Native to a broad swath of Europe and Western Asia, small geranium is found in expansive, interconnected locations ranging from temperate to subtropical areas across these continents. Its reach extends from the Mediterranean basin to the highlands of Central Asia. Additionally, small geranium has been introduced to both the Americas and parts of Australasia, establishing itself in regions with compatible climates, illustrating its adaptability beyond its original habitat.

Small geranium is a weed plant that originated from Europe and Asia. The plant's weedy status is credited to its strong ability to regenerate and cover ground extensively. Its weed status is largely attributed to its dynamic reproductive system, which includes both sexual and asexual mechanisms. One of the most devastating features of small geranium is its capacity to produce prolific amounts of seeds. Each plant can potentially produce thousands of seeds, which are easily disseminated either by wind or water, or inadvertently by animals or humans. This ensures a rapid and extensive infestation of the weed, making it highly destructive to gardens. The weed's hardy nature allows it to flourish in diverse conditions, often outcompeting native plants for nutrients, light, and space, which eventually leads to a decrease in biodiversity.

The best season to remove small geranium is during the late spring or early summer, when the plant has not yet reached its flowering state. This prevents reseeding and spreading. Here are a few methods to control this weed:
