How to grow Eurasian Aspen
Planting
Plant bare-root in winter, well away from buildings and drains — poplar roots are vigorous and can affect foundations on shrinkable clay. It suckers freely and will form a thicket, which is useful in a wild planting and a nuisance in a border.
Pruning
Little needed. Remove dead wood in late summer. Suckers will need pulling or mowing off regularly if you want to keep the tree as a single stem.
Propagation
Suckers can be lifted with roots attached in winter, which is much easier than growing it from the very short-lived seed.
Pests and diseases
Poplar rust causes orange pustules on the undersides of leaves and early leaf fall. Various leaf beetles feed on it without serious consequence.
Value to wildlife
Supports a good range of invertebrates, including several moth species, and the early catkins provide pollen well before most trees are out.
Notes
The flattened leaf stalks make the foliage tremble in the lightest breeze, which is the reason to plant it — the sound and movement are the point. It is fast-growing, short-lived and best given room in an informal setting.
