Chinese Necklace Poplar Populus lasiocarpa
ABOUT
The Chinese necklace poplar is a visually striking tree known for its deeply lobed leaves that resemble a classic maple leaf with serrated edges. These leaves grow out dramatically, giving the tree a lush and dense foliage that comes to life with a vibrant green hue during the growing season. As the seasons change, so do the colors of the leaves, transitioning to a rich array of yellows and golds that herald the arrival of autumn. The bark of the Chinese necklace poplar is another notable feature, offering a textured surface that can range from gray to white, sometimes appearing with dark fissures that add to its rugged appearance. Not often mentioned are the flowers it bears; these emerge in long catkins that dangle elegantly from the branches, usually showing up in the spring and adding to the decorative appeal of the tree. Overall, the Chinese necklace poplar has a hearty and robust presence with an ornamental quality emphasized by its fluttering leaves and striking bark patterns.

WaterThe Chinese poplar requires regular watering to maintain moist soil, particularly during dry periods, as it has a moderate to high water demand. Water young trees with 15-20 gallons once a week, tapering off as the tree matures but increasing the amount during extended dry spells. During the growing season, mature trees benefit from deep watering every two to three weeks. It is crucial not to over-water, as standing water or soggy soil can lead to root rot. Adjust the schedule according to rainfall, reducing watering when natural precipitation provides sufficient moisture.
LightThe Chinese poplar thrives in full sun, with at least six hours of direct, unfiltered sunlight per day. It's best planted in a spot that receives ample morning and afternoon sun, ensuring vibrant growth and health of the tree. Avoid shaded areas as a lack of light can weaken the Chinese poplar, making it prone to pests and diseases.
TemperatureThe Chinese poplar does well in a range of temperatures and is hardy in USDA zones 5 through 8. It can survive minimum temperatures of -20 to -10 degrees Fahrenheit for zone 5, but the ideal growing conditions would be where temperatures are consistently above freezing. Maximum temperatures should not exceed 100 degrees Fahrenheit, as extreme heat may stress the plant. During hot summer months, adequate watering is essential to prevent heat stress.
PruningPrune the Chinese poplar in late winter or early spring before new growth begins to remove damaged or diseased branches and help maintain the desired shape and structural integrity. Pruning can also stimulate growth in sparse areas of the tree. It's generally advisable to prune these trees every three to five years, but they can tolerate more frequent pruning if necessary. Always use sharp, clean tools to make clean cuts.
CleaningNot needed
SoilThe Chinese Poplar (Populus lasiocarpa) thrives in moist, well-draining soil with a mixture of loam and sand, ensuring adequate aeration. The ideal pH for the soil should be slightly acidic to neutral, ranging from 6.0 to 7.0.
RepottingThe Chinese Poplar does not typically require frequent repotting as it grows best outdoors with ample space. It is usually repotted or transplanted only when necessary due to restricted growth or soil degradation, often in the range of several years apart.
Humidity & MistingThe Chinese Poplar prefers outdoor conditions where the humidity is naturally regulated by the environment, without the need for specific humidity adjustments.

Life cyclePopulus lasiocarpa, commonly known as the Chinese Aspen, begins its life cycle as a seed which germinates in spring given suitable moist conditions. After germination, the seedling emerges and grows into a young sapling, going through a rapid growth phase where it establishes its roots and a woody stem. The Chinese Aspen then matures into an adult tree, characterized by its heart-shaped leaves and erect stature, commonly reaching heights of 30 meters or more. During its reproductive phase, it produces catkins which, after pollination, develop into capsules that release numerous seeds, typically dispersed by wind. The tree has a deciduous habit, shedding its leaves in the fall, and entering dormancy during the cold winter months. With an ability to reproduce both sexually, through seeds, and asexually, via suckers, the Chinese Aspen can form clonal colonies that may live for several decades.
PropogationPropogation time
Spring-Early Summer
Propogation: Populus lasiocarpa, commonly known as the Chinese necklace poplar, is generally propagated through hardwood cuttings. The best time to take these cuttings is during late winter or early spring when the tree is still dormant but the ground has thawed enough for planting. To propagate by this method, select a healthy, mature branch and cut a section about 6 to 8 inches (15 to 20 centimeters) long, making sure it has several buds. The bottom cut should be made just below a bud, and the top cut should be made about half an inch (1.27 centimeters) above a bud to ensure proper growth. The cuttings should then be planted in moist soil with about two-thirds of their length buried. Roots and shoots generally begin to develop in the spring, though it may sometimes take until the next season for growth to be noticeable.
