How to irrigate
The medlar plant does not appreciate excessively moist soil and certainly does not tolerate water stagnation. Watering should be done in the early stages of plant development. The medlar, during growth, needs frequent watering during the summer periods, on hot days. Once you reach four years of life, you will have to water in the pre-flowering phase or after having harvested the fruits. Especially in southern Italy it could be necessary during periods with scarce rains to irrigate frequently, in the evening hours, being careful to use water at room temperature. These extra waterings are called emergency irrigations and are carried out for the entire duration of the dry period or in any case up to a lowering of the temperatures.
How to cultivate
The medlar plant needs some cultivation to be able to grow in health, but apart from the classic irrigation attentions in the early stages of cultivation, fertilization and pruning do not need many other treatments. As for the soil, it is important that it is free of weeds and is rich in nutrients. In medlar intensive cultivation weeds are used to avoid weed development. The grass must be kept at a limited height and must be cleaned during the autumn by raking the leaves. Pruning residues must also be eliminated because they are a possible source of fungi and various diseases. In order to limit the damage of hail it is useful to use anti-hail nets, in this way the medlars are not damaged.
How to fertilize
The fertilization of the medlar plant is usually done during the spring season using compost or mature manure. The most widely used fertilizer is animal manure, but as the needs of the medlar vary, additional specific fertilizers with different proportions between the elements may become necessary. Before fertilizing it is necessary to carefully analyze the nutrients present in the earth, carefully evaluating the deficiencies to be able to intervene. For those orchards that grow only medlar plants, 200 grams of nitrogen, 280 grams of potassium oxide (K2O) and 180 grams of phosphorus pentoxide (P2O5) are required for each plant, to be given annually. Administer in such a way that the nitrogen is divided into equal parts during the pre-flowering and the beginning of the spring season.
Medlar: Diseases and Remedies
The diseases that could attack the medlar are very common and affect equally the plants for the production of the medlar that the plants cultivated for ornamental purposes. The medlars cultivated with ornamental purposes could be more accused of those leaf diseases caused mostly by fungi. Fruit plants, on the other hand, if the disease is mild, may also have no particular symptoms except for certain diseases that attack both the foliage and the loquats. The diseases that mostly affect the medlar are from fungi and can be prevented by conscious irrigation and the elimination of the infected parts. Other causes of diseases are induced by a bacterial infection called bacterial fire blight. In this case it is necessary to use specific products that can be purchased in specialized shops.
