Culture

Caring for Heuchera ‘Electric Lime’ involves understanding its specific cultural requirements to ensure optimal growth and performance. From watering needs to soil preferences, here is a comprehensive guide to cultivating this stunning plant.

Water

Heuchera ‘Electric Lime’ prefers moderately moist soil and is sensitive to both drought and waterlogged conditions. To provide the ideal moisture levels, it is essential to water the plant consistently, especially during dry periods. However, it is crucial to avoid overwatering, as excessive moisture can lead to root rot and other issues.

• Watering Tips:
