|This is a shady area that used to be mowed. The stilt grass has moved into |
the gaps and is crowding out the native vegetation.
- Pull in early August. This allows a second crop to germinate, but not enough time to mature before frost.
- In natural areas minimize disturbance to soil and encourage existing native species. Cut stiltgrass low when flowering starts, about mid to late August to early September.
- In disturbed areas (lawn) try to add more competitive ground covers, like cool season grasses to get established before stiltgrass germinates in mid-April (WVa).
|Japanese stiltgrass is turning brown in the lawn early October. |
This thatch can be slow to break down,
leaving a gap for more to germinate in spring.
|Here's that same shady area after weed whacking and raking up the cut stiltgrass (upper left). |

|Since each fescue plant is so small the seeding rate|
is fairly high, 5 lb/1000sf, to get good coverage.
For sowing, I first used an iron rake to clear out the stiltgrass thatch. (Looking back, if had done this in early September I could have limited the stiltgrass seed production even more.) This also loosened the soil surface. Then I broadcasted the seed. Finally I used the flat edge of the rake to push the seed in closer contact with the soil. To get good germination and establishment of the seedlings the ground should be kept moist. I usually try to time fall seeding with the weather forecast to take advantage of rainfall to get the grass started.
|About 10 days after seeding with Eco Grass a fine green haze is covering this previously barren area.|

A better way to sow these native grass seed would be to use a seed drill and put them in 1/4 to 1/2 inch deep. Instead, I sowed them the same as I did for the fine fescue, but at a much lower rate (pounds/sf). The recommended rate for Eco Grass is 5 lbs/1,000 sf while for Canada rye it is on the order of 3 oz/1,000 sf. Since the ryes and other native grasses are much larger plants when mature, compared to a single fescue plant, it takes only a few seeds to get the same coverage.
|June grass has a seed similar fescue is size; |
however, the resulting plant is much larger
|Side oats grama has a lot of husks included, but|
these are accounted for in the PLS calculation
|Virginia and Canada ryes look similar.|
|15 days after seeding I'm seeing some new grass growth in some of the sunnier areas. |
The shade areas are not showing definitive signs of new grasses.
|We were surprised to find this obedient plant |
blooming late in the season. I don't know if this is indigenous
or if it escaped from an earlier planting by a previous landowner.
