watering
The obedient plant needs to be watered frequently during the growing season, ideally on a regular basis - about 1 to 2 times a week - and more during hot or dry conditions. A deep weekly soaking is better than frequent shallow waterings, as the plant does better with more moisture in the soil. During the cooler months, it's best to water the obedient plant only when the top inch or 2 of soil is dry. Depending on the region and climate, this could range from once or twice a month during the winter months to once a week if it's mild. Be sure to adjust the frequency accordingly.
sunlight
Obedient plant (Physostegia angustifolia) thrives in areas of full sun, meaning it needs at least 6 to 8 hours of direct sunlight every day. However, if your obedient plant starts to wilt too quickly in the intense afternoon sun, providing afternoon shade can help protect it from becoming excessively sunburnt. At the same time, if your plant is not receiving enough light, you might consider giving it a few more hours of sunlight. Since obedient plant is native to the southeastern United States, it does best with an ample amount of sunlight exposure during the summer months. During the winter, light may be more limited and the plant should receive at least 1-3 hours of partial sunlight per day. If an obedient plant is not getting enough sunlight, its leaves may begin to yellow and the stems may become more compact.
pruning
The obedient plant (Physostegia angustifolia) is a low-maintenance plant species that usually only requires pruning once every 2-3 years. Pruning should be done in the late winter/early spring. It is best to cut off any dead or wilted stems at ground level. If the plant has become too large, then the taller stems can be cut back, but removing more than 1-third of the plant will harm the growth of the plant. If the plant is used as a border in a landscape, it can be regularly trimmed to keep it neat and tidy. Make sure to use sharp pruning shears and gloves when handling the plant.
