watering
Oxeye sunflower should be watered when the soil 1-2 inches deep is slightly dry to the touch. A general rule of thumb is to water oxeye sunflower deeply and thoroughly approximately once per week. In warmer climates, water more frequently than once per week. To ensure that the entire root system receives water, thoroughly saturate the soil surrounding the plant. When watering, ensure that the entire root ball is moistened throughout. After watering, check the soil 1-2 inches down to make sure the soil is retaining moisture.
sunlight
Oxeye sunflower (Heliopsis helianthoides) should be grown in a location that provides full sun to light shade, meaning the plant should receive at least 6 to 8 hours of direct sunlight each day. This species of sunflower is fairly tolerant of partial shade, but the more sunlight it receives, the better. Morning sunlight is the most beneficial since it helps the plant dry off any leftover moisture from the night before. Oxeye sunflower should not be planted in a shady area, as it will struggle to survive in that environment.
pruning
Oxeye sunflower should be pruned in late winter or early spring before new growth begins. Pruning can help maintain the natural shape of the plant, encourage flowers to form, and prevent the plant from becoming overgrown and unruly. For general maintenance, prune back dead flower heads and any dead branches. For fuller, bushier flowers and plants, lightly prune outer stems back by 1/3 every spring. Additionally, plants can be divided every few years to encourage healthy growth.
