How Long Does Grass Seed Take To Grow & Germinate

Last Updated on May 20, 2022 by Real Men Sow

The rate at which grass seed germinates depends on many factors, including the grass species, weather conditions, soil moisture, and time of year.

How Long Does Grass Seed Take To Grow

Grass seed germination typically takes between 5-10 days. The grass will continue growing at about 2/3cm per day once it is germinated. Below are some factors that affect grass seed germination. We also offer tips for how to make sure your lawn is perfect.

Grass Seed Germination In Hot & Cold Weathers

The germination rate for grass seed depends on the time of year. Germination is prevented by cold temperatures and low soil temperatures. This is why you should avoid sowing grass seed in winter. Cold springs can slow down the germination process by up to two weeks. This leaves the seed open to being eaten by birds or blown away.

Hot summers can also hinder growth, especially if the soil is dry. For successful germination, the soil temperature must be at least 8°C. Seed sown in Scotland’s south will germinate faster than those sown there. It’s best that you sow grass seed in the middle of spring and again in the early autumn.

Moisture Of The Soil For Grass Seed Germination

The soil should be moist, but not too dry or wet. Grass seeds germinate well in moist soil. To aid in germination, keep the soil moist. However, you should spray the soil with a fine rose to prevent puddles from forming or wash away any seeds.

Grass Species To Grow

Different seed mixtures germinate at different rates. Hardwearing seed mixes, which often contain ryegrass and red fescue, usually germinate in four days. Some seeds, such as bent and meadowgrasses, may take up to two weeks to germinate.

5 Tips To Succeed With Grass Seed Germination

  • You should keep the soil moist but not overwater it.
  • When the soil temperature is at least 8°C, sow seeds in spring and autumn
  • Do not allow the soil to dry until you see dense green growth growing from the area where you have sown the seed.
  • Follow the instructions on the packet to determine how dense you should sow your seed.
  • Avoid sowing when it is windy as this can blow grass seed around
