Pine Needle Mulch – The Ultimate Guide

Share on:

Pine needle mulch has many benefits, and it’s easy to make yourself. In this article you will learn everything you need to know about this type of mulch.

One of the best things about home gardening is experimenting with different ways to take care of your plants. If you’re looking for a natural way to mulch your garden, consider using pine needles.

What is pine needle mulch?

Pine needle mulch is a type of mulch made from pine needles. It is used in gardens and landscaping to help prevent weeds, conserve moisture, and protect plants, like most mulches are. Pine needle mulch can also be used as a soil amendment to improve drainage and aeration.

Made from pine needles that have been shredded or pulverized, pine needle mulch is usually reddish-brown and has a fibrous texture. It’s sourced from pine trees, typically Pinus sylvestris or Pinus ponderosa.

It’s a popular mulch among gardeners because it is lightweight, easy to spread, and does not compact like other types of mulch. It can also be used as a compost material. Pine needle mulch decomposes slowly, so it should be replaced every year or two.

Pine straw vs. pine needle mulch

What is the difference between pine straw and pine needle mulch? They are the same, but since we’re getting technical, let’s discuss the differences.

Pine needles are just the raw version of pine straw. Pine straw is the dried version of pine needles. When we refer to pine needle mulch, we’re generally talking about dried pine needles being used as mulch. So, pine straw mulch and pine needle mulch is pretty much the same thing.

Pine straw pieces might be shorter than non-dried pine needles. This is because once the pine needle has dried (into pine straw), it can break more easily. When you buy or make pine straw mulch, you will likely end up with a certain percentage of your mulch as shorter bits of dried pine needles rather than each needle measuring the same length.

What are the benefits of pine needle mulch?

Aside from the general benefits most mulches provide, this mulch is an excellent resource for any gardener looking to improve the quality of their soil. Here are some of the benefits of pine needle mulch.

  • Adds organic matter to the soil as it decomposes
  • Helps to regulate moisture levels
  • Keeps weeds at bay
  • Helps prevent soil erosion
  • Protects soil microbiome from harsh sunlight and high temperatures
  • Helps raise the soil temperature of your garden in the cold spring and autumn seasons
  • Discourages some plant diseases and certain pests from bothering your plants

Pine needle mulch is an affordable and environmentally-friendly way to improve the health of your garden.

Where to find pine needle mulch?

For gardeners looking for an effective and natural mulch option, this mulch is hard to beat. The only challenge is finding it since pine trees aren’t found everywhere in the world.

Many garden centers and nurseries sell pine needle mulch. Here are a few options to choose from if you are looking to buy pine needle mulch online:

USA Pinestraw (Bulk option)

This bulk box of pine straw mulch covers up to 300 square feet of space. Perfect for landscaping projects or extensive gardens in need of mulch. This pine straw mulch comes compacted in a box, so you’ll likely take several hours to spread it around your yard or garden, depending on how much ground you need to cover.

Because of the compaction, it will take a little longer than spreading wood mulch will. That said, this pine needle mulch stays in place efficiently after it’s been watered for the first time. And based on the reviews, it can last up to three years without needing additional applications.


USA Pinestraw (Singular bale)

This is a smaller amount of pine straw from the same American pine straw company, which is a great option if you’re working with a smaller area to mulch. 

Colored Pine Straw (Pine needle mulch rolls)

This company has an innovative take on pine needle mulch, offering a rolled-up bale of pine straw that you can simply roll out onto your lawn or garden. It’s made of the same stuff (100% natural, dried pine needles) and just as eco-friendly as buying a bale. You can trim it to size if needed. This product will take less time to apply than buying a bale or box of pine straw, but it is generally a bit more expensive. 

Making pine needle mulch at home

Pine needle mulch can also be made at home. Simply gather pine needles around your property (or ask a neighbor if you can collect theirs) and then spread them around your garden beds. Within a few weeks, you’ll have a healthy layer of pine needle mulch to help your plants thrive.

If pine needles are hard to come by in your local area, ordering online will be your best bet. Though, it may be worth exploring a mulch option you can buy locally if you’re concerned about sustainability.

What plants is pine needle mulch good for?

Pine needle mulch and pine straw mulch can be used on almost any kind of plant.

Pine needle mulch is acidic, making it rumored as unsuitable for use around alkaline-loving plants such as azaleas and rhododendrons. This is generally untrue, however. It’s been shown that pine needles don’t really affect soil pH.

Instead, pine needle mulch is best used in areas where you want to encourage the growth of mosses or other acid-loving plants. It can also be used to create an attractive groundcover around Acidic loving plants like camellias, gardenias, blueberries, and hollies.

If you are nervous about using pine needle mulch around alkaline-loving plants, apply it sparingly and avoid letting it come into contact with the leaves or stems of the plant. But ultimately, your plants will probably be fine after applying pine mulch or pine needle mulch.

One situation where you may not want to use pine needle mulch is if the area you live is overly wet. Pine straw mulch can lock in quite a lot of moisture, and if your garden beds or yard is getting rained on regularly, you may begin to experience issues with moisture-loving pests like slugs and snails. However, pine straw mulch will likely be a good fit for milder and drier areas.

How to apply pine straw mulch in your garden or yard

Applying pine needle mulch is a similar process to putting down any other kind of mulch. Here are the steps you’ll want to take when it’s time for your mulching project.

  • Measure the area of the space to determine how much mulch you’ll need to buy.
  • Multiply this number by 2 or 3 since adding 2-3 inches of pine straw mulch is generally recommended.
  • Purchase that amount of mulch, plus 10-20% extra to account for spillage or miscalculations. (You can add the extra to your compost pile if it’s not needed.)
  • Prepare the area to be mulched by pulling weeds, removing rocks and decor, adding any soil amendments, and watering the soil.
  • When your mulch arrives, plant any new landscaping or garden plants you’re adding to the area right before applying the mulch.
  • Finally, apply a 2-3 inch layer of your pine straw mulch and spread it out evenly. Avoid placing the mulch directly against the stems of plants or trunks of trees.

Six ways to use pine needles or pine straw in your garden

Pine needle mulch is an excellent way to improve the quality of your soil, but it can also be used in various ways. Here are six ways to use pine needles in your garden:

1.    Mulch

Pine needles make excellent mulch for your garden. Mulch helps to suppress weeds, retain moisture, and protect your plants from extreme temperatures. As an organic mulch, pine mulch or pine needle mulch will also add nutrients back into your soil after it breaks down.

2.    Compost

Pine needles can also be added to your compost pile. Compost is a great way to add nutrients and improve the structure of your soil. Pine needles will help to accelerate the composting process and add valuable nutrients to your soil.

3.    Soil amendment

Pine needles can also be used as a soil amendment. Spread a layer of pine needles over the surface of your garden bed and dig them into the top few inches of soil. This will help improve drainage and aeration while adding nutrients to the soil.

4.    Natural fertilizer

Pine needles can also be used as a natural fertilizer for your plants. The needles release nutrients slowly over time, making them an ideal fertilizer for both annuals and perennials. Simply scatter a handful of pine needles around each plant every few months and water them in well.

5.    Pest repellent

Pine needles can also be used as a pest repellent. The strong scent of pine is off-putting to many pests, including ants, beetles, and slugs. To use pine needles as a pest repellent, simply spread a layer around the perimeter of your garden or sprinkle them over problem areas.

6.    Weed killer

Pine needles can also be used as a natural weed killer. Pine needle tea’s acidic nature helps kill weeds quickly and effectively. To make pine needle tea, simply steep a handful of pine needles in boiling water for 10 minutes. Once the tea has cooled, you can then use it to spray problem areas in your garden.
