Growing it

Propagation
seed, cuttings, suckers
When to plant
spring, autumn
Overwintering
No special winter care is needed as it is fully hardy in its native range.
In containers
Not suitable for long term container growth due to its massive size.

Suckers

  1. 1. Locate a healthy sucker away from the parent tree.
  2. 2. Carefully dig around the root to expose the connection.
  3. 3. Sever the root with a sharp spade.
  4. 4. Replant immediately in moist soil.

Plant in areas where its suckering habit can be managed or used to create a natural screen.

Grows well with

  • English Ivy · They often grow together in woodland settings, though ivy should be managed to prevent it from smothering the tree.

Similar species

  • Wych Elm · It has larger leaves and is generally more cold tolerant.
