Alder Alnus glutinosa
Alder grow in
damp areas. Although an attractive tree they are very prolific and disperse seed
in vast quantities. They are well adapted to take advantage of cleared and newly
planted areas.
Control:
Drill a series of ten
mm holes in the trunk and fill with glyphosate herbicide, ringbark and paint
herbicide on the cuts or cut down and remove the whole tree. If the dead tree is
to be left standing, remove the lower branches to allow access to the other
weeds
