Transplanting should be done in the fall when the soil is still warm for better establishment.
Watering Needs
Ensure the soil is kept moist but not waterlogged. During the growing season, water regularly to keep the soil evenly moist, especially in periods of dry weather. Watering should be reduced in the late summer, as the plant enters dormancy in the winter.
Avoid overhead watering as it can lead to disease and fungal infections on the foliage, especially during periods of humidity. Ensure to water at the base of the plant, avoiding any water reaching the leaves.
Fertilization
Penstemon eriantherus does not require heavy fertilization, especially if grown in soil rich in organic matter. However, you can add slow-release fertilizers with a balanced nutrient composition such as 10-10-10, in early spring to promote lush growth and bloom formation.
Ensure to follow manufacturer's instructions on the dosage and application methods to avoid excess buildup of nutrients in the soil.
Pruning
Deadheading of faded flowers and cutting back stem tips by one-third in late summer after bloom has reduced can encourage the plant to produce more flowers, and ease propagation by stem cuttings. If the plant becomes too straggly, annually pruning of the tops of the stems to about half of their height can help control the size, promote bushier growth and ensure a denser and healthier plant.
