It is important to remove the roots of Invasive Honeysuckles.

Clipping:
Repeated clipping of invasive honeysuckles
over a prolonged period of time (3-5 years) can
effectively control infestations. Clipping should
not be done in the winter, as this will cause
extensive re-sprouting in the spring.
Cutting:
Larger stems can be cut using hand tools,
chainsaws or brushcutters. Keep in mind that
cut stumps will re-sprout quite vigorously in the
spring, and therefore, this control method is
often followed by an application of a herbicide.
Stumps should be cut sharp and straight across,
particularly when followed up with chemical
control.
In a 2010 study, Amur honeysuckle was removed
mechanically with a chainsaw and hand clippers.
By the following spring the cleared area had a
lush regrowth of Amur Honeysuckle from stump
sprouts, new subterranean shoots and emerging
seedlings. Another invasive plant Common
Chickweed (Stellaria media) had also colonized
the area.

The following year (May 2011) an area was cleared
of Amur honeysuckle and other woody invaders
using hand clippers and chain saws, followed by a
herbicide application to the cut stumps. By mid-
July, this method had proven more effective than
using only manual removal.
