Invasive Plants of the NorthEast Removal and Management
Invasive plant removal is tedious and time consuming but worth it when you see the native wildlife enjoying their native habitat and the beauty of the now sparse native foliage. Its necessary to plant native plants immediately following the removal of the invasive plants to hold back the invasive plants. Plant native grass, wildflower, and native shrubs and pioneer species of trees so that they grow rapidly helping limit the sun from the ground foliage and potential of invasive plants taking root first. First to grow is first to establish.
Develop a Tree Canopy with Pioneer Species Trees
Manage the area until a tree canopy is developed, or native meadow. If manual removal is not feasible, weed whack before the invasive can produce berries to limit its spread.
Native Berrying shrubs to have nature help battle back
Have native berrying shrubs and encourage their growth until the native develops berries. Caging prevents deer from instantly eating the native before it berries. Exponential speed of growth and berry production which helps get your area filled with bird spread native shrubs eaten from your site.
Remember to propagate Native with Live Stakes
When the deer rip up your native shrubs, voles eat your sycamores, or you just want to spread your natives from your garden or nursery, remember many native plants can regrow from a stem, branch, or whole section of the tree or shrub. Just replant or jam it back in the ground in a moist area.
Knotweed
Invasive plant profile: Knotweed
Growth: Takes over, constantly tries to expand, but you can hold a line Manually pulling if monthly monitored
Ways to remove: Herbicide Horrible.
If sparse and new you may manually remove.
If Knot weed is established follow
Penn State Extension Herbicide Recommendations:
Cut in June
Herbicide 8 weeks later
2 years in a row
Observations:
River Birch can be planted after first year's herbicide application.
4 foot Gray Birch planted within an established area after manually removing without died shortly after planting, it did not come out of dormancy

Mile a Minute
Invasive plant profile: Mile-A-Minute
Growth: rapid growth, especially in the July
Thorns, Triangular leaf, reroots periodically
Ways to remove: Manual or Herbicide
Manual removal-
Wear gloves and long sleeves because of the thorns
Gently pull at the base near soil to remove with root intact
Remove before berries product in July

Porcelain Berry Vine
Porcelain Berry
Invasive plant profile: Porcelain Berry
Month producing berries: July
Growth:
rapid growth, especially in the July
Establishes a root system underground which will need to be pulled up.
Grows a blanket of foliage over top every other plant in the area including all the way up trees which with take down old growth trees by starving the tree (and every other plant of sunlight.)
Ways to remove: Manual or Herbicide
Manual removal-
Try to pull up the whole larger root system below while preserving native growth
Remove before berries produce in July
Weed whack if you cannot pull it all
