Rhus potaninii Potanin's sumac

Water

Rhus potaninii, also known as Korean sumac, should be watered once or twice each week depending on the climate and season. The best way to water is to give the plant a deep, thorough soaking until the soil is saturated. Allow the soil to dry out nearly completely between waterings, as Rhus potaninii is native to dry climates and can suffer if kept too wet. During hot, dry weather, it may need more frequent watering. Rhus potaninii requires an average of 1 to 1.5 inches of water per week.

Light

Rhus potaninii thrives in full sun to part shade conditions with bright, indirect light. The best spot for this plant is an area with morning sun and afternoon shade or bright, filtered sunlight throughout the day.

Temperature

The best lighting conditions for Rhus potaninii is at least 6 hours of direct sunlight each day. This should be supplemented with shade during the hottest hours of the day. For the best summer temperature conditions, the ideal range for Rhus potaninii is between 59-77°F (15-25°C). In the winter, the ideal range for this species is between 41-59°F (5-15°C).

Pruning

Rhus potaninii should be pruned in late winter or early spring before new growth begins. The amount of pruning depends on the desired size and shape of the shrub. If a strong form and dense foliage is desired, prune the shrub heavily; remove at least one third of the foliage and the oldest, thickest stems. If the desired shape is open and loose, prune out only the old, dead stems and a few slender crossed ones. Avoid topping the plant with a flat surface.

Soil

instructions Ingredients needed: 1. 3 parts peat moss 2. 3 parts plastic potting soil 3. 1 part perlite 4. 1 part horticultural sand Instructions: 1. Begin by combining the peat moss, plastic potting soil, perlite and horticultural sand together in a large bucket. 2. Thoroughly mix the ingredients to make sure they are evenly distributed. 3. Place the soil mixture into your pot or other planting vessel and gently tamp down. 4. Water the soil mix until it is evenly moist. 5. The soil pH should be slightly acidic, ranging within the range of 4.5 to 6.5. For best results, consider testing soil pH prior to use. 6. Plant your Rhus potaninii in the prepared soil mix and water to settle the soil around the roots.

Repotting

No, Rhus potaninii does not need to be repotted.

Humidity & Misting

The best humidity level for Rhus potaninii is between 40%-60%. To increase the humidity, mist the leaves with water several times a day, keep the plant near a humidifier, or place it on a tray of wet pebbles. To decrease the humidity, keep the plant away from air conditioners and radiators and ensure the soil isn’t overly wet.

Suitable locations

• Indoor

  Rhus potaninii prefers bright, indirect light, moist but well-drained soil, and temperatures between 65-75°F. The soil should also remain consistently moist, and should be fertilized with a balanced, water-soluble fertilizer every two weeks during the plant’s growing season (spring to early fall). Rhus potaninii can tolerate lower light levels but will not flower in dim conditions. When the plant is actively growing, it should be kept at a minimum of 6 feet away from any cold drafts and heated vents. During the winter months, Rhus potaninii should be placed in a cool area with temperatures between 45-55°F and kept away from major temperature fluctuations. The soil should remain barely moist during the winter months, with just enough water to keep the soil from drying out completely.

• Outdoor

  Rhus potaninii grows best in full sun to partial shade, in moist (but well drained) soil exposed to temperatures ranging from 40 to 85 degrees Fahrenheit. It prefers high humidity and occasionally moist soil. It also thrives in a location not too far from a source of water for irrigation, such as a pond, stream, or lake. Rhus potaninii prefers a soil pH range of 5.5 to 7.6 and does best when planted in a location that does not receive too much wind. It has an average growth rate, typically reaching a height of anywhere from 3 to 8 feet tall and a spread of up to 6 feet.

Life cycle

. Rhus potaninii, commonly known as Korean burning bush or winged sumac, is a deciduous, shrub-like plant native to Eastern and Central Asia. It features large, velvety, light green leaves that turn a deep burgundy shade in the fall. In the summer, clusters of bright red berries form that persist into the fall and winter. Germination: When grown from seed, Rhus potaninii starts to germinate in the late spring when soil temperatures reach at least 70°F. Seedling: In its early stages of growth, Rhus potaninii forms a small, rounded shrub with an upright stature. The leaves are bright green and offset by red berries. Maturity: As Rhus potaninii continues to mature, its foliage darkens and becomes shaggy in its appearance. The shrub is typically 3-6 feet tall and 4-6 feet wide when fully mature. Reproduction: In the late summer, Rhus potaninii produces clusters of shiny, red berries. The berries persist throughout the winter, providing food for many wildlife species. Senescence: Rhus potaninii typically lives for 15-20 years. As the shrub ages, its leaves turn a deep burgundy shade in the fall and its growth rate slows. It can reach a height of up to 9 feet.

Propogation

• Propagation of Rhus potaninii can occur through stem cuttings or through division of a clump. Stem Cuttings: Rhus potaninii can be propagated through stem cuttings taken in late spring. Stems should be taken from the current or previous season's growth and trimmed to 3-4 inches in length. Under ideal conditions, the cuttings should form a callus within 2-3 weeks after being removed from the mother plant. The cuttings should then be individually potted up in a quality potting mix and placed in a unheated greenhouse (50-60°F) with bright, indirect light. Water the potting mix well and keep it evenly moist for the first month, after which the rooting process should be complete. The plants can then be fertilised every 6 weeks during spring and summer months. Clump Division: Rhus potaninii can also be propagated from division of an established clump. The clumps should be carefully dug up and divided into smaller sections when the soil is moist. Each portion should have a decent amount of roots attached to it and should then be individually potted up and placed in a unheated greenhouse (50-60°F) with bright, indirect light. As with the stem cuttings, the potting mix should be kept moist during the rooting process (approximately 2 weeks) and the plants should be fertilised every 6 weeks during the spring and summer months.
