This elegant tree fears prolonged drought; consequently, especially during the summer season, watering must be done regularly. In winter, however, and especially if rainfall is constant, irrigation can be reduced: it is important that the soil is always kept slightly moist, but at the same time it is essential to avoid stagnation of water, which can cause rottenness to the root system. To avoid a waste of water resources, sprinkling irrigation is recommended.
This method allows you to direct thin jets of water directly to the root area, thus avoiding the trunk and foliage, and to water the plant continuously or intermittently, depending on your preference.
Weeping willow multiplication usually occurs by woody or semi-woody cutting. An initial planting should be made in a container containing soil mixed with peat and little sand; after about forty days, when the first shoots begin to sprout, the plant can be transplanted into the garden. The ideal soil is soft, slightly humid, fertile and rich; it is essential that it, before planting the specimen, is worked with a spade, so as to overturn and aerate the clods.
Pruning must be done only if it is necessary, that is, to cut down branches damaged by fungal diseases, cold or by possible parasites. Occasionally it is advisable to mulch the soil with organic substances such as straw.

How to fertilize
The weeping willow should be fertilised annually, using natural substances such as mature manure, or with a granular fertiliser containing nitrogen, potassium and phosphorus in a balanced manner. All three macro-elements are necessary for the health of the plant; a lack of them can be really dangerous, as it causes a slowing down of the development and a general weakening.
Nitrogen helps the growth of the vegetative parts and the production of chlorophyll; potassium increases the resistance of the tree to cold and parasite infestations and supports the synthesis of proteins; phosphorus intervenes in the energy metabolism. No less important are trace elements such as magnesium, molybdenum and iron, which in turn must be included in the fertilizer.
Weeping Willow: Pests, Diseases and Remedies
The exposure of this tree is bright, sunny, but sheltered from the elements, which could cause serious damage. Attacks by parasites such as aphids are also dangerous: they are generally green or brownish in colour and tend to pierce the leaves, branches and shoots to suck the sap. They are responsible for a global deterioration of the specimen subject to infestation, and to eradicate them natural products such as garlic infusion and nettle macerate are suggested.
The tree can also be susceptible to fungal diseases such as rust; it manifests itself in dark spots that expand as the fungus progresses. It is essential to eliminate and burn the affected parts and to carry out treatments with fungicides based on sulphur and copper.
