Beardtongue (Penstemon digitalis 'Blackbeard') should be watered thoroughly about once a week during the growing season (spring through early fall). Water deeply to keep the plant's root zone evenly moist. It is important to avoid over-watering, which can lead to root rot. During the hotter summer months, you may need to water it twice a week as the plant uses up more water with increased heat and sunlight. During the winter months, when the plant is dormant, it may not need to be watered more than once every 2 weeks. If you feel the soil is dry, give the plant a light drink to keep it from drying out.

Beardtongue (Penstemon digitalis 'Blackbeard') prefers direct sunlight for 3 to 4 hours per day and can tolerate partial shade if necessary. It prefers to be grown in an area that receives at least 6-8 hours of bright, direct sunlight each day for best flowering and growth. However, too much direct sunlight for extended periods each day can cause withering or burning of the leaves. If this occurs, simply move the plant to an area with more shade or less direct sunlight.

Beardtongue (Penstemon digitalis 'Blackbeard') should be lightly pruned in late winter or early spring, shortly before the new growth begins to form. Cut back the flowering stalks right to the basal foliage. Remove any dead or diseased foliage as soon as you spot it, and any stems that aren't blooming properly. Make sure you don't over-prune as this can disrupt the flowering cycle for the season. Pinching new growth back in late spring will help to promote more branching and additional blooms; however, do this sparingly.
