You Can Divide Daylilies Now

Daylilies are one of the most versatile flowering plants available to gardeners. You can depend on them to produce an abundance of showy flowers and the foliage makes a good ground cover. They are not attacked by insects and are susceptible to only a couple of mild disease organisms that don’t seem to hurt the plant very much at all. There are varieties available that will flower at different times during the growing season so that you can have Daylilies flowering most of the  summer. In addition to all of that, they are perennials meaning you don’t have to plant them over again each spring. In general, Daylilies don’t require as much maintenance as many other flowers.

If you noticed this year that your Daylilies didn’t  produce as many blooms as in the past, it is possible that they are starting to become over-crowded. After four or five years of growing in the same spot Daylilies tend to form a heavy mat of roots in the middle and the plant loses its vitality. To prevent this problem, divide your Daylilies frequently. Late summer and early fall is the ideal time of the year to do this.

These Daylilies are still doing fine and will not need to be divided for a couple of years.

Dividing Daylilies is very easy, all you need really need to do is dig the plants up and split them apart. With Daylilies it is easy to tell where the division should be made because they tend to form clumps of roots with a fan of leaves attached. Break these clumps apart and re-plant them into their bed or into a new spot. Place the clumps at the same depth as they were originally growing.

Many years ago I was asked to divide a relatively large bed of Daylilies. If I remember right my helper and I ended up transplanting somewhere around 2000 divisions.  We ended up constructing three more beds to hold all of them.  It did make a striking display.

If you have had no flowers at all from your Daylilies in the past, it is most likely there is a problem with the site. They do best in partial shade but will grow fine in a sunny spot if the soil is kept moist and has adequate fertility. Keep in mind however that they will not flower if they are planted in too shady of a spot.

Don’t be too concerned if you are unable to work on your Daylilies this fall, they can also be divided early next spring.
