Daylilies are hardy plants that thrive in well-drained soil, with a pH of 6.0 to 6.5 and light levels of full to partial sun. To plant them, dig a hole twice as wide and as deep as the daylily’s root ball, place the daylily in the hole, backfill it with soil, and water thoroughly.
Soil should be fertile, well-draining, and pH 6.0 to 6.5. The plant should be placed in the hole so the top of the root ball is level with the surrounding soil. Amend the soil with compost and a slow-release fertilizer, and gently firm the soil to remove air pockets.
For container-grown daylilies, dig a hole twice the diameter of the pot the plant is in, loosen the soil to a diameter of two feet, dig a hole about one foot deep, and then mound the soil up in the center. Place the crown on top of the mound, ensuring the crown ends up about one inch below the soil surface when the hole is filled in. Spread the roots out around the mounded soil.
When replanting divided daylilies, dig a hole and cover the root system with an inch or two of soil. If the daylily starts to produce fewer flowers, they probably need dividing. When planting a potted daylily, dig a hole that just covers the crown and is big enough for the roots and deep enough to cover the crown. The right size is about twice the diameter of the plant.

I have a huge day little Lily plants in my front garden which was established when I bought the house. It has grown perfectly every year with endless returning flowers as long as I deadhead. This year it is limp, all the flowers have died, and the only thing I can think is that I need to divide it. Is there any other reason you might think of that would cause this? Also, can they get too big? I don’t see that it’s much bigger than last year but maybe it is and once I divided it will come back?
