For example, when compared to a redwood bark mulch, pine needles:
- Offer a nice reddish-brown color (although less vivid than that of the redwood bark)
- Offer good insulation from summer's heat and winter's cold
- Provide fair nourishment and aeration, but are excellent at allowing water to penetrate into the soil
- Are easy to apply (because they are so light-weight) and maintain
- Do not break down too quickly, thereby providing you with a long-lasting mulch

Why do pine trees need thin needles?
Pine needles are much more durable than normal leaves, which is why pine trees do not shed their needles each winter, but can instead keep them year after year. Pine needles are better at withstanding frost and will hold onto more water than standard leaves, making them ideal for cold environments.
Are pine needles really good or bad for composting?
The common misconception is that pine needles are actually bad for composting, but that is not true. One misconception about pine needles is that they cannot be composted. This is because pine needles have a high acidity level, with a pH between 3.2 and 3.8.

Why Does Acid Rain Not Acidify the Soil?
Southern Ontario can be considered to be a large limestone rock. Our soil has been created over millions of years from this limestone. Limestone is alkaline and so our soil is also alkaline. Mine has a pH of about 7.4.
How to make soil more alkaline?
Let’s say your soil is more alkaline than your plants want. The solution seems obvious – add something that is acidic. When you add acid to soil it should reduce the pH making it more acidic. Anyone who has taken basic chemistry in school has probably seen this take place in a test tube.

What are the benefits of pine needle mulch?
Pine needles provide all the advantages of any other mulching material, including conserving soil moisture, suppressing weeds, adding soil nutrients, moderating soil temperature and keeping plants and fruit clean during heavy rains. Additionally, pine needles have a tendency to stay loose and light, not forming an impenetrable crust like wood mulch. They are quite stable and do not tend to wash out of beds during heavy rains. In spots where it is difficult to keep mulch in place on a slope, pine needles may be the answer. Finally, pine needles are longer lasting than other types of organic mulch, and their fine texture is quite attractive against most permanent plantings.
Why do pine trees drop acid?
Eastern white pine ( Pinus strobus) is one of the dominant forest tree species in much of New Hampshire, and it grows best in places with acidic, well-drained soil. Pines grow where they do because the soil and climate are suitable, and they are not creating acid conditions themselves. When nothing grows beneath a white pine tree, it is probably because the tree has numerous shallow roots and is casting too much shade.
Can pine needles be used as mulch?
If you are unsure of the pH in your garden, you should have the soil tested. As pine needles break down and are incorporated into the soil, decomposing organisms gradually neutralize them. Thus, there is no harm in using pine needles to mulch shrub borders, flower beds and vegetable gardens . Even a 2 to 3 inch layer of pine mulch will not change the soil pH enough to measure.
What happens when pine needles fall to the ground?
When pine needles fall to the ground, they have left their life source (the tree) and begin to decompose. And that’s when the pH increases (acidity decreases) and they turn yellow and then brown.
What is the pH level of soil?
Most soils fall in the range of 5 to 7.5. A reading of 7.0 is neutral, below that is acidic, higher than that is alkaline.
Can pine needles cause acidity?
Plus, it may never happen if other neutralizers or alkaline substances like lime are present [1]. So no, pine needles acidity should not be a concern for gardeners. Blame the trees for being resource hogs, not the pine needles for any soil issues. And this brings us to another big misconception about soil pH.
Do pine needles affect soil pH?
Do pine needles alter the soil pH? When pine needles fall to the ground, they have left their life source (the tree) and begin to decompose. And that’s when the pH increases (acidity decreases) and they turn yellow and then brown. It’s the same for pine straw (pine needles) you can buy as mulch.

Between that and noticing that plants do not grow well under evergreens, or, more specifically, near conifers such as pine trees, it is assumed the dropped needles negatively affect the soil below.
Does pine straw mulch affect soil pH?
The presence of decomposing pine needles or pine straw mulch in a home garden is not going to change your soil pH, harm your plants, or boost the ‘acid-loving’ ones. Stick to the basics when growing plants: provide adequate sun, water, root space, nutrients, and air circulation.
Is pine needle acidic?
Pine Needles Are Acidic—But Only on the Tree. Pine needles are acidic (pH of 3.2 to 3.8, 7 is neutral) when they are living, green, and growing on the tree. This much is true. And that’s probably how the whole things started. Related: What is Soil pH and Why it Matters.
What is the pH of pine needles?
Pine tree needles are acidic when they fall, with a pH around 3.5. As they decompose, the pH of the needles raises to more neutral levels. Over many decades, the fallen pine needles may raise soil pH slightly if they are left on the ground. They will have some effect on pH if the fresh needles are dug into the soil.
How to neutralize pine needle acid?
Decomposition neutralizes pine needle acid naturally. Whether you rake the pine needles over bare soil as mulch or add them to a compost pile, the slow process of decomposition and bacteria in the soil will bring the pH level to a neutral level. When using pine needles as mulch, keep them at 3 to 4 inches deep and pull them at least 4 inches away from the stems or trunks of plants and trees. The loose mulch allows water to reach the soil while slowing evaporation.
What to plant under pine trees?
Successful plantings under pine trees incorporate shade- and acid-loving plant species suited for your hardiness zone. For a woodland-themed garden, add flowering shrubs like azaleas and rhododendrons (Rhododendron spp.), hardy in USDA zones 3 through 9, depending on the species and cultivar. The Old Farmer's Almanac recommends mulching rhododendrons with pine bark chips or pine needles to help keep the soil evenly moist.
What materials raise pH?
Purchase a pH-raising material. Sodium nitrate and calcium nitrate will have a rapid effect on soil pH, and add nitrogen to the soil. Hydrated lime will have a rapid effect on pH without the added nitrogen. Limestone, hardwood ash and steamed bone meal have a slower effect on pH levels.
