Plant Care Tips
Daylilies are very easy to grow and need little maintenance. To help your plants do their best, plant them in full sun (or, in the case of darker-bloomed varieties where they will receive partial shade when it's really hot--this way the colour will not fade as much). While they grow in a wide range of soils, daylilies do best in well-drained, loose soil. Mulching (e.g. with wood chips or straw) can help improve your soil, will help retain water and will help control weeds.
Plant daylilies in the spring or fall, if possible. Once they're in the ground, water them regularly, particularly in spring, to help them establish. Though daylilies can withstand drought very well, they do not flower as well. It's best to give the plants a good deep watering (8-10 inches into the soil), or approximately 1 inch of water a week. Depending on your soil, you may want to use fertilizer once in spring, and, if you wish, again in the early fall.
Deadheading the plants each day will keep the plants looking great. Cut off the bloom scapes at the end of the blooming season. If you notice that the foliage is looking less than its best (e.g. after a long, hot summer), remove the damaged or diseased individual leaves or trim back the foliage to about 6-10 inches with clippers or a weedeater. If you can, leave the dead foliage through the winter or, if you want to tidy up your garden before the winter, mulch the plants well.
