When To Cut New Grass? We Have Answers!

You have just moved into a new house with a beautiful front lawn and gorgeous backyard teeming with lush, green grass.

That said, it is necessary to tend to your grass first, before working your way up to plants, flowers, herbs, and crops in your garden. Perhaps your lawn and backyard grass are just as brand-new as the house itself, so it has not been trimmed yet, let alone necessary so to do.

However, you are aware that you will eventually need to cut it after some time, but you are unsure as to when you would need to do so.

Hence, the big question is this: when should I cut new grass? You might be really uncertain, but there is no need to fret; we are here to help!

Learn more in this article on when to cut it, as we answer your frequently-asked questions. Soon enough, you will know exactly when to cut it and keep it in good condition.

Without further ado, let’s get started!​


When To Cut New Grass?


Depending on whether you have just seeded your grass or it has already been growing for quite some while now, a rule of thumb is to wait until it is about three to four inches in height before you can start mowing it down.

However, when it comes to mowing and otherwise cutting grass, it is advisable not to cut it too short. For the most part, you only need to cut it about one-third of an inch down.

At the same time, though, it will also depend on how quickly the grass grows back, so if it tends to grow back fast, then you either need to mow it a bit more than one-third of an inch or mow frequently.

Would It Pose Some Problems If I Do Not Cut The Grass?


Aside from looking extremely unattractive, overgrown grass can cause problems when it comes to its overall health.

In other words, it becomes weakened, thereby making it more susceptible to diseases and weeds, which in the long run can make it an unpleasant living condition.

Not only that, but also choosing not to cut your grass can lead to excessive grass clippings when you do end up trying to mow your lawn.

Normally, when the grass is only slightly overgrown, trimming it and receiving grass clippings can readily drop to the earth where they are absorbed into and provide nutrients to the soil.

For long clippings, though, they do not reach the ground, which can effectively block sunlight from entering and thereby causing malnutrition in the grass itself. Consider it, then, as a form of self-suffocation.​

To put it more simply, choosing to hold off on cutting grass can make it all the more difficult to cut it once you decide to do so, thereby jamming up the brush cutter or pruning shears for an unpleasant, sticky situation.​

What Are Some Ways To Keep The Grass Growing And Healthy?

Besides the obvious of trimming it regularly, it helps to do this list of activities in order to ensure that the grass remains green and in excellent condition:

1. Water Regularly

A no-brainer, it is essential that your grass remains well-hydrated in order to receive the proper nutrients to keep it healthy and growing.

Especially when it is first starting out, you will need to water it about twice a day, until it has matured enough to let you water it a couple of times a week.

2. Feed It

No strong, healthy grass ever came about without some fertilizer; although it smells extremely bad, it is necessary to have fertilizer in order to nourish it and have it grow straight and tall.

Along with watering it, the grass should be well on its way to good health.

3. Remove Weeds

Even if you do your very best to keep your grass well-groomed, there is always bound to be weeds popping up in it.

The trick is to mow your lawn several times before treating the area with weed-killer solution, so as to slow down and otherwise kill off weeds harboring around.

4. Get Rid Of Bugs And Pests

Similar to weeds, bugs and other pests are baneful. Treat them with bug-control products that you can obtain from your local home and garden store. Soon enough, they should be gone!


Overall, knowing when to cut new grass is good when it comes to timing and keeping it healthy at the same. By taking such measures, you can guarantee that your lawn will be in mint condition.
