Are Pine Needles a Good Choice for Mulching?

Many gardeners use pine needles as mulch.

Pine needles make a good choice for mulching for a variety of reasons. Pine trees naturally drop their long, narrow leaves, making pine needles an environmentally friendly choice. Gardeners can choose from 35 varieties of pine tree that grow across the U.S. for pine needle mulch.

Coverage

Lightweight pine needles cover a larger area than other mulches because of the long length of their leaves. Some species, such as the longleaf pine, possess needles as long as 14 inches. The lightweight quality of pine needles make them easy for gardeners to carry and distribute throughout a flowerbed. Because pine mulch is organic and will break down over time, it will need to be mulched over occasionally.

Erosion

While other mulch materials may erode after a heavy rainfall, pine needles stay put. This characteristic helps prevent soil erosion and discourage the growth of weeds. Pine needles also resist wind erosion.

Pests

Pine needle mulch does not attract termites, and protects plants from insects that approach stems from the ground. According to Texas A&M University, pine needle mulch also prevents soil-born diseases.
