Reduce watering in winter when the plant is dormant.
Deadhead spent flowers regularly to encourage continuous blooming and maintain a tidy appearance. Cut back the plant by about one-third in late autumn or early spring to promote vigorous new growth and prevent legginess.
Propagate Oenothera speciosa through division of established clumps in early spring or autumn. Seeds can also be sown in autumn or early spring, either directly outdoors or in a cold frame.
Root cuttings can also be taken in summer.
Repot Oenothera speciosa every 2-3 years, or when the plant becomes root-bound. Spring is the ideal time to repot, using a well-draining potting mix. Gently loosen any circling roots before replanting.
