dew flower

Dewflower (Penstemon cobaea) should be watered when the soil's surface feels dry. Be sure not to over-water the plant or it may develop root rot. Generally, water thoroughly once a week during the summer months, allowing the soil to dry out slightly in between waterings. However, water more frequently during times of extreme heat, or if the soil feels very dry. During the cooler months, water deep and less often, allowing the soil to dry out slightly between waterings. During dormancy, water very lightly, just enough to keep the soil barely damp.

Dew flower (Penstemon cobaea) prefers plenty of sunlight throughout the day in order to bloom and grow properly. This plant species thrives best in areas that receive around 5 to 8 hours of direct sunlight. During the warmer months when there is more intense sunlight, the flowers will need less than 5 hours of sun. But during the cooler months, the plants should receive at least 8 to 9 hours of direct sunlight to grow and thrive. Placing the plant in an area that receives more than 8 hours of direct sunlight is acceptable, but 1 should be careful not to place it in an area that is in direct sunlight all day as the direct rays of the sun can damage the flowers.

Dew flowers (Penstemon cobaea) should be pruned in late winter to early spring, when the plant has gone dormant. Pruning can be done by cutting out the actively growing shoots that have overgrown the desired shape of the plant. This will ensure that the resulting shape of the plant is neat and uniform. Make sure to prune as many of the older stems at the base as possible, as this allows new growth to shoot up from the base. Avoid pruning too much, as this can lead to leggy, weak-looking growth. Additionally, if the flowers have finished flowering, leaving the dead flower spikes on the plant can help foster new growth.
