There are not less than 17 species of plants in the genus of paulownia trees. Commonly encountered species include, among others, P. Elongata, P. Australis, P. Catalpifolia, and P. Glabrata. Traditionally, these plants have been known to be native to Vietnam, China and Laos. They have also been known to grow in other countries of the Far East including Korea and Japan for many centuries. They have now been adopted in many other regions outside Asia due to their numerous benefits.
Generally, these trees grow deciduously. They grow to great heights averaging about fifty feet. They typically flower in spring and are at risk of attack from caterpillars. They should be frequently sprayed with insecticides to prevent damage. The fruits produced have a capsule that contains hundreds to thousands of tiny seeds.
These plants have a huge advantage in that they can be cultivated in virtually any soil type. They prefer areas with a low water table and thus can survive in very harsh climatic conditions. The major requirement is adequate sunlight throughout the period of growth. The use of fertilizer may help in improving yields.
There are many benefits that can be realized by growing these trees. The most common use involves reforestation in areas that have been destroyed as a result of uncontrolled human encroachment. Their use in this area is mainly due to their great regenerative ability and restoration of ecological systems. Related to the same is their ability to control soil erosion through intercropping. This helps maintain crop production.
The rapid growth rate makes them suitable for production of hardwood timber on a large scale. A number of species can be harvested in as little as 5 years. There is no need to plant new seedlings after harvesting. New trees are instead allowed to regenerate from the existing root systems. The timber that is harvested is pale, whitish in colour and has a straight grain. Other varieties may be silver grey, brown or red. The timber is very popular for various uses because it is resistant to rot and has a high ignition point.
A species known as Paulwnia fortunei is considered the fastest growing species. It is the best producer of hardwood commercially in the whole genus. This species has been the subject of reaserch activities for several decades now. It has been shown to grow very tall and exhibit huge apical dominance over the other species in the genus. Its other important characteristic is that it can grow in a wide range of climates and soils.
The trees that are chosen for timber production should preferably be grown to be very tall and straight in their first season of growth. The land for planting is typically ripped deep and ploughed in a rotational manner. There may or may need be the need for beds. Raising beds has several advantages to the farmer. For instance, it improves the soil drainage, the depth and the warmth particularly in the spring season. Planting of seedlings is done directly into the plots. Planting is usually done in October and November.
For a long time, paulownia trees have been used for producing resonators for use in musical instruments. Today, the same use persists but instead of stringed instruments, they are used for making low cost electrical guitars. The wood makes the core and lamination done using other types of hardwoods.
