How much should I water Daylilies?

Water every three days during the dry season and every day for those in containers. Daylilies benefit most from a deep watering, reaching 8 to 10 inches into the soil, rather than a surface watering. Be alert, though, that overhead watering during the heat of the day can cause open blooms to spot and/or wilt. Also, be careful to maintain good drainage and not over-water.
