Hello- We first noticed Wild Cucumber vines in our swamp/marsh land late last August. The blooms were quite visible- and too late to adequately remove. The vines took down cattails and reeds in a specific area. They appear to not have returned strongly this year- and the area is replaced with grasses. I notice the vine has returned this year (!)- not yet in bloom. Should I be concerned that it will invade the entire marsh- taking down more cat tails and reeds? What steps should I take to remove or care for the marsh and wetland- if any? Thank you for the help-
