Princess Tree Care
Paulownia tomentosa
A very fast-growing, large-leaved shade tree that produces purple flowers in spring before the leaves. It needs a lot of space; it should not be planted with its roots close to structures.
Monthly care calendar
Timings are for a temperate Northern Hemisphere climate. In warmer areas tasks start earlier, in colder areas later; in the Southern Hemisphere shift them by six months.
- Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
- Pruning: While dormant, remove dry, broken, crossing and inward-growing branches so that air and light reach the inside of the crown. Remove side shoots when young to keep a single trunk; in old trees only clear the dry branches.
- General care: Good time for planting and transplanting.
- Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
