, removing the suckers at the base. The goal to achieve is to have good internal ventilation, making sure that the light arrives in the right quantity.

Japanese medlar: Infestations and remedies

The Japanese medlar is sometimes attacked by many rather common diseases, which affect both plants cultivated for production and ornamental plants. As far as production plants are concerned, if the attack does not seem strong they may have no symptoms except for some diseases affecting the leaves and fruits. As for ornamental plants, on the other hand, they are very affected by leaf diseases caused by fungi. Fungi are among the most common diseases, such as medlar leaf spot, branch canker or powdery mildew. Other issues could come from a disease called fire blight. The Japanese medlar is also infested with some parasitic insects, such as the capnodio and the cochineal, to be eliminated with other predatory insects.
