A few veronica weeds have sprouted in the sod. Now cool; temp today is 44. Crabgrass is collapsing and lawn grass and a bit of tall fescue are recovering.
In lower photo, seed (Ace, high in perennial rye), was applied in 7 inch circles on top of crabgrass, with no soil preparation nor irrigation. The two circular areas on the right were sown with about 20 times the recommended amount of seed. The four circles to the left had about 4 times the proper amount of seed. The area is about 5 feet from the sod and about 20 feet from a bird feeder that is visited by many sparrows.
This proves what I know about Rye grasses (all). It takes way more seed than label recommended to get good results.
