Pauwlonia is widely used in Asia for furniture, decorative paneling and musical instruments. It is light and strong with a silky smooth finish and takes a wide range of stains. Plantation grown timber produces straight grained, knot free timber. Paulownia timber could substitute for broad leaf timber that is harvested from the tropical rain forests of Asia, South America and Africa.
At 3 to 4 years of age Paulownia trees can produce a very straight cylindrical pole with no side branches or deformities 18 feet in height and 10-12" thick. This log is light but very rigid and it will not sag under heavy loads, making it ideal for construction. In Shandon, China, 4 year old poles are now used as ridge poles and uprights and 3 year old poles are used as rafters to support concrete and clay tiled roofs. Villagers claim that the poles are stronger and less prone to sagging than the traditional conifer poles.
Paulownia can be sliced or peeled finer than any other timber and still maintain its structural integrity. In Taiwan, Paulownia is sliced to 1/1000 inch and veneered onto paper for decorative purposes. Paulownia veneer can be used to face composite timber products and make them more attractive. Most high quality veneer timbers are becoming increasingly expensive and harder to find as they normally come from broadleaf trees harvested from old growth forests. Veneer is the highest value end use for Paulownia timber.
Moldings and Architraves:
Paulownia is ideal to use for moldings, architraves and wall paneling as the wood is light, strong and finishes well.
Fast grown Paulownia has excellent prospects for pulp as it can be harvested on a three to four year rotation after which it can be coppiced and allowed to regrow. The timber's long strong fibers are light colored and require little bleaching. The Paulownia pulp yield per cubic meter of timber is comparatively low so it is best mixed with other timber pulps.
Once a Paulownia Tree is harvested, a new tree will grow from the old stump making it one of the best regeneration for timber plantation trees. The same root can generate a new tree every 8 to 12 years - up to 10 or more full size trees. Paulownia is moisture resistant, strong and lighter than any other US grown commercial timber. It offers an environmentally sound alternative to expensive tropical woods like Balsa, Teak and Miranti. It’s also a great alternative for old growth woods like Western Red Cedar and Redwood. Paulownia can save forests by producing sawn timber in 7-12 years and growing 2-4 times more lumber than most other commercial trees in the same time period. This is vital as the supply of exotic and hardwoods rapidly diminishes. Paulownia is proving to be one of those rare environmental solutions that can also make economic sense.

As I work with it, I like the wood more and more. I have found it to be rot resistant and termites do not like it. It dries easy and fast with little defect other than a light sticker stain if not laid with dry stickers. The Paulownia wood makes good paneling, and some here are starting to carve it. Paulownia wood has a nice finish and machines and glues well. You will have to remove the stump or it will sprout back.

Ha! Paulownia is the wonder tree that is going to save our rainforests. You can harvest it in 10 years; it's as light as balsa and as strong as hardwoods, has great grain and is a very sustainable product that can be used for anything. I know some HWS (hollow wood surfboard) builders that would pay good money for that wood in your area. There are lots of guys on the east coast who are buying it but they can only get container loads from Australia. And none of them can afford that for their hobbies. I think the going rate is about $10-11/bft.

There is a definite correlation between tree size and economic value. Although trees are limb pruned early on to improve microclimate and thereby reduce blister rust of juvenile trees, an equally important reason is to start creating clear boles. Eventually, trees are pruned free of limbs to an eighteen foot height. Since crop trees are headed for a long life and large diameter, this early limb pruning pays great economic dividends. Left to natural pruning phenomenon, the trees would have to reach 100 plus years before their trunks would be growing clear faces. And since there is a manifold differential between the value of clear wood and knot-studded wood in white pine lumber (or in any lumber or veneer for that matter) early pruning is dramatically valuable.

The quick growth of Paulownia is a double-edged sword. For the plantation manager, a profit is realized much more quickly on a smaller plot of land. But the return of land to any semblance of a natural state anywhere near your plantation is not at all likely, because of the prodigious amount of seed that Paulownia's produce, which is then spread far and wide by the wind, water, and animals. In other words, many worry that Paulownia is really an invasive species that will spread to other areas and over grow natural habitats.
