Daylilies form clumps that can be divided when necessary, with healthy roots and a suitable planting position helping new divisions establish. Keep the divisions from drying out while preparing their new planting places.
Divide a daylily for a clear purpose
Hemerocallis clumps can become congested, but shade or weak establishment can also limit flowers. Keep the cultivar label and inspect the plant before splitting it. A recently moved clump may need time rather than another disturbance.
Retain sound fans and roots
Divide healthy material at a suitable local stage and keep enough roots and living growth on each section. Remove decayed portions appropriately. Making the smallest possible pieces can delay recovery and flowering.
Replant at the appropriate level
Use suitable soil or container compost, spread roots sensibly and water in as required. Keep drainage workable and do not bury crowns indiscriminately. Check the original root area while divisions establish.
Support the next growth cycle
Provide appropriate light and consistent root moisture during establishment. Retain useful leaves after flowering. Feed according to healthy activity and soil conditions; concentrated fertilizer cannot guarantee an immediate full display from small or damaged divisions.
