Daylilies come in low-growing, medium-height and tall-growing varieties, which means there is a variety for every part of your landscape. You will find them in almost every color except blue, and they multiply on their own. These perennials have been known to last year after year with very little care. There are varieties that bloom early in the season, mid-season or late season, so you can plant to have daylily flowers all season long.
Dig a hole in a location that gets full sun to partial shade. Pastel-colored daylilies will appreciate afternoon shade. The hole should be twice as deep as the bulb is long for low-growing and medium-height varieties, and a little deeper for the tall varieties. Spring is best for planting, but you can plant them anytime the ground is not frozen.
Space the bulbs 2-3 feet apart, as they will spread as they age and fill in the area between them. Mix a handful of compost to the dug-out soil and fill in the hole.
Water to keep the ground moist and establish roots. Do not leave them soaking or the bulb may rot. Once the bulb flowers, cut back water to once a week until the flowering season is over, and then stop watering until the following spring.
Fertilize the first time after flowering and then again in the spring and after flowering each year. Use an all-purpose flower fertilizer or one that is low in nitrogen.
Mulch with bark chips in late spring to help lock in moisture and keep the ground warmer during the winter. Daylily bulbs do not need to be taken out of the ground for winter.
