Determining the flowering time of the birch tree can be just as interesting for nature enthusiasts as it is for gardeners and people with pollen allergies. Once a year, the tree, known to be an extremely resilient species of life, releases large amounts of pollen into the wind to ensure its reproduction. Here you can find out everything about the birch tree in its blooming season.
When is the birch flowering time?
Birch blooms between March and May. During this period, male kittens release large amounts of pollen, which is relevant for allergy sufferers and garden owners. Yellow pollen is a typical phenomenon in birch flowers.
When does the birch tree bloom
The flowering period of the birch tree takes place between the months of March and May. Anyone who is allergic to birch pollen often notices the first symptoms before this classic season. Since the male flowers in which the pollen ripens are formed in the fall of the previous year and then rest over the winter, there can be even the smallest particles of pollen near the trees. In addition, the increasingly mild winters and early, sunny, warm spring days literally invite the light-hungry birches to bloom early.
What happens during the flowering period
The beginning of the flowering period of a birch tree is hard to miss: the distinctive male catkins appear in bright yellow on the older long shoots, while inconspicuous pale green-yellow female catkins can be seen on the short young shoots. The male flowers, which are approximately ten centimeters long, release considerable amounts of pollen into the wind. Because birch trees reproduce exclusively by wind and, rarely, cross-pollination.
For this reason, the flowering of the birch tree is characterized by another, often unpleasant phenomenon: yellow pollen settles on windows, balconies or cars. If you want to plant a young tree in your garden, you should carefully consider the location of the birch tree. Give the tree enough space and, if possible, greater distance:
- own living area including terrace and balcony
- Neighboring property
- other plants
