1. Enhance Structural Integrity
Weeping willows develop rapidly, placing on about three to 4 toes every year, till they attain maturity, which takes about 20 years.

2. Remove Crossing and Cut back Density
As a weeping willow sapling grows, many branches sprout to kind a dense cover.
Some cross over one another, rubbing and opening the outer cambium layer, rendering the wooden beneath weak to breakage and the ingress of pathogens and pests.

It creates well-sealed “knuckles” that stop moisture from penetrating and rotting the trunk.
When younger timber – 15 years of age or much less – are pollarded, the brand new development is eliminated to the knuckle yearly. They regrow rapidly.
For mature specimens, pollarding ought to happen each three to 5 years as a result of regeneration is gradual.
The method permits gardeners to attenuate undesirable encroachment over sidewalks and roads, create a smaller shade-casting cover in house landscapes, and preserve a constant, manageable top and width.
