About Juncus diffusus
Juncus diffusus, commonly known as Diffuse Rush, is a perennial aquatic or semi-aquatic plant belonging to the Juncaceae family.

Care tips
This plant thrives in full sun to partial shade, requiring at least 4-6 hours of direct sunlight for optimal growth. It needs consistent and abundant watering, keeping the substrate always moist or even with its feet in water; it does not tolerate drought. It prefers clayey or loamy soils, rich in organic matter and well-drained, although it adapts to a wide range of wet substrates. A common mistake to avoid is letting the substrate dry out completely, which can lead to yellowing and drying of the stems.
