Can You Put Pine Straw Over Mulch? Mulch Ado About Nothing!

Can you put pine straw over mulch? Yes. Pine straw is in fact mulch, and mulch is a layer that you just keep feeding. I mulch my garden heavily and use an array of different organic materials. Read on to find out how pine mulch can improve your garden and reduce the amount of hassle you have with weeds.

Firstly, What Is Pine Straw?

Pine straw is quite simply the pine needles that fall below a pine tree. This forms a thick layer over time and can be harvested and sold. Commercial pine plantations can contain a very thick layer of this mulch and in certain places, this is harvested and sold. It can come in bags or even compressed bales. Or you can harvest it yourself.

What Is Mulch?

Mulch is a term we use to refer to a layer that we place over the soil. This is typically a layer of leaves, wood chips, manure, and other organic matter. It protects the soil from sunlight, helps to retain moisture, and feeds a community of microbes that include bacteria (fixing nitrogen), fungi (breaking down complex organic materials into humic substances), and larger creatures such as earthworms and woodlice that help to feed the soil and aerate it.

What Are The Benefits Of Mulch Layers?

A mulch layer mimics the layer that occurs in nature on a forest floor. Leaves and branches fall from large trees and cover the floor in a natural mulch. This mulch allows the growth of fungi and microbes that help to produce nutrients for plants. Fungi also connect the trees through a root network of mycorrhizae. These networks can be really huge!!

By having a layer of mulch in your garden, you mimic a healthy natural ecosystem, and this provides a number of benefits.

Mulch helps to preserve soil moisture – it reduces the impact of wind and sun on the soil in terms of stripping water away.

Mulch helps to keep the soil at an ideal temperature – it helps cool the soil by day, and keep it warm by night, providing roots with a more balanced temperature regime.

It provides nutrients through the natural breakdown of complex organic matter in the soil into nutrients and less complex substances.

It provides a home for beneficial soil organisms such as earthworms, and insects that eat pests.

Mulches feed mycorrhizae and help to keep your soil healthy and your plants connected.

In Conclusion – Can You Put Pine Straw Over Mulch?

Yes, pine straw is mulch. So you can use it in your mulch layer. I believe an entire garden should be mulched, to create a corridor of communication between all plants. I mulch my pathways, I mulch my garden beds, I mulch under my trees. This means that my garden is greener, healthier, and way more alive than any other garden in my town. Mulch is the most important part of a garden in my opinion as it keeps the soil alive – and without living soil, your garden becomes dead and dependent on fertilizer.

I offer local lawn and garden maintenance companies the opportunity to dump their bags of garden waste at my gate. This means they do not have to drive as far to dispose of this, and I, therefore, receive a huge variety of organic materials to mulch my garden. At times this layer can be up to two feet deep! The more I mulch, the more my soil thrives and the more my garden flourishes.
