SOIL pH: A pH range of 6.0-6.5 is ideal for daylilies. An application of lime may be needed should the pH range fall below 5.5. A soil analysis is the best means of determining the need and the amount of lime to apply.
SOIL REQUIREMENTS: Daylilies will grow in a variety of soils ranging from light sandy types of heavy clays. Areas used for daylilies should be spaded or tilled deeply to improve the physical condition. Improve clay soil by thoroughly blending in coarse sand and organic material. An indication of a good soil is one that has plenty of earthworms.
PLANTING: Plant after the last spring frost and six weeks prior to the first winter frost. Plant barefoot arrivals as soon as possible. We like to put new daylilies in water with Miracle-Gro Quick Start when we can't plant them the next day. (Follow instructions on box). Keep the soil several inches wider than the root system and at least a foot deep. The soil should be worked before replacing it around the roots. Construct a cone-like mound of soil in the bottom middle of the planting hole. Set the plant with roots spread over the top of the mound and trailing downward. A safe rule is to set the plant so that crown (the point where roots and foliage meet) is no deeper that one inch below the surface of the soil or even with the soil line. Construct a small mound of soil around the outside of the planting hole with the remaining soil to aid in directing water toward the root system when irrigating the plant. Water the plant thoroughly after planting and once or twice a week until well established.
MULCHING: Mulching that settles to about 2 inches deep will retain water during hot summer weather, maintain cooler soil temperatures, control weeds and increase water penetration. Materials such as pine straw, pine bark, wood chips and decomposed leaves provide effective mulch.
FERTILIZING: Fertilize after the last frost, during peak bloom season, and in the fall. Apply fertilizer only to the base of the plant and water in.
KEEPING OUT INSECTS: You can plant numerous host plants for beneficial insects and birds including: green lacewings: angelica, red cosmos, goldenrod, Queen Anne's lace, tansy, baby blue eyes, cosmos, Gloriosa daisies, marigold, Meadow foam (Linnanthes Douglasii), spearmint, butterfly weed, euonymus, tansy, yarrow, raspberries and other brambles, anise, caraway, catnip, coriander, cumin, dill, fennel, lavender, sweet marjoram, mint, rosemary, autumn and pineapple sage, and thyme.
