About soil condition, Paulownia tomentosa prefers deep, rich, moist soils but is moderately tolerant of wet soils and can even tolerate some standing water for short periods of time. It is not tolerant of dry or poor soils.
Like the other trees, the Paulownia tomentosa tree grows best when it receives plenty of sunlight. However, it is more tolerant to shade than other trees. It will still grow and prosper in shady areas, but it will not reach its full potential. For this reason, it is best to plant the tree in an area that receives at least six hours of sunlight each day.
The temperature condition for growing paulownia tomentosa is warm. The best temperature for growing this tree is between 21 to 32 degrees Celsius. It can survive in lower temperature but the growth will be slower. In addition, the tree prefer full sun to partial shade.
Ideal humidity condition for this plant is 50% and above. Under these condition, the plant will be able to thrive and develop properly. anything lower than 50% will stunt the growth of the plant and make it more susceptible to diseases and pests.
For the fertilizer, this kind of plant prefers rich, organic materials. It is especially important to keep the Paulownia tomentosa well-fed during the growing season, as this will encourage lush foliage growth. During the dormant season, from late fall to early spring, it is best to withhold fertilizer to give the plant a rest. As for the roots, they are relatively shallow and fibrous, so be careful when digging around them. It is best to water the Paulownia tomentosa deeply and less frequently, rather than lightly and often.
Pruning is an important part of plant maintenance for the paulownia tomentosa. This fast-growing tree can develop weak and misshapen branches if not pruned regularly. Pruning also encourages new growth, which can be helpful in restoring a damaged or overgrown tree.
Propagation of paulownia tomentosa is typically done by rooting stem cuttings taken from the tips of young branches. Cuttings should be taken from healthy, disease-free plants and should be 6-8 inches long. Cuttings can be taken year-round, but those taken in late spring or early summer will usually root the quickest. Cuttings should be placed in a well-drained potting mix and kept moist until roots begin to form. Once roots have formed, the new plants can be transplanted into larger pots or into the garden.
Usually, the plant growth rate is about 3 to 10 feet per year, depending on the growing conditions. Good light, well-drained soil, and moderate moisture are ideal. Fertilizer is not necessary for young trees, but may be beneficial for trees that are not growing well.
Common problems for this kind of plant are root rot, crown rot, and leaf spot. Root rot is caused by too much water, while crown rot is caused by too little water. Leaf spot is caused by a fungus. All of these problems can be controlled by following a proper watering schedule and by keeping the plant clean and free of debris.
