Why are weeds bad in gardens?

Answer 1

Weeds suck-up a lot of water. So your plants won't get as much water as they need. In the end they'll die The main reasion is that weeds rob the other plants of nutrients that they need to thrive. i.e. (oxygen, phosphorus, potassium) and water. The root sytems of some weeds are very invasive and take over an area quickly. They can be difficult and expensive to get rid of them. Secondly, from an aesthetic viewpoint the weeds begin to crowd out the nice plants that cost you money to place in the garden and it looks unkempt. A good way to prevent weeds is to mulch the planting areas with a coverning of bark mulch (shredded redwood or cedar, small bark, or chips) about 2" thick. Replace as needed.

Answer 2

Weeds compete with garden plants for water and nutrients. So, if you have lots of weeds in the garden, your plants will be smaller and produce less. In some cases, the weeds grow so rapidly as to choke out the plants.

Answer 3

The weeds steal water and nutrients from the developing crops. Some weeds even give off natural herbicides, actually killing other plants in close proximity. Some also provide off-season habitat for damaging insect species.

Answer 4

Weeds choke out crops which increases competition for the crops to be able to grow. This in turn reduces yield which will bring the farmer less money at the "end of the day" so to speak.

Some weeds can also exude phytotoxic chemicals of their own, a natural herbicide that can kill any plants which try to encroach on the weed's territory.

Answer 5

Weeds are not neccessarily bad for your garden. A weed is simply a plant growing where it is not wanted. Some so called weeds can be extremely vigorous and can smother out choicer plants so therefore should be controlled.

Answer 6

Disease transmission, land invasions and resource monopolies are the effects of weeds on crops. Weeds can be hosts of such viruses as tobacco and tomato mosaic that endanger crop health and plummet crop yields downward. They have fibrous, near-surface roots that grab light, moisture and nutrients and multiple methods of reproduction, such as rooting of rhizomes, root and stem fragments and stolons and seeding, that invade land with no notion of space-sharing.

Answer 7

Weeds are simply plants where you don't want them. If it isn't bothering you leave it ,if it is howk it out.

Answer 8

They steal nutrients and compete with the other plants for water. They are good when dead because the decompose and add to the nutrients.
