- Life cycle
The life cycle of Ulmus pumila begins with a seed. The seed germinates in the spring and produces a small seedling. As the seedling grows, it develops a taproot and a few lateral roots. The leaves are small and simple, and are arranged alternately on the stem.
In the second year of growth, the tree begins to form a trunk and branches. The leaves become larger and the tree grows rapidly. By the third year, the tree reaches its full height and begins to produce flowers. The flowers are small and inconspicuous, but are important for reproduction.
After flowering, the tree produces small winged seeds that are dispersed by the wind. The seeds germinate in the spring and the cycle begins again. Ulmus pumila can live up to 30-50 years. It is a deciduous tree that lose its leaves in the fall and goes dormant in the winter. - Propogation
Propogation time
Spring
By SEEDS:
The most common method is to collect the seeds from mature trees and sow them in a seedbed. The seeds should be sown in the fall and covered with a thin layer of soil. They will germinate in the spring and can be transplanted to their permanent location when they are large enough.
By CUTTINGS:
Another method is to take stem cuttings from the tree in the summer or fall. The cuttings should be taken from mature, healthy branches and be about 6-8 inches long. They should be planted in a well-draining soil mixture and kept in a warm, humid location.
By GRAFTING:
Ulmus pumila can also be propagated by grafting. This method involves taking a cutting from the tree and attaching it to the rootstock of another tree. This is typically done by a professional and is a very precise and demanding method.
By LAYERING:
Layering is another propagation method. It is done by bending a branch of the tree to the ground and covering it with soil. The branch will eventually root and grow into a new tree.
