The germination time for grass seed ranges from 5 to 30 days depending on the variety. It can be even longer than this in cooler temperatures. This is how long it will take to actually see the grass growing. Until this point, the seed, or the soil and mulch in contact with the seed, must stay moist.
1 One to five weeks after the grass seeds germinate, the mycelium, or vegetative filaments of the fungus, migrate to the lower part of the stem. 2  Once excreted, the fungal mycelium [the mass of hyphae emanating from the fungus] grows into tiny spheres, about the size of a small pinhead.xample sentences. 1  One to five weeks after the grass seeds germinate, the mycelium, or vegetative filaments of the fungus, migrate to the lower part of the stem. 2  Once excreted, the fungal mycelium [the mass of hyphae emanating from the fungus] grows into tiny spheres, about the size of a small pinhead.
