yes and it roundup acts systemicly so ther is very little leeching into the
soil.( I don't belive *none*

Yes this seems correct as I have been taught, also by leaving the leaves or
not cutting you give more area to asobrb so more end result is accheived. I
like this Ivory sopa idea... when I sprayed my ivy with triple strength it
just *watered it* from what I could tell and probably terrible for the
environment

more isn't better but if you read the active ingrediants you will see there
are about 3 different blends of roundup--it isn't labeled triple
strength...

Totally agree here.

hmm I would be really careful here, if you love your plant it may die anyway .
NEVER spray on a windy day.
also I always wear throwaway gloves and at least a painters mask. at the
minimum i get a headache otherwise and who knows about long term effects.
