rid of pesky plants
Chinese toon is spreading like bamboo; I need to kill it. It's too
tall to spray the leaves; I thought of cutting the trunks a few
feet from the ground, drilling deep holes down the centre of the
trunk and keep filling it up with some sort of poison until it dies.
Any ideas would be helpful.
only things I tend to spray are my roses, so I asked Reg Lewthwaite
(one of our Horticulural Science lecturers and also a GROWSAFE trainer)
what he thought about your problem. Reg suggested that the best
way was to cut off the trunks and immediately apply a herbicide
to the cut area. If you have glyphosate at home use it by diluting
it a little in water and brushing it onto the wound. There is a
new product on the market in a special applicator that keeps the
agrichemical from drifting onto other plants. It's name is Vigilant
and contains a chemical called picloran. Of course we recommend
you use extreme care when using any type of spray always
read and follow the instructions.
have a number of agapanthus to get rid of. In the main I am digging
them out, but there are some that are growing in cracks in mowing
strips etc that I cannot get to the root base of. Is there a weed
killer that works effectively on agapanthus?
another question where I must seek help from Reg Lewthwaite (Lecturer
in Horticultural Science and GROWSAFE trainer). Reg says: When it's
impossible to dig out roots of plants without damaging the footpath,
or where you can't get at them to dig them out, there is often no
real alternative to a herbicide. The best herbicide for agapanthus
is one containing triclopyr. There are two main products containing
this chemical. They are Grazon and Tordon Brushkiller. You need
to apply the agrichemical to the leaves and it may take some time
to kill the plant. You could also try a new product called Vigilant
it is in a special applicator that keeps the agrichemical
from drifting onto other plants. Good luck.
