Soil
Soil Conditions: Well-draining, fertile soil is essential for the healthy growth of Clematis ‘Blue Angel’. It thrives in soil that retains moisture without becoming waterlogged and provides the necessary nutrients for robust development.
Soil Requirements:
– Texture: Loamy soil with a good balance of sand, silt, and organic matter is ideal for Clematis ‘Blue Angel’.
