Let’s answer our main question: When to mow new grass? Even if it will seem like a long period of time, you need to wait until your new grass blades are uniformly at least 3 and a 1/2-inches tall, then you mow them.

Bear in mind that long blades do not require much water, will discourage weed formation during the establishment phase, and as a result allow all of the grass’ energy to be focused on developing drought-resistant, deep, and strong roots. 

In the establishment phase, the root development is the largest determinant in the long-term health of the lawn.

In addition, it’s so important not to mow during this phase because it keeps your feet and mower off of the lawn, which is the weight of which can make micro-tears in the growing roots, delaying their establishment.

You have to wait at least 3 to 5 days before making a second mowing pass again, you should also make sure you remove no more than a third of the remaining length.

It’s particularly important than when to mow new grass or lawn, you always want to cut grass with clean, sharp mower blades. That is to say, new grass is more flexible, tender, and finer than more established grass. 

However, dull cutting blades cannot make a clean cut on new grass, and have a tendency to tear and bend, or even pull on the grass blades that can harm the roots and at the tear points invite disease into the blades. 

What’s also crucial is that blades have to be clean, because blades with buildup from previous use may harbor disease, or decaying material.

This can get introduced into the fresh cuts on the young lawn, and as a result, spread bacteria and fungus into the new grass. 

To wipe down the mower blades, you can use either household isopropyl alcohol, or a bleach solution made of one part bleach and ten parts water on a clean rag or cotton padding.

And to loosen any built up dried material or rust on the blades, you can use a scrub brush. 

Otherwise, you can make your mower taken care of by a professional who can both clean and sharpen the cutting blades before embarking on mowing your new grass.
