watering
Water white evening primrose (Oenothera speciosa 'Rosea') deeply once per week, allowing the top 1β2 inches (2.5β5 cm) of soil to dry out before watering again. Do not water excessively as this will cause root rot. Water in the evening to reduce the risk of fungal diseases from water droplets lingering on the leaves.

pruning
Prune white evening primrose (Oenothera speciosa 'Rosea') early in spring before the new growth emerges. Prune the plant lightly, removing damaged or dead stems and branches, as well as any shoots that appear to be troubled. Additionally, the plant should be cut back close to the ground to encourage better blooming and bushier growth.
