Expert tips
The key tip
White poplar grows very fast and produces abundant suckers if damaged: avoid any injury to the trunk or roots. Plant in well-drained soil; it appreciates water but not chronic waterlogging.
The common mistake
Regularly cutting suckers to 'thicken' the tree: each cut stimulates 10 new suckers, creating a tangle that's hard to manage.
The pro's trick
Plant away from pipes and foundations (invasive roots).
Care
Exposure
White poplar requires full sun exposure to develop well and encourage vigorous growth. It tolerates exposed, windy positions. Choose a clear location away from buildings where it can flourish freely.
Watering
This tree has significant water requirements, particularly when young and during dry periods. Water regularly for the first three years after planting to establish a solid root system. Once established, it exploits deep reserves, but appreciates fresh soil.
Soil and planting
White poplar adapts to all soil types but prefers fresh to moist, even slightly clayey soil. It tolerates chalky and compacted soils well. Plant preferably in autumn or early spring, in an area where it has sufficient space.
Pruning and maintenance
Intervene on white poplar in the very first years to shape its structure and remove weak or crossing branches. Prune in late autumn or late winter, outside the sap flow period. Once the tree is established, keep maintenance to a minimum.
Fertilizer
White poplar grows vigorously without specific fertilizer thanks to its adaptability. A mulch rich in organic matter at the base during planting is usually sufficient to feed the young plant.
Pests and diseases
White poplar can be susceptible to cankers, rust, and poplar leaf rust in humid conditions. Ensure good air circulation and avoid stagnant moisture in compacted soil. Remove dead or diseased branches as soon as they appear.
Did you know?
White poplar, also called 'trembling aspen', is a tree highly valued by ecologists for its ability to rapidly colonize disturbed and degraded land. In the Mediterranean and Central Asia, its bicoloured leaves (green on the upper surface, white on the reverse) flutter at the slightest breeze, creating a distinctive luminous spectacle that has inspired many poets and painters.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
