Even if you use the best rated grass seed on the market, you will want to do some research beforehand. For example, the climate and location of the grass may cause fluctuations in the length of time grass seed will take to grow.
Grass seeds germinate at different rates, which makes determining the length of time it takes to grow differ depending on the various factors. However, as an approximation, it takes grass seed at least 10 days to begin to grow and it will then grow at a rate 2 or 3 centimetres a week. This type of growth is dependent upon certain factors as discussed below.

Type of Grass Seed
Unfortunately the UK doesn’t benefit from a warm climate all year round, which makes the types of grass seed limited. By far the most common seeds in the UK is perennial ryegrass and this is due to the fact they only require up to 10 degrees to consistently germinate. As long as you plant the seeds at the right time, this type of grass seed will grow fast.
Another popular grass seed that grows fast in the UK is fescue but they require over 10 degrees to germinate consistently, which may only be achievable in the summer time.
Preparation of the Ground
Preparation is key to the success of growing grass and it’s a major factor in how long grass seed takes to grow. The seedbed should have all moss removed, as well as any weeds and also be level. Before you plant the seeds, it’s highly recommended to keep the soil moist. Therefore, watering the soil (if it isn’t raining) a few days before on a daily basis is advised for the perfecting growing environment.
Time of Year
As briefly mentioned above, the ideal temperature for grass seed to grow quickly is around 10 degrees. Therefore, in the UK, we usually achieve these temperatures from March to September. If possible, we highly recommend looking at a two-week forecast as an indication of the best time to plant grass seeds.
Aftercare of the Lawn
In order to speed up the time it takes grass seed to grow, aftercare is very important. You will want to use a garden hose or even better a garden sprinkler to water your lawn once a day unless it rains. For the first few weeks, you will want to deeply water the seedbed to reduce the time the grass seeds take to grow. However, it’s crucial that you don’t drown the seeds by overwatering them as this will cause issues.
Although grass seed may take 10 days to grow, you will only be able to achieve this by meeting the optimum growing conditions as stated above. Watering the soil to keep it moist and planting your seeds in the spring or autumn when the temperature is around 10 degrees are the main factors to consider. However, a high quality seed mix and following the instructions stated by the manufacturer are just as important.
