If you have a pine tree, you’ll inevitably have to deal with pine needles all over the place. I rake pine needles every Sunday, and there’s still nowhere near enough time to ensure the grass is spotless. It got me wondering if these small pine needles might have a big impact on the growth of the grass, weeds, and flowers in the yard.

Pine needles can kill grass because they deprive the soil and roots of oxygen, water, sunlight, nutrients, and airflow. You should remove the pine needles with a rake to stop them from damaging the grass roots. Letting pine needles pile up will put pressure on the grass, causing the blades to bend.

In this article, we’re going to talk about why pine needles are bad for your lawn, how you can stop them from killing the grass, and what you can do with leftover pine needles. We’ll also show you what pine needles can do to weeds and whether or not you can grow a healthy lawn under a pine tree.

Quick Suggestion: The SnapFresh Leaf Blower lets you blow away pine needles without sending them into the street. This battery-operated leaf blower has two settings. Using the lower setting lets you pile the pine needles, then rake them and throw them in a compost bin or yard waste bin.

What Do Pine Needles Do to Grass?

Pine needles can be good or bad for grass. If too many of them pile up without being raked or blown, the grass can become damaged or turn brown. You should take action as soon as possible with a regular routine to maintain the pile needles and protect your lawn.

Here’s what pine needles to do grass:

  • Pine needles can restore nutrients to the soil. According to Plant Care Today, pine needles decompose into nitrogen, calcium, and phosphorus. These three components promote healthy grass growth from seedlings and existing roots, but too many can be a problem.
  • Too many pine needles can deprive the soil of oxygen, sunlight, and water. These are the foundational properties of what most plants need to survive. Without them, the pine needles could be ruining your lawn in front of your eyes! Sunlight and oxygen typically only hit the top layer, which is why the grass can be damaged.
  • Excess pile needles will eventually kill your grass. As the grass blades bend under the pressure of the pine needles and their roots can get the nutrition they need to survive, your lawn will quickly turn to dirt and dead grass. Here’s what you can do to rake brown grass and thatch. However, the goal is to prevent this from happening.

If you’re tired of dealing with a patchy lawn caused by countless pine needles that never seem to go away, you’re not alone. My neighborhood is loaded with pine trees, all of which shed needles throughout the year. From the pine cones to the needles and sap, they can be a bit of a nuisance. In the next section, we’ll break down the steps you can take to keep your grass green while enjoy the beauty of your pine trees.

How Do I Stop Pine Needles from Killing My Grass?

To stop pine needles from killing your grass, rake them once or twice per week, use a leaf blower to remove excess pine needles, and toss them in a compost bin or waste can. You shouldn’t let pine needles build up because they can cause the previously mentioned issues to your grass. The good news is there’s a lot you can do!

Follow this process to stop pine needles from killing your grass:

  1. Use a leaf blower to blow all of the pine needles into a pile. This isn’t very necessary if there are only a few needles here and there, but if you have a big pine tree, a leaf blower will save hours of your time. Blow them into a pile on a low setting. Pine needles are very lightweight, so a high setting will send them flying into the neighbor’s yard.
  2. Pepper’s Home and Garden recommends raking pine needles as soon as possible because they’re slightly acidic. Their reduced pH can kill grass roots, alter the soil’s alkalinity, and cause many other harmful issues for your lawn. Rake them up and toss them into a garbage or compost bin of your choice.
  3. Set a schedule to do this once or twice per week. I tackle the chore every Sunday, but some weeks require an extra raking session. A good rule of thumb is to get out there and rake the pine needles if you can’t see the green of the grass. You should always see more green than brown or there’s an issue with the lawn!

These straightforward suggestions will make your grass live longer and stay greener, even if you have a pine tree. Many people dread pine trees and stay away from getting a house with one in the yard. However, these timeless trees are quite stunning and offer a home to many birds and other animals.

Will Grass Grow Under a Pine Tree?

Grass will grow under a pine tree if you remove the pine needles quickly enough. You can’t let them build up, even if it means raking them or using a leaf blower two to three times per week. Pine trees often drop lots of needles, cones, sap, and many other types of debris that can kill growing grass. However, that doesn’t mean you can grow it under a pine tree.

It’s also important to remove pine tree sprouts as soon as you see them. They’ll spread their roots, absorbing nutrients intended for the grass and other plants. Small pine trees growing from seeds will also shade the grass, limiting sunlight, oxygen, and water from hitting the roots and blades.

Will Pine Needles Kill Weeds?

Lowe’s claims pine needles will kill weeds. Some people collect pine needles and toss them all over a patch of weeds to limit the three aforementioned properties required for most plants (sunlight, water, and oxygen). The weeds won’t have anything they need to grow, so the pine needles will stop them in their tracks.

Unfortunately, the pine needles will also kill grass and other plants near the weeds. Anything under the pile of pine needles will experience growth problems. You can rake them into a small area to take care of weeds and other plants you want to get rid of, but make sure the pine needles don’t blow throughout the yard.

Another solution to get rid of weeds is to mow them. However, don’t let them get to the point of shedding seeds or it’s already too late. You’ll have to remove them by hand, which takes a lot longer than mowing or covering the weeds with pine needles.

What Do You Do with Fallen Pine Needles?

With fallen or dead pine needles, you can compost, make gifts, or toss them in the yard waste container. There are all sorts of items you can make with pine needles if you’re crafty enough. For example, you can make baskets, brooms, and more.

Here’s a quick and fun video tutorial of how you can make a DIY basket with pine needles from the yard:

Final Thoughts

Pines are some of the world’s most beautiful trees, but their needles can cause long-term damage to your grass. If you have a pine tree over your lawn, it’s important to rake the pine needles as often as possible to prevent them from piling up.

If you have plenty of dead pine needles around the yard, you can use them in a compost bin. Some people use pine needles to build brooms, hats, baskets, and more!
