The Overseeding and Mowing Process

When you set out to overseed your lawn, you will need to go through series of steps to enable the success of your effort. You will begin the efforts by mowing your lawn, and then you will perform the overseeding. You will need to water daily, in most cases, until your seeds germinate and have reached a certain height. A regular schedule of cutting can then begin. Let’s take a look at the process here:

1. Site Preparation

Before you begin to start overseeding your lawn, you will need to prepare your areas. Acquiring the proper type of seed in Lexington is important. For best results here in Lexington, a turf type fescue is recommended. Remember this, the best time of the year for overseeding is the Fall. Fescue lawns require 2 growing seasons for the root systems to be established enough to withstand the hot summer months. Overseeding in the fall allows the seeds to germinate and establish, followed by another growing season in the spring. At this point, your lawn will be established and better able to withstand the heat and drought common in Lexington.

  • Lawn mowing. An initial mowing of the lawn should be done shorter than normal. This will allow the overseer to reach disturb the surface of the soil so the seeds can find purchase. Removing grass trimmings and raking the area to prepare the soil surface is also ideal and is advised. Removing rocks, stones, debris, or other obstructions and providing a clean surface to overseed is necessary.
  • Overseed the lawn area. Apply your seed as directed by the supplier on the labeling of the seed you acquire to perform the overseeding. Begin with a watering of the area immediately after the overseeding so the seed sticks to the ground and is not blown away and so that the process of germination sets in and begins.
  • Fertilizer. It is advised that you use a starter fertilizer at the same time that you overseed your lawn. It’s important to note that it is a starter fertilizer. If you are doing this as a home owner, look for a fertilizer with a composition of 10-18-10. If you have any questions, just give Hey Mow! a call. 
  • Watering. Water immediately after overseeding. It is very important to keep the soil moist until the grass is established and healthy.
  • Weed control. Avoid weed control in all circumstances, as it can damage the growing grass seed and hamper your efforts to achieve success in overseeding.

2. After Overseeding Mowing Practices

When to cut grass after overseeding? The typical timeframe you will want to pursue cutting your grass again after going through the overseeding process is within 3-4 weeks, when the grass seedlings are about 4 inches tall and can withstand an initial cutting. You will want to cut the new grass once per week after that along with the other grass on its own schedule. Sometimes it can take up to 4 weeks before the grass will grow to the height where it can be cut initially.

Different varieties and strains of grass seed will yield different results and require longer or shorter timeframes for germination, and therefore until they are first cut after overseeding. The general rule is that the new grass is 4 inches tall however, and at that point it should be cut on a regular schedule in time with the rest of your lawn.

3. How to Maintain Your New Lawn

You will need to maintain your lawn on a regular basis according to a schedule you design or have created for you by a professional lawn care company. You will need to water your lawn consistently to get the best results. Regular seasonal fertilization is recommended. Weed control is also a good idea, but with newly grown grass you should wait for the following spring before applying any weed control or preventers. Regular cutting should be performed, with the 1/3 rule being applied to all cutting (maximum 1/3 length of grass cut at any one time) for optimum grass health.
