its no biggy..!
I have done this method with hedglings not weed
it should work for weed
I prefer to use a rapid rooters
open it up sandpaper the area to expose the cambium
wrap the rooter around the stem,
then wrap kitchen foil around that
like the hillbilly above keep them damp
done and dusted in 12 days, weather dependent
the advantage of the rooter is they are light and can put many on one plant
apply honey to the exposed stem first
good luck
