watering

Culver’s root requires average amounts of water and thrives in moist soil. During the summer months, water the plant deeply once or twice a week, providing enough water for it to reach the roots. During dry summer spells, increase the frequency and amount of water. During the winter months, water once or twice a month, allowing the soil to dry out slightly between waterings.

sunlight

Culver's root requires full sun for at least 6 to 8 hours a day for optimal growth. Direct sunshine should be provided from morning until late afternoon, typically from 9:00 am to 4:00 pm. If planted in a location that receives less than 6 hours of direct sun, the flowering and overall growth of the plant may be diminished. Additionally, the amount of sunlight needed may vary by season or climate, so choosing a site that receives sun for the entirety of the growing season is important.

pruning

Culver's root should be pruned in the spring or fall. During the winter, pruning should be minimal and only focused on removing any dead or damaged stems. When pruning in the spring, remove any stems that appear to be overwintering poorly, as well as any that are crossing or rubbing against each other. In the fall, prune to control the size and shape of the plant. Avoid pruning more than 1-third of the total stems and branches, as this can cause the plant to become lopsided. Additionally, avoid pruning too severely in any 1 year, as this can weaken the plant.
