Overwintering
No special winter protection is needed for this hardy native tree. Mulch around the base to help retain soil moisture if the winter is particularly dry.
In containers
This tree is not suitable for containers due to its massive size and extensive root system.

Seed

  1. 1. Collect the winged seeds as soon as they fall in late spring.
  2. 2. Plant them immediately in moist soil, as they lose viability quickly.

Plant this tree in areas with plenty of space to accommodate its wide root system and large canopy.
