Green Paulownia is very tolerant of adverse soil conditions but is sensitive to
water logging. Heavy peat or sandy soils work well; clay and rocky soils do not.
Loose, well-drained soils with a pH between 5 and 8 are ideal. Green Paulownia
can grow well even in highly saline soils and in nutrient poor soils, where its
ability to selectively absorb Ca++ and Mg++ ions gives it an advantage. As a
consequence of its hardiness, Green Paulownia has been used with great
success in mine reclamation projects.
