why are dandelions weeds

Dandelions are considered weeds primarily because they spread aggressively, compete with other plants for resources, and are difficult to fully eradicate due to their deep taproots. Their seeds disperse widely by wind, allowing them to quickly invade lawns, gardens, and landscaped areas, often overtaking more desirable plants. Additionally, if dandelion roots aren't completely removed, they can regenerate, making control labor-intensive. Despite their appeal and usefulness (like being edible and medicinal), their invasive nature and ability to outcompete other plants classify them as weeds in gardening and lawn care contexts.
