When to plant grass seed based on the season.

OK, then, let’s dive into the section of the article that matters the most. In order for you to understand, we are considering each season and how you should plant grass seed accordingly.

Fall Season

When to plant cool-season grass seeds in fall?

Talking about the cool-season grass seed, fall is the best time you can think of to plant. It really doesn’t matter the part you live in the country if you plant grass seed in fall. However, given you are living above the transition zone, our recommendation would be to plant cool-season grass seed from the latter part of the month of August to the start of October. For those who live south side, the time gets a wee bit extended as you have the luxury of planting seeds until the end of October.

When to plant warm-season grass seeds in fall?

It is completely the opposite for warm-season grass seed as fall doesn’t provide the ideal conditions for this variant. We say this because warm-season grass seed doesn’t get the needed time to germinate in the fall before the unforgiving winter weather conditions arrive. Yes, some grass types may get the time to germinate during fall, but they will find it difficult to survive in winter.

Winter Season

Irrespective of the type, you should never try to plant grass seed during the winter season. You just can’t expect grass to grow in winter as the weather conditions don’t permit the required background for the plants.

Spring Season

When to plant cool-season grass seeds in spring?

Although spring is not the best time to plant cool grass seeds compared to fall, most grass sorts have the tendency to grow without much of a problem in spring. Most people prefer from the start of April to mid-May for cool-season grass seed.

When to plant warm-season grass seeds in spring?

If you are planning to plant warm grass seed in spring, your grass will love your decision. Spring is the best time for warm grass seed. Concerning the time, it would be best if you choose the month of May to plant the seed. However, it’s your duty to provide sufficient water for grass to germinate before the scorching sun of summer.

Summer Season

When to plant cool-season grass seeds in summer?

Summer is not the best time for cool-season grass seed. Simply because the grass will be dormant during this time of the year; however, there is a slim window available for those who live far up North.

When to plant warm-season grass seeds in summer?
