How Long Does It Take Grass Seed To Germinate (And Why)?

Exact Answer: 7 to 30 days

Grass seed is a horticulture necessity that helps people create beautiful and vibrant green lawns. It is an inexpensive home decor that can be easily grown and maintained. The germination process occurs at different rates depending on numerous factors such as grass species, soil moisture, time, and climate.

Several different species of grass grow in different seasons. Some examples include Bentgrass, Kentucky Bluegrass, Perennial Ryegrass, Zoysia grass, etc. Each grass type has unique requirements and a different planting period.

The methods used to sow grass seeds vary depending on the seasons. Some species require cold temperatures with minimum moisture, whereas some may grow better in warm temperatures. Some species grow only in the absence of light and therefore demand shade at all times

The seeds are to be spread out on the lawn evenly. Lawnmowers can be useful while sowing grass seeds. After plantation, the seeds need the right amount of nutrients and water. Overwatering and the use of too much fertilizer can kill the germinating seeds.

How Long Does It Take Grass Seed To Germinate?

On average, it takes about 5 to 10 days for grass seeds to germinate. For some species, it may also extend up to 30 days. Several factors influence the process of germination, thereby, resulting in different germination rates.

Zoysia Grass Seeds

These grass seeds grow in warm weather, but can also survive in cold weather. Zoysia grows well in unshaded areas and requires less mowing and watering. It takes about 14 to 21 days to germinate.

Red Fescue Grass Seeds

Red Fescue excels in cold weather and requires little water to germinate. It grows well in unshaded areas and can be tolerant to extreme climates and habitats. It takes 12 to 22 days for germination.

Kentucky Blue Grass Seeds

Kentucky Bluegrass is a perennial species of smooth meadow grass. It is a cool-season lawn grass that is tolerant to extreme cold seasons. Its germinating period is 10 to 21 days.

Annual Ryegrass

Annual Ryegrass grows well in warm climates as it is not very tolerant to the cold. It is a versatile grass that grows rapidly. It takes 5 to 10 days to germinate.


This grass is commonly found all over the world. It is a cool-season grass that grows perennially. It takes only up to 14 days to germinate.

Perennial Ryegrass

Perennial Ryegrass or the winter Ryegrass is a bunch forming grass. It grows in the cool season at temperatures between 50°F to 65°F. It takes about 5 to 7 days to germinate.

In summary:

Why Does It Take So Long For Grass Seeds To Germinate?

Grass species, soil moisture, climate, and light play a huge role in the germination period of grass seeds in all seasons. It is recommended to use high-quality seeds to obtain satisfactory growth at a rapid rate. The time of sowing also influences the germination of grass seeds.

Try to avoid sowing in cold seasons to avoid cold air and soil temperature that may prevent germination. Extreme hot temperatures can also delay germination for two or more weeks. The recommended time for sowing is mid-spring or early autumn.

Too much soil moisture can hinder seed germination. Avoid watering grass seeds too and stick to fine rose or sprays to eliminate puddle formation. Dry soil can also prevent early germination, therefore, try to keep the soil moist at all times. If all the factors are taken care of, the seeds germinate at proper seeding duration with no delay.


Grass seeds need less supervision during germination as compared to other plants. There are several species of grass that one may sow on lawns. Some seed grows better in a warm environment, whereas other prefer slightly cold weather to grow.

These seeds take anything between 7 to 30 days to germinate. Some species can germinate within 5 days of sowing if the right measures are applied. Germination gets delayed when important factors such as soil moisture content, temperatures, and light are not provided in the right amount.
