The best time to plant daylilies is in spring or autumn, but if you buy
container-grown plants you can plant them out any time during the growing season. Just avoid periods of drought,
unless you are prepared to water your new plants faithfully.
Improve your soil by working in some compost in before planting. Recommended planting distance is 50 to 60 cm
apart. Your planting hole should be a little larger than the root mass.
The crown (band of white on the foliage) is the indicator for depth as this should be just below the surface. Set
the plant so that the crown is no deeper than inch below the surface of the soil.
Correct depth:
Firm the soil after planting, using your hands (pressing or stomping with your feet can cause root damage).
Watering:
Water plants thoroughly after planting, and continue to deep soak them at least
weekly until established (about six to eight weeks). Although daylilies are drought-tolerant once established,
consistent watering while they are budding and flowering will produce better-quality flowers.
Mulching and fertilizing:
Mulch your daylily beds with compost in spring. Avoid giving
daylilies high nitrogen fertilizers as this promotes more foliage growth at the expense of flowers. Fertilizers
with 5-10-15 and 6-12-12 are low in nitrogen and provide good ratios of phosphorous and potash.
