How to treat the phenomenon that willow trees used for greening every year lead to catkins flying all over the sky?

Willow is a very beautiful tree species. ..... willow branches swaying in the wind, very beautiful.

Because of this, willow, as a greening and ornamental tree species, is planted in many places. ..... The graceful posture of the willows also adds more charm to the surrounding beautiful scenery.

However, the willow itself is a defective tree.

Specifically, the defects of willow have the following aspects:

1, catkin.

Every spring, willows begin to float catkins.

Catkin flying all over the sky not only affects the line of sight, but also forms catkin clouds on the ground, affecting the local scenery. Catkin floating in the air can also make people sneeze and feel uncomfortable.

So many people don't like catkins very much. ..... This is catkin.

2. Rapid growth.

Willow grows very fast, and it can grow to more than 10 meters in ten years.

Moreover, wicker grows faster and needs to be pruned frequently. ..... This makes the workload of daily pruning and maintenance increase a lot.

3. Short service life.

Willow's life span is very short, and it will obviously age at the age of 30.

Therefore, as a green tree species and ornamental tree species, willow needs to be replanted regularly, and the cost is relatively high.

Among the above defects, catkin has the greatest influence on people.

Therefore, the problem of willow as a greening tree species is not too big, but as an ornamental tree species, every spring when catkins fly, it will make tourists feel uncomfortable.

Therefore, in some places, other trees have been used instead of willow as ornamental trees.
