Description of pyramidal poplar
This slender tree with a narrow-columnar crown can reach over 30 meters in height, and the crown diameter is up to 6 meters. The maximum lifespan is about 300 years. It is also valued for its rapid growth, which is important when landscaping a city. In the photo of a pyramidal poplar, you can see how unusual and beautiful the extended crown of a dark green color looks.

The leaves of this type of poplar are medium-sized, can be triangular or in the form of a rhombus. In autumn they acquire a golden yellow color. They begin to fall off at the end of October.
Poplars bloom in March-April with catkins in which small inflorescences are collected. Males are up to 8 cm long and purple in color, females – up to 15 cm and yellow stigmas with a spherical green ovary
Fruits ripen in early June, which are egg-shaped capsules containing many small seeds. More often, males are used for planting, since they do not produce fluff, which can cause allergies in humans.
The root system of this poplar is highly developed, but at the same time some of the long roots may be on the surface.
Bees collect a sticky substance from this type of poplar, which is then processed into propolis
Average frost resistance. Calmly withstands temperatures down to -28 degrees. The best places are places where there is weak snow accumulation in winter and there is a possibility of freezing the soil so that it does not become podoprevat.
Subtleties in caring for a pyramidal poplar
Due to the root system, you need to carefully choose a planting site, since after 50 years it can destroy the asphalt and damage the foundation. Therefore, it is not recommended to plant this tree near roads and buildings. The distance from the poplar to them should not be less than 50 meters.
It is better to plant cuttings with several live buds in spring or autumn:
- Dig a hole 1 meter deep.
- Make a drain below and install a seedling.
- Sprinkle with earth so that the root collar is buried no deeper than 2 cm.
- Tie to a support for greater stability.
You need to water every 2 weeks with 25 liters of water under each tree. For the first 5 years, it is advisable to loosen the soil, which will contribute to faster growth.
If affected by fungal diseases or pests, treat with insecticides.
Poplar loves light, which makes it possible to plant it in open sunny areas. It can be seen from the description that the pyramidal poplar is well suited for growing green walls, creating alleys and landscaping the city, as it grows quickly, cleans the air from harmful emissions around the clock and helps to suppress noise. Also, males do not produce fluff, which can harm humans.
