How much to water

Paulonia Tomentosa is the most widespread variety and its flowering occurs around April and May, while in autumn the plant produces its fruits which remain on the tree to open in spring and release the seeds. Young Paulownia plants need little watering in the warm months, while adult trees only use rainwater. But in the first year of planting it is necessary to water abundantly and if it rains a little even every ten days. This plant features beautiful dark green leaves that fall in autumn, its bark is very ornamental and the flowers look like trumpets which are usually purple in color. They bloom in spring, but the buds come out in autumn and decorate the branches of the tree throughout the winter, only to open in the first warm and sunny days.

How to cultivate

In spring Paulownia is grown with the dark seeds of dried walnuts, then the seedlings will be planted. But always in spring this plant can also be grown with branch or root cuttings. The latter must be performed in November by taking small parts of the root that must be placed in a mixture of peat and sand, to be kept in the dark and at a temperature of 20 ° C. Only in February can they be moved to the light until the first leaves appear. While in April they will be placed in suitable and repaired containers. It will finally be in autumn that they will be planted. Paulonia is an oriental tree and more precisely Chinese. In these places it is held in high regard both for its very precious wood and for its rapid growth which favors a valuable energy use.

How to fertilize

To fertilize the Paulownia it is recommended to distribute a mature organic fertilizer at the base of the plant in spring, then proceed with fertilizations that dissolve slowly in the soil once every year. The Paulonia has no major soil problems and adapts without difficulty, but the land must be well drained. To obtain excellent results, the soil must be fresh and rich especially in summer and for young plants. Furthermore, stagnant water must not be present as it would cause serious diseases to the roots, perhaps during growth. Paulonia also does not need to be pruned, but it is good to remove the dead branches. At the limit it will be possible to intervene on the smallest and lowest branches, because if the big branches are cut they do not heal easily with consequent proliferation of fungi. This plant reacts well to ground level cuts to grow more trunks. With this method you can get a large bush even three meters high, but without flowering.

Paulownia: Exposure and diseases

Paulonia loves the sun and the light it needs to grow; it does not fear the cold and frost and not even the summer heat. It adapts to different terrains and climates, in fact it lives well even at 25 ° C. To maintain its splendid flowering it must be sheltered from the cold winds that could dry out the buds. Therefore, it is recommended to place it near a south-facing wall, which absorbs heat during the day and releases it at night. Paulonia is not particularly prone to diseases or parasites, but in humid and hot areas it is possible that the plant is attacked by powdery mildew, to be defeated with sulfur or similar and specific products. Armillaria can also be a problem as there is no suitable cure; it is only necessary to prevent it with well-drained soil and decreasing watering. Furthermore,
