Perennial wall-rocket is native to Western Asia and Europe but has been introduced to South America, North America, and Australia. This weed often roots in old walls and waste areas in USDA zones 5 to 9. It is recorded as an invasive weed in Australia, Spain, Argentina, the United Kingdom, and the United States. In Australia, the presence of perennial wall-rocket has been linked to lower crop yields of cereal and hay, constituting a threat to local farmers. When necessary, perennial wall-rocket can be removed through the use of chemical herbicides or mechanical methods (such as pulling by hand).

How to Control It

The best time to remove perennial wall-rocket is during the late spring or early summer, before it has a chance to flower and produce seeds.

Hand pulling: This is a simple yet effective method. Ensure to pull the plant from the base to remove all roots, otherwise, perennial wall-rocket might grow back.
Hoeing: This requires a gardening hoe. Use the hoe to sever the plant from its roots. Do this on a dry day to ensure the plants dehydrate and die off.
Smothering: This process involves covering the area where perennial wall-rocket is growing with a thick layer of organic matter like straw, old newspapers or cardboard. This blocks sunlight and prevents its growth.
Vinegar spray: Fill a handheld spray bottle with white distilled vinegar and spray it directly onto the perennial wall-rocket. The acid in the vinegar will kill the plant.
Introducing plant competition: Planting aggressive, easy-care plant species that can out-compete perennial wall-rocket for resources, ensuring its growth is restricted.
