How to Care for the Plant

Water
Jacob's ladder plants that receive regular watering will bloom longer and remain attractive into summer. Water regularly to maintain medium moisture levels, but avoid soggy conditions. During dry periods, you may need to water more frequently to keep the plants lush.
Pruning
In general, Jacob's ladder requires minimal maintenance. Once the flowers finish blooming, cut the flower stalks back to the plant's base to encourage repeat blooms. If the foliage starts to look tattered, it can also be cut back and cleaned up. New growth will replace the trimmed foliage.
Fertilizer
Polemonium caeruleum is a long-lived perennial in the right conditions and if it is fed properly. Give the plants a boost in early spring with a dose of balanced fertilizer as the new growth is emerging. Feed them again once the faded flowers have been cut back.
