Removing a Willow Tree?

Hello !
That is right not every willow will grow again after being cut because there are different types of willows and trees are just like humans. An old and big willow will not recover and will not grow again as rapidly as a young one. Willows do not live long anyway. The white willow: Salix viminalis lives only 30 years and Salix caprea only 50 years which is a quite short life for a tree.

If you buy a house with a 30 years old willow in the garden you don't have to worry about the damage the willow can do to water pipes because at this age it has already reached its full growth and will not do more damage than it has already done. New shoots from a cut down willow start from the bark or the roots but not from deeper in the stump than only the bark thickness and if the willow is very old and its bark is very thick and very hard, it will not be possible for the new shoots to appear on the stump. That is why one way to avoid the regrowth of a willow from a stump is to chop off the bark. An old tree also creates a microclimate with, for example, the shadow the branches makes around the foot of the tree, and when suddenly the foot and the superficial roots are back in full sun because the willow was cut down it can dry out the soil and stop the tree producing new shoots, especially a willow which depends so much on water supply in its early years.
