TO KILL WILLOWS
Be aware that
Willows will grow from any piece that is left on the ground (or
allowed to float downstream), so killing the Willow first is of
prime importance. That way, anything that breaks off or is chopped
down for disposal will be dead and won't re-grow.
a cordless drill (9mm bit)
holes around the base of the tree, into the sapwood, angled
down at 45 degrees and at 5 cm intervals.
the holes about 40 cm deep
a few seconds of drilling each hole, fill it with herbicide
upon the size of the Willow, you can also spray the leaves,
or use the "Cut and Paint" method, but you will have
to be very careful about how you dispose of the cut pieces (burning
preferably - don't put them in with green waste or shred them).
and Paint method:

using secateurs, loppers
or a saw. Make sure there is no soil on the cut.

in aquatic areas).
follow instructions and safety precautions to the letter!
