White poplar
Populus alba
A fast, silvery biomass tree for wetter or heavier ground — it roots easily, pumps minerals up and gives quick shade. Coppice it, but watch the suckers: it spreads and can turn weedy.
White poplar in a syntropic line
White poplar belongs in the Emergent layer as a Secondary biomass species. They frame the line. Rough in-row spacing starts around 1.9 m in a syntropic row. Good line partners include Apple, Elder. As a Secondary species it carries mid-term yield and structure while climax trees slowly claim the canopy.

How to manage it
Great for wet zones, riverbanks or as a fast windbreak/buffer line; roots readily from winter hardwood cuttings and pollards well for repeat mulch.
How to propagate
Push dormant hardwood cuttings into moist ground in winter; roots readily.
Guidance, not a guarantee — success varies by species and skill.
What to watch out for
Suckers aggressively from roots, especially if the trunk is cut or stressed, and is considered invasive/weedy outside its native range (e.g. naturalised in North America) — keep away from crop lines and structures.
Frequently asked questions about White poplar
Is white poplar frost-hardy?
Yes for winter cold in many climates — generally hardy to around -30°C when dormant, with high frost tolerance in the catalog. Flowering crops can still lose a season to late frost, so site them carefully.
What soil does white poplar need?
It does best on clay, loam ground, at pH about 5.5–8.
How much water does white poplar need?
Plan for a rainfall floor around 500 mm/year, plus medium irrigation once established.
Can white poplar handle wet or waterlogged soil?
Yes — white poplar has high waterlogging tolerance and copes with winter-wet ground.
What should I watch out for with white poplar?
Suckers aggressively from roots, especially if the trunk is cut or stressed, and is considered invasive/weedy outside its native range (e.g. naturalised in North America) — keep away from crop lines and structures.
