Garden sorrel's geographical presence spans across multiple continents, being native to regions in Europe, Asia, and parts of Northern Africa. Garden sorrel also thrives in other domains, adapting to various climates and territories beyond its native range, including large areas of North and South America, Southeast Asia, and Oceania. In certain areas, garden sorrel is sometimes thought to be a robust presence, potentially exerting influence on native ecosystems, especially in locales such as Australia and New Zealand where its vigorous growth habit may have an impact on local flora.

Poisoning from garden sorrel occurs primarily through pollen or ingestion, causing tremors, salivation, diarrhea, and increased kidney stone risk. Its pollen can trigger hay fever. Toxic to cats and dogs, ingestion leads to vomiting, diarrhea, and more; immediate veterinary care is crucial. A higher risk for children and people with kidney conditions or arthritis.

Garden sorrel is native to Europe and southwestern Asia. It has spread to most agricultural areas except for equatorial South America and Africa. It is invasive throughout North America, Oceania, and Asia. In the United States, garden sorrel is banned or listed as invasive or noxious in several states and regions. It contains oxalic acid, which is considered mildly toxic to humans and animals. It spreads aggressively through rhizome roots and develops a large seed bank. These noxious qualities make it difficult to control or eradicate after it is established. Since garden sorrel prefers lower pH, soil can be amended with materials such as lime to raise the pH and discourage its growth. Crop rotation, mulching, and cover crops can be used to control established populations, but mowing and tilling are typically ineffective due to the rhizomes. Herbicides can also offer effective control.

The best time to remove garden sorrel is during the spring or early summer, before it has the opportunity to release its seeds. Now, let's talk about a few organic or creative methods to control its growth.
