Care | Caring for established orange daylilies is very simple. For the most part, this is a hands-off plant. Occasional pruning and dividing, as well as watering during prolonged dry spells, should do. |
Soil | Orange daylilies can grow in poor soils as long as they have good drainage. But they prefer an organically rich, moist soil. A slightly acidic to neutral soil pH is best. |
Water | Water young plants at least weekly to keep the soil moist but never soggy. After the first year, you likely won’t have to water your mature daylilies unless your area is going through a prolonged drought. But note that the plants prefer roughly an inch of water per week and will produce more blooms if they have optimal moisture. |
Temperature and Humidity | Orange daylilies have good tolerance for both heat and humidity. Frost will kill the foliage and cause them to go dormant in the fall. But they should survive through winter temperatures that drop well below freezing. |
Fertilizer | Because these plants are not picky when it comes to soil type, they don’t require fertilization unless you have very poor soil. If you do have poor soil, use a balanced fertilizer in the spring. For the amount to use, follow the product label instructions. |
Pruning | If all of the flowers on a flower stalk have bloomed, you can cut the whole stalk down to the ground to keep a tidy look. Feel free to remove any unsightly foliage or seed pods as well. |
Overwintering | As winter approaches, it is best to leave the foliage in place, allowing it to die off and remain on the ground. This will help to protect and insulate the roots over winter. Remove the plant debris in the early spring. |
