Weeds compete with cultivated plants for
moisture, food and light. Unfortunately, with few exceptions the
weeds always win the competition. That's why weeds need to be kept
under control. First lets deal with chemical weed killers. We don't
recommend them because they pollute the soil and plants which grow on
them. Sometimes however the weed problem is so wide that chemicals are
the only solution. We deal with chemicals in the weed identification
section of this article (see to left weed menu). There are two basic principles involved in controlling
weeds organically and they are: EXCLUDE LIGHT This is why a mulch can be used with great effect. A
mulch is a layer of material that is placed on top of the soil. It is
either strong enough to prevent weeds passing through it (e.g. black
plastic) or provides a barrier that is thick enough to make it very
difficult for weeds to grow through it (e.g. chipped bark).

then two methods of weeding should be used. Your first method is to
use a hoe to control the majority of weeds. Investing in a hoe, which
may well last a lifetime, will let you clear weeds much quicker and
more effectively compared to hand weeding. Click here for more details on hoes and how to
use them. Hand weeding is the only method that can be used where
the weeds are near the plant and using a hoe could damage the plants
or their roots. The aim of hand weeding is to pull up the the entire
weed, including the roots. It's best done when the soil is moist
because this will make removing the roots much easier. The basic idea
is to gently hold the visible part of the weed as near to ground level
as possible and tease the roots out of the ground. Some weeds, such as dandelions have very long tap
roots and it is often impossible to pull up the entire root. But try
and get as much as possible and you will have seriously weakened the
weed. Repetition of this as the weed reappears will eventually kill
it. Click here if

them.
Weeds get energy in the same manner as cultivated plants. They absorb
the energy of the sun and use it to grow. This process is known as
photosynthesis. Without sunlight weeds die. Some die quicker than
others but they all die eventually without sunlight.
There are many areas in a garden or allotment where mulch
it is not an acceptable solution. In these areas weeding is the only
solution. The first common situation is where an entire garden or
allotment needs to be cleared prior to planting. The second situation
is where a garden or allotment is planted and mulching between plants
is not convenient.
