Cotoneaster lacteus

How to carry out irrigation

The Cotoneaster lacteus hardly tolerates drought; in fact, it needs constant and frequent irrigation during the summer, especially during the driest periods. The soil must never remain dry for too long: this, in fact, could cause problems for the flowering of the specimen. On the contrary, in winter, and in particular in the case of abundant rainfall, it is essential to reduce watering, so as not to subject the plant to water stress. Stagnant water is really dangerous, as it often causes root rot and other types of fungal diseases. It is suggested to irrigate using the sprinkling or drip technique: through mechanisms called drippers it is possible to administer water resources directly to the roots.


This plant multiplies both by semi-woody cutting and by sowing; it is necessary to carry out the plant in a container full of universal soil and peat, mixed with a little sand. After a few months, the plant can be transplanted into a larger container, or directly into the garden. If you want to create a hedge, the cultivated specimens should be planted at a distance of about 80 centimeters from each other. The recommended soil is well drained, so as to avoid the feared water stagnation; periodically it is advisable to mix residues of straw and dry leaves with the soil, in order to make it more fertile. Pruning should be done at the end of spring, using sharp tools to make clean cuts, and clean ones to avoid infections.


Fertilization must be carried out three or four times a year, using a slow release granular fertilizer to be buried in the root area. The product must be ternary, that is rich in potassium, phosphorus and nitrogen, the three indispensable macroelements: they must not be lacking in the plant, since their deficiency inevitably leads to slow development and a general state of weakness. Potassium, in fact, is essential for the synthesis of proteins and for the absorption of sugars and water, phosphorus supports metabolism and rooting, nitrogen helps the growth of the vegetative parts and tissues. Also important are microelements such as magnesium, manganese, zinc, copper and iron, which in turn must be included in the fertilizer used.

Cotoneaster lacteus: Exposure, diseases and parasites

The exposure of the Cotoneaster lacteus can take place both in sunny and semi-shaded environments; it must also be borne in mind that bad weather and intense winds can seriously damage the flowers and leaves of the plant. Among the diseases can occur the bacterial fire blast, caused by the bacterium Erwinia amylovora, which manifests itself with the formation of spots and necrotic areas on the foliage and with the drying of the flowers; currently there are no effective remedies, so it is essential to take preventive measures such as careful periodic control. Among the parasites, on the other hand, there are aphids, also called plant lice, which feed on the sap by perforating the leaves and cause the transmission of various viruses. A suitable solution is nettle macerate.
