Description
Violets found in lawns often originate from neighboring flower beds or wild varieties. Highly competitive and aggressive, they adapt well to both sunny and shady areas. They are characterized by heart-shaped leaves and flowers that range in color from purple to blue.

- Season of appearance: Spring to autumn
Causes
They develop in sparse lawns, on clayey and acidic soils, and near flower beds containing cultivated violets.
Prevention
- Perform lawn topdressing followed by overseeding to thicken the grass.
- Correct soil acidity if necessary to limit their spread.
- Aerate the soil to improve growing conditions.
Control
- Violets are difficult to control with herbicides, making prevention essential.
