Home and garden owners know that a good back yard or lawn needs to be free from weeds or killer plants that even if look good and can be used in the kitchen, also have the ability to smother and deter other garden plants. Affordable pest control and weed treatment and extermination plans are easy to find and implement, provided people make the difference between good plants and bad ones or ones with a higher risk of becoming impossible to manage. Five such plants represent a threat to the garden, in spite their good looks, medicinal or cooking uses.
The white spotted leaves of this plant are very decorative in those garden corners where there’s no turf, grass or flowers, but goutweed grows relentlessly and it’s almost impossible to get rid of it. The full green leaved species is even more aggressive, as it tends to spread and suffocate other plants and flowers. Although it can be used in the kitchen for salads and dressings, goutweed is considered a killer plant for the surrounding crops.

This is a very beautiful decorative tree, usually planted in shadowy areas and originates in Great Britain.

4. Black swallow-wort
One of the most invasive killer plants that can damage your garden, the Black swallow-wort needs sustainment in order to grow and spread. If you let it develop near a tree, it will soon gain control over it and slowly kill it by suffocating it and consuming all its nutrients. It spreads through solid roots, so it is quite difficult to get rid of it.
