| There are many benefits of
using mulch, and there are also many options of materials to use as mulch.
These mulch materials break down into organic and inorganic. I am
going to launch some unique mulch materials and ideas on this page, and
will begin adding images as I get time.
Why
use Mulch?
Mulching conserves soil moisture, reduces fluctuation in soil
temperature, and reduces competition from turf grass and other plants.
It also limits soil compaction of the root zone and provides the needed
organic material and organisms to build soil structure
Mycorrhizae Fungi- Most landscape
trees evolved in the forest environment. In the forest, a layer of
decaying organic material covers the ground. Within the layer of soil
is an organism called mycorrhizae fungi that greatly enhances the
function of roots. Urban environments often lack sufficient organic
organisms and porosity to functional and productive.
Ideal Soil Structure is: 50% porosity; 45% mineral soil and 5%
organic matter. The porous spaces should contain an equal mixture of air
and water. Note: Over 90% of a tree’s roots occupy soil space
in the top 24 inches of soil. The finer feeder roots are near the
surface, which is why porous organic matter and drainage below the
ground is so important to the overall health of you tree.
Problematic Mulch Textures:
Fine Texture: sawdust, grass clippings leaves, and small rubber shavings can restrict air
movement in root zone by forming a dense mate. Organic Mulch: Living mulches are cover crop plants that are
planted around and between the primary plants in a garden to control
weeds, prevent erosion, facilitate water penetration and improve the
soil. Living mulches thus serve a role similar to that of more
conventional mulches. Living mulch plants are sometimes used in
companion planting. |
