Root divisions are created when multi-stemmed plants are pulled apart to form single stems. Daylilies are vigorous growers and often used as ground cover. They will spread and form a dense mat after a few seasons.
Daylilies planted in the shade will bloom less frequently.
To amend soil that drains poorly, add some organic matter like well-rotted manure, wood chips, pea gravel, or peat moss. Mix it into the existing soil thoroughly.
To reduce acidity in your soil, add garden limestone. To reduce alkalinity, amend the soil with sulfur, gypsum, or sphagnum peat moss. [5] X Research source
Daylilies are perennials, which means they go dormant during winter and then come back each spring.
The organic matter in compost and manure encourages copious blooming and helps the soil retain moisture.
If the hole needs to be adjusted for the crown, pull out the division and amend the hole as needed. Each root division will have 2 to 3 stems.
Packing down the soil may reduce soil drainage around the plant.
If you plan to divide your plants during the next season, planting them 2 ft (61 cm) apart is fine. If you don’t want to divide them, give them about 3 ft (91 cm) of space.
Over-watering can cause crown rot, so be careful. Avoid watering daylilies during the midday heat.
Straw, grass clippings, and leaves are all good choices for mulch. Summer mulching helps the soil retain water and lowers the soil temperature during the hot summer days. Mulch also helps crowd out weeds. [15] X Research source
If the mites are particularly tenacious, you can also use an insecticide. [16] X Research source
Only choose your healthiest daylilies for division. Cutting back the foliage helps the roots establish themselves more easily when replanted.
Make sure that the crown isn’t too deep. Replanting that way can cause the crown to rot. The daylilies will grow and fill in the new space around them.
