Why are dandelions bigger at the edge of the field and not at the middle of the field?

Dandelions tend to be bigger at the edge of a field due to several factors, including increased sunlight, moisture, and nutrient availability, which are often more abundant in areas close to the surrounding environment. Additionally, edges typically experience less competition from other plants and are less disturbed by agricultural activities, allowing dandelions to thrive. In contrast, the middle of the field may have more competition, reduced light, and more intensive management practices that hinder their growth.
