How Long Should Your Grass Be? [Video]

The very first LawnStarter Mail Bag is here!

Every week, people write LawnStarter asking for advice on a variety of lawn care related topics. Some folks even send in some questions outside our area of expertise. We’re here to help, so those get answered as well…

Have you ever wondered how to ask for a raise?

Have you ever been curious about how to tie a tie?

Do you toss and turn at night fretting over how tall you should leave your grass?

If so, this video is for you.


Hi, I’m Aaron with LawnStarter, a lawn care company in Austin, TX. Every week, people write us requesting advice on how to better care for their lawn. So that’s what we’re going to do — give you advice to get a better looking lawn, today.

Let’s jump right in to our questions this week. We’ve got a few of them here and I’m really excited to get to answering some of these. Zack in Austin, TX, says, “Hey Aaron, how do I ask for a raise?” That is not at all a lawn care question. So, I guess if it’s by my experience, I’d say ask calmly, ask confidently, and just to be safe, make sure all of your personal belongings are already in your car. Don’t want to leave anything behind, in case it doesn’t go well.

Matt in Springfield, IL, asks, “Dear Aaron, how do I tie a tie?” I don’t know. This is a lawn care advice segment. Ask your brother or ask my brother, actually — he’s really good at it.

Lastly, Lindsay in Reston, VA, sks, “Dear Aaron, how tall should I leave my grass?” That’s a great question, Lindsay, and it’s one that we hear all the time. Now there’s no hard-and-fast answer because all grass is different. In fact, bent grass and zoysia can exist as low as half an inch to three-quarters of an inch perfectly fine. But most residential lawns, we recommend most of our crews cut at 3 inches. A good rule of thumb is never cut off more than one-third of the total length of a blade of grass, as that could stunt its growth and even compromise the integrity of the root system and, ultimately, your lawn and that would not be good.

Well, that’s all the time we have here. If you would like your question answered, please email or hit us up on Twitter at Thank you so much for watching. We’ll see you soon!
