watering

Coastal wallflower will need to be consistently watered to keep the soil moist. During active growth, water deeply as needed, allowing the soil to dry slightly between waterings. During the summer, this plant may require more frequent watering, about every 5 to 10 days. In the winter, when the plant is dormant, they will need to be watered much less, about every 3 to 4 weeks.

sunlight

Coastal wallflower, or Erysimum capitatum, does best when it is exposed to full sun. This sun-loving species prefers a minimum of 6 hours of sun per day for optimal growth. During the peak of summer, it may even need 8 hours of sun to stay healthy and remain in full flower. Ideally, the coastal wallflower will receive its daily onset of sunlight in the early morning, around 8am, and no later than 4pm in the afternoon. However, during the cooler months, this plant species has shown some tolerance for exposure to lower and indirect sunlight.

pruning

Coastal wallflower can be pruned twice a year - once in spring and once in fall. Each time, cut back the plant by no more than 1/3 of its overall size. To ensure healthy growth, remove any dead or diseased stems. This should help promote the growth of flowering stems. For more severe pruning, you can wait until spring and cut back to 6 inches above the ground. If you are pruning for shape, it’s best to wait until the end of flowering and cut back the stems to shape. Pruning is typically done during the dormant period for the plant, which is late fall to early spring.
