Annual Agoseris

Annual Agoseris (Agoseris heterophylla) should be watered regularly to keep the soil consistently moist, but not soggy. The amount and frequency of watering depend on the soil and climate. During the warmer months, water the plant deeply once per week or more often if the soil starts to dry out between waterings. In the heat of summer, water twice per week. During the cooler months, water deeply once every 2 weeks or more if the soil starts to dry out. Check the soil by sticking your finger in about 1 inch deep, and if it feels dry, it's time to water.

Annual Agoseris (Agoseris heterophylla) does best in full sun or light shade and requires at least 6 hours of direct sunlight per day. This plant species grows best during the spring and summer months and should receive full sun for the entire available duration. For example, if the sun is out for 8 hours, the Agoseris should be exposed to direct sunlight for 8 hours. It will tolerate some light shade during the afternoons in the hottest parts of the season. Avoid placing the Agoseris in full shade, as this will reduce flowering and overall growth.

Annual Agoseris (Agoseris heterophylla) is best pruned in early spring before new growth begins. Because it is an annual, it does not need to be pruned heavily - just enough to minimize overcrowding and keep the plant looking full and healthy. Remove any old or dead foliage, as well as any stems that are starting to become leggy. If the plant is becoming overgrown, it may be necessary to cut back some of the stems by up to a third of its length. Doing so will help the plant to produce more blooms and promote an overall attractive appearance.
