Mulching is
one of the best things you can do in the garden. Mulch is simply a protective
layer of a material that is spread on top of the soil. Mulches should be
organic. Grass clippings, leaves, and other similar materials that you probably
have an abundance of around your property will make an excellent
mulch.
Mulching protects the soil from erosion, and reduces compaction
of soil from heavy rains. It conserves moisture, and helps to maintain a more
even soil temperature.
Organic mulches are best because they will also
improve the condition of your soil over time. Organic matter is a source of
plant nutrients and provides an ideal environment for worms and other
beneficial organisms that we all want to attract to our gardens.
Remember, the
healthier your gardens ecosystem is, the better chance you have for healthy
plants, and fewer pests and diseases.
One warning: If you use hay or
straw in the vegetable garden, you might end up with quite a few weeds since
hay and straw can harbor many kinds of weed seeds.
Mulch is
any type of material placed over the top of the soil to improve the soil. Mulch
helps the soil retain moisture and can improve soil conditions. Additionally,
mulch reduces weed competition by restricting the number of weeds that grow
around your landscape plants. You can improve the health of your plants by
using mulch around them to minimize damage by lawn mower blight and weed
whacking. When one practices proper mulching, it can actually help the
landscape maintain a healthy appearance. It can even contribute to the look of
a well-groomed landscape.
It is important, however, to properly apply
your mulch. If it is not applied properly, you might find that rather than
helping, you can cause harm to your plants and trees. There are many different
types of mulch. Just as there are different fertilizers, mulches come made from
different materials. They can be bought commercially, or you can create your
own mulch and save money.
The two main classifications of mulch are
inorganic and organic. Many people believe that all mulch is organic, but it is
not. Inorganic mulches, while more effective at keeping out weeds, will not add
to the composition of the soil, as it contains no nutrients to put into the
soil.
Inorganic mulches include various types of pulverized rubber,
some geotextile fabrics, and even stones and lava rock.
Organic mulches
are comprised of things like woods chips, bark, leaves, pine needles, compost
mixtures, cocoa hulls, and other mulches derived from plants. Even shredded
paper, used in small amounts, can contribute to organic mulch.
The
first thing to realize when properly applying mulch is that there is such a
thing as too much. Too much mulch can result in a variety of problems. Because
mulch does help retain moisture, too much mulch can lead to excess moisture.
Especially in trees, this can lead to root rot.
Do not pile mulch
against the stems of plants or the trunks of trees, as this can cause stress on
the plant tissues and lead to pest problems. Too much mulch can also alter the
pH of the soil, causing toxicities or deficiencies. Piled mulch provides nice
homes for rodents, which in turn may chew the plant roots and cause tree
girdling.
Fine mulch can become matted if too thick and then prevent
air and moisture penetration. Be aware of the type of mulch you are using.
Replace inorganic mulch each year, and if you have mulch that breaks down
slowly (like mulch containing cypress bark), do not add more mulch each year.
Wait until the mulch is mostly broken down before adding a new layer.
Proper mulch depth is about two to four inches deep, and not directly up
against trunks or plant stems. For trees, mulch should be applied at least out
to the drip line, with a space between the mulch and the tree. The drip line is
the border of the canopy of the tree. Root systems extend beyond the drip line,
so it is okay to spread a thin layer of mulch beyond the drip line.
In
order to properly apply mulch, it is important to take into account several
factors. You should first inspect the area. Find out if there is enough
drainage, you should also determine whether the type of mulch you will use is
compatible with the plants you have. Check the depth of already placed mulch
and do not add more if the depth is sufficient. Rake the mulch to prevent
matting.
There are vegetable-based dyes that can improve the appearance
of mulch that may be fading, but that does not need to be replaced. If there is
poor drainage, 2 inches may be too much. Apply a thinner layer of mulch in
these areas to prevent too much moisture retention.
The benefits of
proper mulching are many. When properly applying mulch, you are contributing to
the health of your landscape, making it more resistant to disease, insects, and
drought. Organic mulches also contribute to the make up of the soil, adding
nutrients and making the soil richer and better for the plants.
By
making good use of mulch, and avoiding excesses, it is possible for you to
increase the health of your landscape and decrease the costs associated with
maintenance and treatment. |
