A lush lawn is often the result of the right type of grass seeds, correct fertilizer and skillfully implemented aeration techniques. The important factors are the time of the year and the location as well as the climate which varies from state to state.

USA Climate Zones and Types of Grass Seeds

USA is divided into five basic climate zones and they are:

• Warm/humid
• Warm/arid
• Cool/humid
• Cold/arid
• Transitional zone (central and eastern part of USA)

Types of grasses recommended for each zone are as follow:

• Warm/humid – Bermuda grass or Zoysia grass
• Warm/arid – Buffalo grass or St. Augustine grass
• Cool/humid – Blue grass or Fescue grass
• Cool/arid – Blue grass or Rye grass
• Transitional – All types (may have to be combined with each other)

When to Plant Grass Seeds

There are no set rules for planting the grass seeds. The results greatly depend on additional factors such as type of soil, irrigation and amount of sun or shade. However, there are few general guidelines to follow.

• Cool weather grass seeds should be planted from late summer to early fall. The seeds will not be exposed to the heat of the summer, and the established grass will begin to hibernate allowing the young seedlings to assimilate most of the nutrients from the soil.

• Warm weather grass seeds should be planted from early spring to early summer. The temperature of 65 degrees during the day is the most favorable as the seeds will benefit from the warmer temperatures and have time to become established before the cooler days of the autumn.

• Follow the recommendations of the local landscapers and pay attention to the climate zones. Follow the instructions of the manufacturers of the seeds you purchase.

• Monitor the local weather and ensure that you do not sow the seeds before sudden frost, a heat wave or coming up storm. Any abnormal temperatures will hinder the germination of the seeds. If you have an opportunity, plan on sowing the day before light rain is expected. It will naturally and evenly water the ground without washing the seeds away.

What to Expect

The most important element of grass seeds sowing is the irrigation. Under the right conditions and with proper care, most seeds will sprout within two weeks. If you do not see any new growth, the reason is typically under or over watering. It is important to keep the soil moist to ensure quick germination. If you do not notice any results, the seeds may have to be replanted.

The grass seeds grow best in non-compacted dirt, so it is important to keep it loose and well ventilated. You may want to consider not walking over freshly sown areas of your yard. In addition, simple soil testing can be done to verify that your soil is not too acidic or too alkaline. The dirt should be properly balanced for each specific type of grass.

The best results are typically achieved when a top layer of fresh new soil is spread before planting new grass seeds. As an additional option, an organic fertilizer or compost may be mixed with the top layer as it will add extra nutrients and ensure accelerated germination. Most importantly, enjoy the experience and the fruits of your labor.
