How long does it take grass seed to grow? Different types of grass grow at different speeds and to different heights. Many factors can affect the growth rate of your grass seed, and understanding them is the first step to growing a healthy lawn.

Jonathan Green has worked for more than 100 years to bring beautiful dark-green lawns to our clients using only the highest quality materials. Since 1881, we have experimented with turfgrass varietals to breed our own genetically superior grass seed. We are dedicated to providing clients with the absolute best, so all of our products are rigorously tested to ensure that they perform to the highest standards.

The germination time for most types of grass seed ranges from 5 to 30 days depending on which variety you plant. It can be even longer than this in cooler temperatures.

At Jonathan Green, we mix elite varieties of Kentucky bluegrass seed with tall fescue and perennial ryegrass to create our Black Beauty® Ultra Grass Seed. This seed germinates in 7 – 14 days, as do many of our other grass seed blends.

If this is too slow for you, consider Jonathan Green Fast Grow Grass Seed. Thanks to the annual ryegrass included in this mixture, which is the fastest germinating grass seed variety, you can expect this seed to germinate in 7 days. It is designed to fill in troubled areas in lawns or grow an entire new lawn quickly.

Does planting depth affect grass seed growth?

Yes. Grass seed needs to be planted only ¼ inch deep and pressed into the loosened soil. If it is planted much deeper or covered with an inch or two of fresh soil, it will not germinate.

Does weather have an impact on grass seed growth?

Grass seed will germinate when soil temperatures reach a consistent 55° F and air temperatures reach a minimum of 60° F. If the temperatures are outside of this range, the seed will take longer to germinate or may not germinate at all.

How important is water in grass seed growth?

If there is too little moisture in your soil, the seeds will dry out.  Too much water will also hinder germination and prevent sprouts from getting the oxygen they need to survive.  Excessive spring rains can delay germination and, while watering newly planted grass seed is good for growth, overwatering will not make it grow any faster.

A newly seeded lawn should be watered at least every other day. Water deeply, at least 30 minutes in each area, to supply at least a half inch of water one inch down into the soil. This encourages the development of deep roots that help the new grass to become more drought tolerant.

Growing grass for your lawn involves more than just watering and waiting. Visit Jonathan Green online to learn more about how long it takes to grow grass seed and get answers to your other questions.
