White mustard naturally grows in the temperate climates of major regions including northern Africa, western and central Asia, and across Europe. This plant has been introduced to various other parts of the world such as parts of Central and South America, the Indian Subcontinent, Southeast Asia, and Oceania. It has established itself in these new environments, expanding its presence beyond its original habitat.

White mustard hails from the Mediterranean region. Being a weed, it has certain characteristics making it harmful, especially to gardens. White mustard grows rapidly, producing a high seed yield that can take over other plants for resources. It's particularly harmful because it hosts pests and diseases such as aphids, flea beetles, and fungus, posing threats to nearby plants. Spotting white mustard in your garden is relatively easy; look for bright yellow flowers, large lobed leaves, and round seeds in a long, slimmer pod. The plant thrives in various soil types and climates, making it a competitor to other plants for survival. Its primary mode of spreading is through its seeds, carried by the wind or wildlife, or unintentionally spread by human activities. Adequate control methods need to be implemented to prevent its excessive growth and to protect the other plants in the garden.

The control of white mustard is best tackled in the early stages of growth, particularly before it sets seed. To limit the spread of white mustard, control measures should be implemented before the plants flower.
