Paulownia Empress Trees thrive in temperate and subtropical regions with warm, moist summers and mild winters. They commonly grow along riverbanks, in open woodlands, and in disturbed areas such as abandoned fields and roadways.

Paulownia Tomentosa and Elongata Clones

Paulownia tomentosa and elongata clones are genetically identical individuals propagated from these two species through cloning. The cloning process involves taking cuttings or tissue samples from a parent tree and creating new, genetically identical individuals.

Cloning can effectively produce large quantities of trees with desirable traits, such as disease resistance, rapid growth, or high timber yield. Paulownia tomentosa and elongata clones are often used in commercial timber production, reforestation projects, and for ornamental purposes.

Both Paulownia tomentosa and elongata are fast-growing trees that can reach maturity quickly, making them ideal for reforestation and afforestation projects. Their high-quality timber, lightweight, strong, and durable, is highly valued.

Cloning helps ensure consistency and predictability in terms of growth rate, yield, and other characteristics. However, maintaining genetic diversity within a planting population is crucial for resilience against diseases and environmental stressors. As a result, it is recommended to plant a mix of cloned and non-cloned trees in any planting project.

Tree size and economic value are closely linked when it comes to paulownia. Early limb pruning not only reduces the risk of blister rust in juvenile trees but also initiates the formation of clear boles. Pruning trees to an 18-foot height ensures that crop trees reach large diameters and live long lives, maximizing economic benefits. Since clear wood is valued more than knot-studded wood in paulownia lumber and veneer, early and consistent pruning offers significant value.

Comment from contributor D:

The rapid growth of paulownia trees presents both advantages and drawbacks. For plantation managers, profits can be realized more quickly on smaller plots of land. However, the trees produce a large number of seeds that can spread far and wide by wind, water, and animals, potentially causing them to become an invasive species that overgrows natural habitats.

Planting Paulownia

When planting paulownia, choose a relatively flat site with good drainage, as the tree does not thrive in flood plains or low valleys where water can accumulate. Sandy loam is the best soil type for paulownia. To enrich the soil with nitrogen, consider planting a bean crop, such as soy, a year before planting the trees. Till and disk the land in parallel rows before planting. For biomass production, space the trees 5 feet apart in rows 15 feet on-center to accommodate mechanized harvesters.

Paulownia Care & Maintenance

Explosive growth rates can be attained with heavy watering and periodic applications of fertilizer. Terminal growth of 10 feet per year is not uncommon in ideal conditions. An annual branch trimming regime should be adopted to maximize the value and profitability of the plantation.
