How far does the creeping myrtle tree root grow?

Creeping myrtle, also known as periwinkle or Vinca, typically has a shallow root system that spreads laterally rather than deeply. Its roots generally extend about 12 to 24 inches from the main plant. However, the exact distance can vary based on soil conditions and moisture availability. This characteristic makes it effective for ground cover but can also lead to it becoming invasive in some areas.
