Care guide for Giant Forget-Me-Not

Watering, pruning, propagation, and repotting details from plant data

Water

Keep the soil consistently moist but not waterlogged, especially during the growing season. Reduce watering in winter, allowing the top layer of soil to dry slightly between waterings.

Avoid overhead watering to prevent fungal diseases on the large leaves.

Pruning

Remove spent flower stalks promptly after blooming to encourage further flowering and prevent seed formation. Cut back any yellowing or damaged foliage to maintain plant health and appearance.

Prune in late winter or early spring before new growth begins.

Propagation

Propagate by division of established clumps in early spring. Carefully divide the root ball into sections, each with a few healthy shoots and roots. Replant the divisions immediately into well-draining soil.

Can also be grown from fresh seed sown in autumn.

Repotting

Repot young plants annually or every two years in early spring. Mature plants may only need repotting every 3-4 years or when root-bound. Use a good quality, free-draining potting mix.

Choose a pot only slightly larger than the current one to avoid excess moisture retention.
