How to water the cornus kousa

The cornus kousa has large roots that sink into the ground and smaller rootlets that absorb water and nutrients. The size of these roots is rather small and therefore it is good to provide the cornus kousa with moderate amounts of water. If you proceed abundantly, it will tend to cause asphyxiation and consequent rotting of the roots. It is possible to increase the quantity of water supplied in the case of periods of high drought. In addition, it is good to check the humidity of the soil before proceeding with an irrigation. If the soil is still wet from the previous time, it is not necessary to water the plant again. The cornus kousa it does not present particular needs as regards the type of water to be used in wetting.


The cornus kousa needs different exposures depending on the area in which it is located. If we are in Northern Italy it is good to expose the plant to the sun or in a semi-shaded area. On the contrary, in the South it is good that the cornus kousa can benefit from a shady place, especially during the hottest hours of the day. As far as temperatures are concerned, the plant does not seem to fear extreme climates and resists well both in particularly harsh cold conditions and in the presence of sultry heat. As for pruning, it is recommended to proceed sporadically to shorten the branches that are too long and thin or by removing the dry ones. The multiplication of the cornus kousa takes place by layering. We proceed by burying a branch of about 1 or 2 years of age in spring. Usually,

How to fertilize cornus kousa


As for the fertilization of the cornus kousa it is necessary to proceed only once a year. It is recommended to fertilize the plant in March and use a slow release low-mineral fertilizer. It is important that this fertilizer contains the three basic chemicals (nitrogen, phosphorus and potassium) at a balanced level. The most suitable soil for the cultivation of cornus kousa must be neutral pH and rather loose and deep. In the event that the substrate is too dense and clayey, the development of the plant would be nil. It is also essential that the soil is very well draining. The cornus kousa in fact absorbs water very slowly and a substrate of this type allows to avoid the formation of water stagnations, primary causes of root rot.

Cornus kousa: Diseases and remedies


Among the main diseases of the cornus kousa are the pathologies generated by poor management and cultivation of the plant. For example, when you supply an excessive amount of water, you risk causing water stagnation. These stagnations are the primary cause of root asphyxia and consequent rot. Root rot could even lead to the death of the plant itself. Furthermore, by generating a particularly humid environment around our cornus kousa, it is possible to favor the attack by fungal species. These microorganisms prefer environments of this type for their development. Generally, it is possible to notice their presence through spots that appear on the leaves. In the event that infestation by fungal species is ascertained,
