The Paulownia Crop, a forestry Revolution

Plantation: Generally in spring. If temperatures don’t reach below -5ºC it is possible to plant throughout the year.

Technical cut: Cutting the tree down to ground level (4cm approx) during dormancy period (winter) with the purpose to form a highly valuable straight trunk knot-free . The technical cut is only made once the tree reaches a minimum of 5-8cm on the base.

Sprout Selection: Choosing the straightest and quickest growing sprout after the technical cut. The others are to be removed. The one we choose will form our commercial log.

Prunning: For timber production, prunning the young axillary buds on the 2º and 3º year until obtaining a clean log of 5-6 meters free of branches (not the leafs).

Land clearance: Only during first and second year. Paulownia tolerates intercropping.

Sprouting: Paulownia sprouts again after being cut, providing even a higher productivity. Between 5 to 6 crops for biomass with cycles of 3-4 years and 3 and 4 crops for timber production with 8-10 year cycles.

Agronomical aspects

Type of soil: Paulownia adapts well to all type of soil, except high waterlogging soils, with high salt concentration or high percentange of clay.

Recommended PH between 5.0 and 7.5

Fertilizing: 

Recommended subsoiling: minimum deph of 80cm.

Irrigation: Depending on area, climate and soil humidity. For humid climates irrigation is not neccesary.

Optimum water needs: 2.500m3 per hectare.
