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.
While it may not be properly grown yet the visible result may take about two to three weeks. The normal duration at which the seed of the grass germinates is between 6 to 10 days after the seed has been planted. However it can also take from minimum 4 days to maximum forty days. The climate condition during which the seed is sown is also very essential for the seeds to germinate faster and to grow. If the seeds are sown during mid spring the results may show by the summer.
