There are many elements in consideration when you are finding the right mulch for your garden landscape. The argument can be understood by showing to you the standards of the different garden mulches.

Before we delve deeper, let’s try to answer a basic question a landscaping beginner would raise: Does mulch covering affect soil pH at all? More particularly, would the soil pH of your garden be diminished to some extent when you apply mulch?

The composition of your soil pH has a hefty impact on plant health. It’s logical that many people, including myself, have expressed unease on how garden mulch selection affects the soil pH, since it does influences the ground as it decomposes. Does using pine needles in your landscape mulch lead to your garden soil withering away? What about having oak leaves as mulch in your garden?

A popular belief of landscape professionals is that garden mulch has insignificant changes in the pH composition of your loam. For instance, while oak-leaf garden mulch may be acidic when fresh, most experts now say that it becomes more and more alkaline as it decomposes. In addition, based on latest gardening journals, garden mulch comprised with pine needles softens the soil pH to imperceptible degree, at any rate.

With the question of the potential impact of garden mulch on soil pH out of the way, let’s reflect on some other issues surrounding garden mulch selection — some of which are quantifiable, others of which boil down to personal landscaping preferences. Since a garden mulch can rate higher in one class only to perform poorly in another, we would then have to make a decision. Two obvious uses of garden mulch to which the reader will find little or no reference in this article are weed suppression and erosion control. They have not been included for a simple fact: a garden mulch done perfectly will eliminate weeds and erosion altogether.

Here are the three main frameworks of our discussions.

* “Insulation value in summer” is judged by the degree to which the garden mulch can keep the soil beneath cool and moist. A notable summer insulator will both lessen your need for watering and it guards the roots against severe heat.

* The problem of whether or not clearing away the garden mulch  in spring depends on the fact that abundant garden mulches can suffocate developing spring buds. This is clearly a non-factor for plants that is growing above ground. But even the latter can profit from having the soil around their roots warmed by the spring sun, a process facilitated by the temporary removal of the garden mulch. With regards to plastic sheet mulch, this factor is non-relevant since the material have holes that gives access to the plants.

* “Nourishment and aeration afforded to underlying soil by decomposition” is a standard used to distinguish the different landscape mulches. Though don’t be mistake the term “nourishment” into thinking that garden mulch and compost are the same.
