If we get no rain we have to water our daylilies during the hot summer every 2 or 3 days, but thankfully less during the colder winter season. At first we watered using a garden hose and later with a sprinkler system. In the winter they are not growing, blooming or budding and require less water. If a freeze is coming we water which helps to protect the roots.
