White clover is native to Europe and central Asia, and south into parts of Africa and the Middle East. It grows in lawns and fields, prairies, and other places where there are few trees to block out light. In Japan, Australia, and the United States its spread is managed because this weedy plant is considered potentially invasive.

White clover poses a mild toxicity risk to cats and dogs. All parts of white clover are toxic if ingested in high amounts, causing symptoms like gastrointestinal upset and physical discomfort. Immediate veterinary treatment is crucial if poisoning is suspected to ensure the health of the affected pets.

White clover's native range includes Europe, western Central Asia, and parts of North Africa. Because it spreads efficiently by seed that can remain viable for years and survive both low temperatures and high heat, it was naturalized in North America, China, Australasia, southern Latin America, and parts of Africa. Although it is a desirable plant in many respects, from enriching the soil to being quality animal feed to providing food for pollinators, white clover is still considered a weed in some places, such as garden beds, lawns, and fields. Since it tends to grow in clumps, it is easy to remove manually, but it can keep coming back for years via seeds.

The best time to control white clover is during its active growing season, in late spring or early summer before it can spread its seeds. To keep this plant from turning into an unwanted weed or to cultivate it without letting it overtake the garden, follow these steps:
