AM desperate to find out how to eradicate ivy that has overtaken
my shrubbery. We have sprayed with Woody Weedkiller (not much success)
and Network. Can you please help me before I go nuts?
weedkillers like Roundup, Glyphosate and the Network you used can
eventually kill off ivy, but it takes some time for them to work
and you often have to apply them several times.
A Native Forest Restoration
Guide, published several years ago, contains suggestions for controlling
ivy. With glyphosate it recommends you use 150ml of Roundup or Glyphosate
(360 strength) in 5 litres of water. It also lists Activated Amitrole
for ivy control and again suggests a strong rate, 100ml Activated
Amitrole in 5 litres of water. Add a wetting/sticking agent like
Sprayfix, Pulse or Spraymate to the solution for better uptake and
make sure to get good spray coverage of as much of the ivy foliage
as possible. It may be two to three months - or more - before the
ivy has finally died off. Be sure to avoid getting spray on any
