Gardening Questions And Answers
Soil Type. Like most perennials, daylilies prefer rich, well drained soil that has good aeration. If your soil is too sandy or is heavy clay add compost to make it more daylily friendly. High quality daylilies will perform in most soil conditions but to get the best growth and bloom build up the quality of […]
Daylilies are easy to grow and care for, perennial, and drought-tolerant. Learn how to grow them in your garden and landscape. Plant daylilies in spring or fall when the weather is mild. Water plants thoroughly at the time of planting and throughout the season if your region is experiencing drought.
Daylilies can be planted year-round in some USDA zones, but the best planting times in all zones are spring and fall. In areas that never experience frosts, daylilies can be planted in pots any time of year, but planting in spring or fall allows the plants time to establish good root systems before flowering.
To propagate them, divide the daylily clumps in early spring (February through April) or in the late summer to fall after flowering (late July through mid-September). Often, the Autumnal Equinox is considered the last possible day for dividing. The plants need at least six weeks to get re-established before winter.
Most commonly, your plant may not be receiving adequate amounts of sunlight in the garden. As the plants grow and multiply, the daylilies may have to compete for space and nutrients in the soil. This often results in diminished size of the plant, as well as a decrease in the number of flowers that are […]
Many varieties are happy in Zones 4-11, which is a larger range than most perennials. Daylilies are very cold-hardy, as well as heat-tolerant. On top of being adaptable to temperature ranges, they thrive in a wide variety of climates. They’re a great choice for hot, dry climates, as well as cool, moist ones.
Soft Rot: Pectobacterium carotovorum causes bacterial rot at the base of daylily flowers and in their rhizomes. This bacterium that causes soft rot is a common soil inhabitant. High temperatures, poor air circulation, poor soil drainage, and improper fertilization all favor soft rot disease development.
Mulching: Daylilies like many other herbaceous perennials like to be mulched with wood chips, straw, leaf mulch or compost materials. Mulch will improve moisture retention, soil tilth, buffer effects of freezing and thawing and control weeds. After planting a bed, apply a two-inch layer of organic material.
Most daylilies bloom best in full sun. They will tolerate part shade conditions, but require a minimum of six hours of direct sun per day. Many red and purple varieties benefit from partial shade in the hottest part of the day since dark colors absorb heat and do not withstand the sun as well as […]
Planting Care Daylilies flower best when planted in full sun (6 hours/day), on moist, yet well-drained soil. In hot climates, dark-colored cultivars should receive some afternoon shade to help them retain their flower color. When planted in the correct location, daylilies will flower for years with little care.
When aphids deplete the sap, daylilies begin to weaken. This leads to wilting, curling foliage, yellow leaves and stunted plant growth. To make matters worse, ants flock to the honeydew for feeding, leading to further plant damage. If you see a trail of ants around your daylilies, look for colonies of aphids.
