Water regularly once the soil begins to dry out. Ensure good drainage to prevent waterlogging, as Orlaya grandiflora dislikes consistently wet conditions.

Reduce watering slightly during winter months when the plant's growth slows down.

Deadheading spent flowers regularly will encourage more blooms throughout the flowering season. Remove any yellowing or diseased foliage promptly to maintain plant health and appearance.

No significant structural pruning is usually required.

Orlaya grandiflora is easily grown from seed, sown directly outdoors in early spring or autumn. Seeds can also be started indoors a few weeks before the last frost date. Germination is usually straightforward.

This plant is typically grown as an annual or short-lived perennial and is not usually repotted. If grown in containers, they can be transplanted into the garden after the risk of frost has passed or replaced annually.
