Cat tails control

Asked April 16, 2015, 8:32 PM EDT

I have a wetlands at the edge of my yard with cattails which have been gradually encroaching my lawn. Is there a way to curb, control, discourage their advance?

Mowing the cattails after the heads are well formed but not mature, with a follow-up mowing a month later, can deplete the plants and cause them to die. Plants invest a great deal of energy creating their seed heads and are less likely to produce vigorous growth after the first mowing. One thing to bear in mind is cattails spread by seeding and will continue to encroach into your lawn as long as conditions are favorable. They prefer full sun and wet soil, but can tolerate short periods of drought. Make sure the soil in your yard is well drained and your grass is cut to between 1.5 and 3 inches so it shades out the cattail seeds.
