The peach tree is a tree that fears drought; it is therefore necessary, especially during the summer season, to proceed with regular watering, more abundant during the hottest months. However, water stagnation, which is a widespread cause of rot, must be avoided, and it is therefore important to irrigate more or less frequently depending on the rainfall. It is necessary to give the plant a higher quantity of water during the ripening phase of the fruits, as, otherwise, the peaches will be too hard. Drip irrigation, also known as sprinkling, is widely practiced, which consists in distributing water in the form of thin jets and allows a considerable saving of water resources; The sliding method is also useful, as it requires a sloping ground.
How to grow and care for peach trees
This tree adapts to different types of soil, but it is essential that the soil is not impermeable and is instead well drained, so as to avoid the danger of water stagnation. The planting must take place, if possible, in autumn, in a hole about 60 centimeters deep and twice as wide; it is suggested to place some cornunghia on the bottom, and to immerse the roots in the mud before implantation. Obviously, as a preliminary step, it is important to work the soil and remove weeds. Pruning should be done carefully, limiting yourself to cutting any diseased parts and dry branches, and paying attention to disinfect the resulting scars; for this purpose, shears that are well cleaned and sharp enough to cut cleanly must be used.
The peach tree needs, for fertilization, products characterized by the presence of the three essential macroelements: nitrogen, phosphorus and potassium. The quantity of nitrogen, however, must not be excessive, as this would lead to an overabundant growth of the vegetative parts and, consequently, to the weakening of the plant and to a more limited fruiting. The supply of phosphorus and potassium must be greater, to ensure excellent fruit quality and to strengthen the crown and roots of the tree. No less important are microelements such as manganese, copper, magnesium and iron: in particular, the latter is essential for preventing leaf chlorosis. Fertilization must be performed at least once a year, in addition to that carried out at the time of implantation with manure or cornunghia.
Peach cultivation: Exposure, pests and diseases
Sunny, moderately ventilated and not too humid places are recommended for exposure; the plant tolerates low temperatures, but not late frosts that could cause damage. Also dangerous are parasites such as the fruit fly and the aphid. The first feeds on the fruits, devouring them from the inside and causing them to rot and fall, and can be eradicated with specific insecticides; aphids, on the other hand, cause perforations in the leaves and branches and require special aficides, as well as natural solutions such as nettle macerate. Among the fungal diseases, powdery mildew should be mentioned, which manifests itself as whitish molds, which is why it is also called bad white, and which requires fungicides; the so-called bubble is also widespread, against which copper-based products are recommended.
