Watering a Penstemon 'Andenken an F. Hahn'

The Penstemon 'Andenken an F. Hahn' thrives with consistent moisture, particularly during its flowering period from June through September. It's essential to ensure the soil is well-drained to prevent waterlogging. When watering, aim for the base of the plant to avoid wetting the foliage, which can reduce the risk of any potential issues. During hot spells, increase the frequency of watering to maintain soil moisture, but always allow the top layer of soil to dry out slightly between watering sessions to encourage a healthy root system. In cooler weather or when rainfall is sufficient, reduce watering accordingly.

When applying fertilizer, distribute it evenly around the base of the plant, avoiding direct contact with the foliage and stems to prevent potential burn. Water thoroughly after fertilization to help dissolve the granules and facilitate nutrient absorption. By maintaining an appropriate feeding schedule, this species will reward you with robust growth and a profusion of its characteristic red and pink flowers.
