Hi David and everyone,
Given Fred's information that Miscanthus giganteus is sterile and spreads
only slowly be rhizomes then mowing should be a fairly effective control
which further makes it a good target species to test carefully for biomass
suitability in Nova Scotia. I say test carefully because there are certainly
cases of supposed sterile garden plants that suddenly become quite fertile
as if by magic. Sometimes profit has a nasty way of making people overlook
unexpected behavior until it's too late.
For the Eurasian subspecies of Phragmites that is firmly entrenched along
roadsides in the Montreal area, I've seen no suggestion that mowing does
anything except prevent the growth of small trees and shrubs that precede
the succession to a woodland. The stands usually get cut twice a summer and
they are showing no signs of diminishing. Repeated burning appears to do
the trick. I've seen burning used at one of the local DU marshes and one
season of burning did have some effect.
All the best,
Lance

Hi Lance & All, June 29, 2012
Phragmites acts as a very effective trap for wind blown seeds such as
Ash, Maple and no doubt conifers if there were trees within wind reach.
Phragmites may well become a monoculture if it is growing where nothing else
can but on other than marsh/swamp soils it will quickly become woodland if
there are forest trees nearby. Mowing the perimeter twice a year, with a
scythe, during the growing season prevents spread of Phragmites by rhizomes.
Miscanthus would be planted on upland soils that can be mowed by machine
in the spring so spreading off of the field should not be a problem,
especially if there were a mowed perimeter (in the summer) where spreading
seems to be a potential threat.
Yt, Dave Webster, Kentville
