white poplar

White poplar should be watered on a regular basis throughout the growing season, typically about every 5-7 days. During the hottest summer months, water every 3-5 days. Make sure to water thoroughly, giving the plant a deep, slow watering until the soil is thoroughly saturated. Allow the soil to nearly dry out before watering again. Water in the morning to give the foliage time to dry out and warm up quickly to reduce the risk of disease. In the winter months, white poplars should be watered less often as they go dormant, usually only when the soil feels dry.

The white poplar, also known as Populus alba, thrives best when it receives around 5-6 hours of sunlight each day. As a light-loving species, the white poplar performs best when it gets the full morning sun and partial afternoon sun. A lighter shade for the remainder of the day is ideal for this species of plant. To provide the best results, place the white poplar in an area that receives the morning sun and partial afternoon sun from 10am-3pm daily.

White Poplar should be pruned in late winter or early spring. It responds well to regular pruning, so prune lightly every year or 2. If the stem growth is excessive, such as more than 12 inches in length, a heavier pruning can be done every 3 to 4 years. Remove branch tips and any crossing or rubbing branches, as well as dead, diseased, or overly long branches. Also, thin out interior stems to open up the canopy and encourage more vigorous growth. Prune just above a bud or branch node, but avoid cutting back too far into the center of the tree.
