What Soil Mix Works Best for a Rugel's Nailwort?

Well-draining sandy soil mix with added organic matter. Good drainage is essential for Rugel's Nailwort to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Rugel's Nailwort?

Feed Rugel's Nailwort every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.
