Zigzag Goldenrod prefers consistently moist soil but can tolerate occasional dryness once established. Water deeply when the top 2-3 cm of soil feels dry, especially during hot, dry periods.

Avoid waterlogged conditions, which can lead to root rot. Reduce watering in winter when the plant is dormant.

Deadhead spent flower stalks in late fall or early winter to prevent self-seeding if desired, although it's generally not aggressive.

Cut back the foliage to the ground in late fall or early spring before new growth emerges. This tidies the appearance and encourages vigorous new shoots.

Zigzag Goldenrod can be propagated by division of established clumps in early spring or fall. Sow seeds outdoors in the fall or stratify them indoors for spring planting.

Stem cuttings can also be taken in early summer and rooted in moist soil or water.

Repotting is typically only necessary for container-grown plants or when dividing established clumps. If grown in a pot, repot every 2-3 years into a slightly larger container with fresh potting mix in early spring.

Ensure good drainage in the new pot.
