Phragmites, also known as common reed, is an invasive,
non-native plant that grows in and around wetlands,
marshes, rivers, lakes, and ponds. This aggressive
perennial grass wreaks havoc on our ecosystems,
choking out native plants that support pollinators and
other local wildlife. If left unchecked, phragmites can
change habitats, lead to loss of biodiversity, and
negatively impact the overall ecosystem.
HOW TO CUT
Using hand shears, cut the
stems down to 6-12 inches in
height, below the lowest leaves.
If you cannot reach the lower
stalk, focus on cutting the seed
heads as this will prevent
further spread. Collect cuttings
and bag them.

How can phragmites be controlled?
Phragmites removal and management is a long-term
maintenance effort. Thanks to a grant from the Long
Island Sound Study, National Fish and Wildlife Service,
and support from the Town of Southold, Group for the
East End, and Kenney’s/McCabe’s Beach Civic
Association, Great Pond residents are continuing
efforts to remove phragmites by hand and by hydro-
rake. Hydro-raking removes plants and root systems
from the water, and offers a chemical-free solution.
MANAGING PHRAGMITES
WHEN TO CUT
Optimal time to hand-cut
phragmites is in late July and
August, before full bloom. A late
fall cut is also useful to
continually weaken the stands.
Cutting should take place twice
each year as part of an annual
landscape management plan.
HOW TO DISPOSE
Southold Town will accept
bagged cuttings at the transfer
station. DO NOT COMPOST!
Composting will encourage the
spread of phragmites.

Re-vegetate the areas where phragmites have been cut with native and Long Island ecotype
plants, which are plants that have evolved to thrive in our local conditions. If possible, plant
mature plants ( 2 - 5 gallon size)as they can compete better with phragmites than plugs.
