I've been all over the internet looking for a match for this invasive "grass" that's infiltrated my lawn. This past Spring, I went to a local lawn care retailer to buy some professional grade fert and weed killer. I'm tired of the Scott's 4 step plan as the only option from HomeDepot/Lowe's/etc. and since I have about 40,000 sq. ft. of lawn, I wanted something more cost effective.
The place I went to sells to homeowner's, but also outfits a lot of local professional people as well. Also, my local Penn State Ag Extension office recommended them.
Anyway, I have about 15000sq. ft section of lawn that was started to get invaded by this "grass". The place I bought my material from said to over-seed with a slit-seeder first, to try to establish more grass; then next spring, hit it hard with 2,4-D and kill off the weeds in the pre-emergence phase.
Unfortunately, our weather didn't cooperate. I slit seeded everything in late April and temps were kind of low. Soil temps never really got up and going until late May and then summer hit. In summer time, this "grass" finally takes hold and proliferates like mad. Here are a few pictures.
This one shows the grass tall, uncut. This stuff has spread over half my yard. I try to keep the wooded edges of my property cut, but some areas go uncut...and this is what it looks like at roughly 12-16 inches tall. The bottom two pics are cut at mower height of about 3 to 3.5 inches.
Last week, I spread some pelletized 2,4-D and it doesn't seem too be affected at this stage. I've seen this stuff growing in dense shade, full sun...everywhere...doesn't seem to matter. Any thoughts or ideas are very much welcomed.
