seeding directly into crabgrass
I seeded 2 by 2 foot squares with Pennington Sun and Shade seed, 64 percent rye. Sept 6th. I sowed one ounce of seed, 3 ounces of seed, and one ounce after aerating. The area was heavily infested with crabgrass, but not totally bad because of recent light rains. There was no irrigation nor soil preparation.
It turned out to be near a bus stop and kids damaged a couple of my markers.
It is difficult to determine the percentage of seed success, but some seed arose in all of the treatments. Top picture had 1 ounce of seed. Bottom picture had 3 ounces of seed. The new grass has a thin blade and is lighter green. The treatment with triple seed seemed to look slightly better. More results later. Temps have been about 65 days and 50 nights. Very light rain in last few days.
No photo for the area that was aerated first--sorry--seed was also arising in this area.
