Growing Conditions

Soil Adaptability: Thrives in virtually any well-draining soil including poor, rocky, or alkaline conditions with pH levels between 6.0-8.0. However, rich, loamy soil with good drainage produces the most abundant flowering and avoid constantly wet soils which can cause root problems.

Watering: Water regularly during the first growing season to establish deep roots. Once established, requires minimal watering except during extended drought periods - typically thrives on natural rainfall alone.

Pruning: Cut back by one-third in late winter or early spring to maintain compact shape and encourage vigorous new growth. Deadhead spent flowers to promote continuous blooming throughout the season.

Fertilizing: Apply a balanced, slow-release fertilizer in early spring for optimal bloom production, though these adaptable shrubs perform well even in nutrient-poor soils.
