can wildflower seeds compete with Japanese stiltgrass?

Asked April 25, 2019, 9:22 AM EDT

Hi we live in western Howard County, MD, and have a big infestation of Japanese Stiltgrass in the reforestation area around our house, and it's encroaching into our lawn. I was wondering if wildflower seeds would be able to compete with it? Thanks.

One of the big problems with foreign invasive plants, such as stiltgrass, is that they form monocultures because they are so dense, so many seeds germinate (often about 99%), or they grow taller and shade or smother the native plants.

Tall perennial native flowers should be able to compete once they get established, as they can grow over the stiltgrass. Shorter species will likely succumb.

Here is a good online resource for native options : Native Plants for Wildlife Habitat and Conservation Landscaping: Chesapeake Bay Watershed.


So your best bet may be to plant some potted/containerized plants with some size to them when you put them in the ground to give them a headstart over the stiltgrass. They can then spread more seed.

OK thanks very much for the prompt response
