watering

Tetraploid daylilies (Hemerocallis 'Crown Royal') should be watered deeply about once a week, especially during the first few weeks after planting. The soil should be kept moist, but not soggy. During the hottest and driest months of summer, daylilies may need to be watered 2 to 3 times a week. Watering in the early morning will ensure that the plants do not receive too much extreme heat and dryness during the day. During cooler months, reduce watering as needed to match the natural precipitation.

sunlight

Tetraploid daylilies (Hemerocallis 'Crown Royal') need between 4 and 6 hours of direct sunlight each day for proper growth. They thrive best in sunny spots with 6 hours of sun and can still flower in as little as 4 hours of sun. When planted in shady locations, the plant will tend to produce fewer flowers and fail to thrive as well. For optimal blooms, plant Tetraploid daylilies (Hemerocallis 'Crown Royal') in an area that receives at least 6 hours of direct sunlight per day.

pruning

Tetraploid daylily (Hemerocallis 'Crown Royal') benefits from being pruned or deadheaded regularly to prevent the plant from becoming overgrown and to encourage healthy growth and bloom. Pruning should be done as soon as the flowers begin to fade in late summer or early fall. It is best to remove the faded blossoms along with the foliage around them as this will allow new buds to develop at the base of the plant. If only the dead blossoms are removed, they will continue to grow, but they will not produce new buds. When pruning the foliage, it is important to only prune off the tips of the foliage, not the entire length of the foliage. This will help to maintain a fuller and healthier plant.
