Grass clippings make excellent mulch. They are easy to spread between small vegetable plants and if you have a lawn, you will have a steady supply to layer on throughout the summer.
Old newspaper also works quite well, especially against weeds.
Leaves are another material to use as mulch. Remember that forest floor? Leaf mold from the decomposed remains of leaves gives the forest floor that spongy structure and holds a heck of a lot of water.
You can also use old cotton or wool clothing cut into strips. You can even use old carpet like this, too.
Bark chips can be purchased through Organic Solutions, Inc. Our 6 different types of mulch are of the utmost quality and they will preserve soil moisture and eventually help your soil – and they look awfully nice in the garden.
Hay or straw can also be purchased as can seaweed mulches.
Another type of mulch is so-called ‘living mulch’. Organic Solutions, Inc. offers living mulch as well. I highly recommend using living mulch for you landscaping and garden. These are plants that grow very close to the ground under the main crop. They can grow very fast and have all the benefits of other types of mulch.
Some recommend plastic mulches but I strongly urge you to avoid this ‘plasticulture’. For one, you are adding nothing to your soil except, possibly, leached chemicals. Worse, covering your soil with plastic can kill the microbes and other life that will make your garden vibrant. Under plastic the soil can’t get the water, air and nutrients it needs to thrive. Plants grown with plastic mulches can very weak root systems that leave the plant malnourished and subject to damage from winds. With all the mulching options, I would avoid this one at all costs.
