How to water
As for the irrigation of paulownia, it is necessary to proceed only on rather young plants and it is important to carry out the wetting with a certain moderation. The plant, in fact, withstands even periods of short drought and excessive irrigation would only lead to the formation of water stagnations and to the submergence and asphyxiation of the roots. Water stagnations are the primary cause of root rot which quickly leads to paulownia death. As for the specimens of paulownia more adult, on the other hand, wetting can be largely decreased or almost completely interrupted. Larger plants are able to settle for rainwater alone to survive. As far as the type of water to be used during the watering is concerned, the paulownia does not seem to have any special needs.
How to cure
The paulownia prefers an exposure in particularly sunny areas, even if it is able to adapt if it is positioned in semi-shaded places. It is a rather resistant plant to various climatic conditions, it bears both cold and torrid heat. Its multiplication can occur through various methods such as: air layering, seed or cutting. If the layering is used, the paulownia daughter that will be obtained will be a bonsai. Instead, as regards the reproduction by cutting, it is necessary to wait a year before placing the branch removed from the mother plant. As regards seed multiplication, on the other hand, the precaution to be adopted is the planting of these seeds in rather sunny areas. The new paulownia will tend not to grow properly if the seeds are scattered in a semi-shaded area.
