Q: I planted seed three weeks ago. The grass has come up nicely but there are some tall sprouts that are twice as big as the rest of the grass. What are they?

A: Did you use wheat straw to mulch your newly planted lawn? If you did, the wheat seeds in the straw have sprouted alongside the fescue seed. The wheat is not a problem; you can mow it down when you mow your lawn. Next summer it will die when hot weather arrives again.
