Michaelmas Daisies prefer consistently moist soil, especially during dry periods. Water deeply at the base of the plant, ensuring the soil is thoroughly saturated but not waterlogged.

Reduce watering frequency in cooler, wetter weather or during dormancy. Avoid overhead watering to minimize fungal issues.

Prune in late spring or early summer by pinching back stems to encourage bushier growth and more flowers. Deadhead spent blooms to prolong flowering and prevent self-seeding.

Cut back all stems to ground level after the first hard frost in late autumn or early winter to prepare for dormancy and prevent disease.

Easily propagated by division in early spring every 2-3 years to maintain vigor and control spread. Cuttings can be taken in late spring or early summer from non-flowering shoots.

Seeds can also be sown, though cultivars may not come true from seed. Division is the most common and effective method.

For container-grown plants, repot every 1-2 years in early spring into a slightly larger pot with fresh, well-draining potting mix. This refreshes the soil and provides more space for root growth.

When dividing, replant smaller sections into new pots or garden locations. Ensure good drainage in the new container.
