Leaf size: approximately 3 inches.

Lychnis arvensis requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Lychnis arvensis to prevent waterlogging, which leads to root rot and fungal issues.
