- water frequency days Clemson HGIC ↗ Clemson HGIC "Summer- and Fall-Flowering Bulbs": "Glads need ample water throughout the growing season. Watering should soak the ground thoroughly. Avoid daily light watering." The factsheet publishes no interval; seven days is how often the app asks for that thorough soaking, not a published figure.
