Some growing experimental condition are so ideal that sure species of fern can outgrow the garden , taking over significant sections of yards and woodlands . chemic weed killer are an of import part of see to it trespassing ferns .

Significance

There are many species of exotic ferns that have been introduced to garden .

Boston fern ( Nephrolepis exaltata ) can become naturalized in USDA zones 9 and quick . In Florida , the Old World climbing fern ( Lygodium microphyllum ) and the Nipponese mounting fern ( Lygodium japonicum ) both become invasive , climbing up structures and woodland trees .

Mechanical Controls

winner in annihilate invasive ferns by mechanical removal of plant is unelaborated . However , it is worth a try in controlling small domain of fern in the home landscape painting . Yank ferns out of the primer coat , doing your best to remove as much of the rhizome as possible . Mulching after removal will help keep spore from germinating in the area .

Herbicide

Apply in outflow and other summer when fern are actively growing . forfend getting glyphosate on suitable plant , which will be damage or killed by the chemical substance .

It may take several applications of glyphosate to kill ferns to their ascendent . Reapply as the plants die down and new shoots arise . rive raw ferns that sprout from spore in the curtilage or garden . scrutinize the area the keep up spring and apply the weed killer if necessary . Planting cleared region with native plant , well adapted to the local environment , will serve control alien fern in the future .
