Default Weed killers

Got a patch of land to clear on clifftop prior to sowing with wildflowers.
At the moment it has some dockens and lots of hogweed. We have stuff for
the dockens but not sure of the hogweed. We have roundup but would like to
keep the grasses growing to hold the soil surface together. Past years we
have just cut the hogweed down with a strimmer but been burnt that many
times I would like to clear them for good.
swap male for mail


Treatment with Glyphosate is the recommended way to clear Hogweed. The
problem is that the plants will have produced thousands of seeds which will
germinate for several seasons. If you can slice through the root structure
underground then you will dampen the plants ardour but they will resprout
with fresh young growth fairly quickly. If you hit this young growth with
Glyphosate the plant will eventually die.
Don't be too impatient because it may take several weeks before you notice
any effect.
A more labour intensive but perhaps quicker solution is to pump weedkiller
directly into the stem at various heights by use of a syringe.

ps. I actually grow this beast as an ornamental plant --just one:-)
