Penstemon spectabilis prefers well-draining loamy soil. It can tolerate poor soil conditions but thrives best in soil that is not too rich in nutrients. Ensure the soil dries out almost completely between waterings to prevent root rot.Fertilizer
This plant does not require frequent fertilization. If needed, a balanced, slow-release fertilizer can be applied sparingly during the growing season.Repotting
Repotting is generally not necessary for Penstemon spectabilis unless it outgrows its current container. If repotting is needed, do so in the early spring before the growing season begins. Use a well-draining soil mix and a container with drainage holes.Propagation
