watering

False gromwell should be watered 1 to 2 times per week, making sure to water deeply in order to bring water to the root system. The amount of water used should be adjusted according to the weather conditions and the time of year–in the heat of summer, more water should be used than in spring or fall. When watering, it's best to provide an even soaking. Avoid wetting the foliage of the plant except in times of extreme heat and drought.

sunlight

False gromwell (Onosmodium molle) needs at least 6 hours of direct sunlight per day. It needs the sunniest spot in the garden, so it should be placed in an open location with full sun exposure all day long. Always rotate the pot of false gromwell occasionally to ensure all sides of the plant get equal exposure to the sunlight. False gromwell thrives in temperatures between 35-90 degrees Fahrenheit and should not be exposed to prolonged temperatures anywhere close to freezing. If grown in containers, keep false gromwell in a bigger pot than what was previously used because these plants spread and grow fast. When planting false gromwell outdoors, plant them in an area that receives sunlight for the majority of the day.

pruning

False gromwell should be pruned in late winter or early spring. Generally, pruning should not take more than 1-third of the total canopy of the plant. Pruning is not necessary, as flowers are borne at the tips of the stems and along the sides of the stems. The main goal of pruning false gromwell is to promote bushier growth and to minimize weeds and disease. If any diseased or dead branches are present, they should be removed when pruning.
