When to cut a paulownia back to the ground?

Depending on the timber use, Paulownia can be cut back after anything from one year (for biomass growth) to 20 years (for large timber board).

Common practice is to harvest the Paulownia timber from the age of 5-8 for high quality wood. At this age, Paulownia trees can grow to the size equivalent of a 25 year old Teak tree.

For optimum timber production efficiency, under good conditions, harvest would be done at year 10.
