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.
The species of grass seed you sow will help to determine when to expect germination. Ryegrass is the quickest species of grass to germinate. In the correct conditions, ryegrass can germinate in 5-7 days, usually 10-14 days if it is not too cold (see above!).Tall, chewings and creeping fescues are the next species to germinate, usually 14-21 days.he grass seed will germinate in the cup after 10-14 days. If it worked in this experiment you have to figure out why it did not grow on your lawn. You need to determine why it failed, read this article again, and do not always blame the grass seed.
