How to Grow Daylilies – A Growing Guide
Daylilies are one of the strongest and most adaptable perennials on the planet. They are hardy and strong in zones 3-9. They endure full sun but are known to adapt to mostly shade. They also tolerate most soil conditions. Also they virtually have not problems with diseases or pests. These plants want to live they bloom strong for most of their lives and there are many types that are re-bloomers throughout the season.
Daylilies are very versatile and have many different shapes and sizes because of this daylilies are well-suited to many different places in the garden and landscape. The smaller varieties tend to work well planted directly into perennial borders, where they can help complete the picture but are not the star of the show. while the large ones perform well as the center piece of your garden or landscape. Another place that is perfect for daylilies is along the edges of a fence row, a driveway, or a yard, there they will serve as a beautiful boarder and really set a tone of beauty where they are planted.
Daylilies perform best when planted in full sun, on moist, well-drained soil(although once established they are drought resistant. However these plants are vary adaptable and over a few years will adjust to most shaded areas, as long as they are still getting a little bit of sun. In hot climates, dark-colored lilies should receive some afternoon shade to help the color stay vibrant. When planted in the right spot, daylilies flower for years with little attention from the gardener. They do not require fertilization although you may want to add compost annually.
If you order bare-root daylilies they should be planted within 1-3 days to avoid transplant shock, and to get the healthiest, and most beautiful production from the plants. These plants can be planted almost year round, and be fine, however they do have preferences about when they want to be planted, and tend to do a little bit better if planted during those times of preference. In the South, for the best results plant in the spring or fall while the temperatures are low. In the North, late spring and summer tend to be better times so they have time to really get established before the winter. But as I said before daylilies want to live and are usually fine to plant year round.
For planting make sure you work the soil with compost before putting the roots in. Space plants 12 to 18 inches apart and plant so the crown is about 1 inch below the soil surface. These plants do from clumps and need this space to grow them. Water well and mulch to conserve moisture and it will also help stop weeds from growing. These plants are very strong but while young should be weeded so they can get well established.
Daylilies have very few issues. They can occasionally develop rust to avoid this water well and trim and infected foliage.
One of the few routine things that should be done with daylilies is dividing their clumps. If clumps get too tight is can effect the amount of flowers they produce, usually ever 3-5 year a clump will need to be divided. In most places, late summer, is the best time to divide daylilies, so you don’t miss any blooms, but you really can divide them at almost any time of the year. In the North, early spring probably the best time, but really you should make sure to avoid dividing them in the winter.
To divide the clumps dig up each clump, and use a sharp knife or other tool to separate healthy young fans with strong, and large root systems. Trim the foliage and replant immediately in new soil or container, or throw them out if you don’t want the new daylilies. You will have plenty of extra plants from each clump to give away to friends. Get rid of any small or diseased plants.
If you are far up north, a layer of mulch in late fall, is always a good idea. This is important for young plants so they can be preserved until they can get better established. Dead surface foliage, can be removed in the spring however if it is diseased remove it immediately.
