Water regularly during the growing season, keeping the soil consistently moist but not waterlogged. Reduce watering in autumn as the plant begins to slow its growth.

Ensure good drainage to prevent root rot, especially in containers. Allow the top inch of soil to dry slightly between waterings.

Deadheading spent flowers encourages further blooming and prevents self-seeding if unwanted.

Lightly trim back any straggly or overgrown stems after flowering to maintain a tidy appearance and promote bushier growth in the following season. Remove any yellowing or diseased foliage promptly.

Easily grown from seed sown directly outdoors in autumn or early spring. Seeds require a period of cold stratification. Alternatively, sow indoors in early spring, about 6-8 weeks before the last frost.

Young plants can be divided carefully in spring if clumps become too large.

Generally, Adonis annua is not a plant that requires frequent repotting, especially when grown in the ground. If grown in containers, repot every 2-3 years in spring before new growth appears.

Use a well-draining potting mix and choose a pot only slightly larger than the current one.
