weeds in your garden and how to get rid of them
Background
to garden weeds in your garden
Garden
weeds in your garden are simply plants which are
growing in the wrong place. They are usually the
native plants which are best adapted to the environment
where they grow; sometimes they have been introduced
in the past for culinary, medicinal or decorative
purposes.
As
the garden weeds in your garden compete with other
garden plants for space, water and light, we try
to eradicate them before they swamp the more delicate
specimens. Even in a "wild" garden the
native plants must be controlled to give the more
pleasing effect we seek. The seeds they produce
can lie dormant in the soil for many years, germinating
when the soil is cultivated.
Types
of garden weeds in your garden
Garden
weeds in your garden can be categorised as follows:
Annual
garden weeds in your garden - these germinate
and mature in one season and die away leaving
a supply of seed to germinate in the autumn or
the following season, eg Cleavers & Groundsel
Biennial garden weeds in your
garden - take two growing seasons to mature enough
to produce seed, then die away. In the first season
they germinate in early summer and most grow as
a rosette of leaves at soil level, developing
a long taproot. In the second season they produce
an upright stem which flowers and seeds.
These
garden weeds in your garden are more easily removed
in the first year by uprooting or treating with
a contact herbicide at the seedling stage, but
a systemic or translocated agent is more likely
to be successful. If the flowering stem is prevented
from growing the plant may become perennial, it
is the production of seed which causes it to die
naturally. This can be seen with Thistles and
Ragwort when they grow in mown grass; the growing
point of the basal rosette is below the sweep
of the mower blades.

Perennial garden weeds in your
garden - these garden weeds form a storage system
in their roots or stems and live for many seasons.
They are the most difficult to remove as they
have a number of methods to ensure their survival.
First
they can produce seed which, as for Annuals and
Biennials, are dispersed by various means to reach
new ground as well as the surrounding area. The
other big advantage these garden weeds in your
garden have is that they can regenerate if the
topgrowth is removed or when the herbaceous perennials
die away naturally to survive adverse conditions
such as winter frosts.
This
perenniating system takes a number of forms, usually
it is underground as fleshy roots, stems or leaves,
in the case of bulbs. So when eliminating these
garden weeds the underground parts usually have
to be removed or destroyed to prevent regrowth.
Some have roots or underground stems which creep
around , eg. Bindweed, Ground-elder. Other garden
weeds spread using rooting stems or runners, eg.
Creeping Buttercup.
Many garden weeds in your garden can mature in
a matter of weeks and produce seed, if the growing
conditions are favourable, allowing them to have
several generations in a season. These are known
as Ephemeral plants due to this
transient behaviour. Examples are Chickweed and
Hairy Bittercress, which are usually categorised
as Annuals, although the latter can be a Biennial
if it germinates in the autumn.
How
to get rid of garden weeds in your garden
When
removing garden weeds in your garden, it is important
in most cases to uproot all of it and not to "graze",
otherwise it will soon re-grow. Use a hand fork
or a hand grubber (looks like a claw with 3 or
4 talons) to loosen the roots of larger garden
weeds.
For perennial garden weeds in your garden with
deep or widespread roots, a systemic weedkiller
such as Glyphosate may be required, this will
be taken down into the roots and kills the weed
in about 7 to 10 days. If you are opposed to filling
the coffers of the multi-national chemical companies
and you have the time, then mowing or strimming
an area of Nettles or Ground-elder will eventually
eradicate theses garden weeds.
This
method is not always feasible, eg.in a border,
but continually removing as many roots as possible
will eventually pay off, as the energy stored
in any remaining roots will run out, so be persistent
and don't allow garden weeds to grow enough leaves
to make more.
Dandelion,
Daisy, Pearlwort, Plantain and Creeping Buttercup
survive mowing, as they form rosettes at ground
level. If you do have invasive garden weeds in
your border tackle it in the autumn or spring
lifting the affected plants and teasing the invader
from their roots.
Use a fork when digging as it will tease the roots
loose, a spade will chop them up, thus multiplying
the problem. Garden weeds invading from adjoining
ground can be deterred with a barrier of thick
plastic buried vertically to a depth of about
30 cm and protruding above soil level by at least
10 cm (disguise it with a row of stones or gravel-board).
This is best done at the outset when preparing
the plot, but can be done later as a remedial
treatment.
