However, if you wish to shape or control its growth, pruning can be done during late winter or early spring before the new growth begins. Avoid pruning during the growing season, as it can lead to reduced vigor and flowering.
Propagation Methods for Rhus aromatica Ait. var. flabelliformis Shinners
Propagation of Rhus aromatica Ait. var. flabelliformis Shinners can be done through various methods such as seed propagation, softwood cuttings, and sucker divisions.
Seed Propagation
Seeds can be collected from the Rhus aromatica Ait. var. flabelliformis Shinners plant and used for propagation. Collect ripe fruits from the plant and remove the pulp by washing in water. Dry these seeds and store for later use or use them immediately. Sow the seeds in a well-draining soil mix and keep them moist until germination. Germination can take up to 2 months, and seedlings can be transplanted once they are large enough to handle.
Softwood Cuttings
Softwood cuttings are taken from the plant's new growth, and this method is best done in the spring or early summer. Take cuttings that are 3-4 inches long, remove the bottom leaves, and dip them in rooting hormone. Insert the cuttings in a well-draining soil mix and water appropriately. Cover the cuttings and keep them in a warm place with bright, indirect light. Remove the cover once the cuttings have rooted and have started to produce new growth.
Sucker Division
Rhus aromatica Ait. var. flabelliformis Shinners produces suckers that can be used for propagation. These suckers can be removed from the parent plant and planted in a well-draining soil mix. Water appropriately and keep the plant in a warm place with bright, indirect light. The suckers will develop roots and can be transplanted to a permanent location once they are large enough to handle.

Also, ensure that the plant is well-ventilated and avoid overhead watering as it can encourage the spread of disease.
Powdery Mildew: Powdery mildew is a fungal infection that affects many plants and is identified as a white or gray powdery substance on the leaves. It can lead to stunted growth and distorted leaves. To manage powdery mildew, avoid overhead watering, and ensure that the plant gets enough sunlight and air circulation. Remove any infected leaves and dispose of them properly. You can also apply fungicides to prevent further infection.
Common Pests
Japanese Beetle: These are small, metallic green beetles that can cause severe damage to the leaves of Rhus aromatica Ait. var. flabelliformis Shinners. Handpicking them off the plant is a useful method to control their population. You can also place sticky traps around the area and apply insecticides to mitigate their population.
Scale Insects: These insects are small and resemble little bumps on the leaves or stems of the plant. They feed on the sap of the plant and cause the leaves to yellow and eventually fall. To manage scale insects, prune all parts of the plant that are severely infected and dispose of them properly. You can also use horticultural oils to coat the affected areas and prevent further infestation.
In conclusion, proper disease and pest management practices are essential to ensure the healthy growth of Rhus aromatica Ait. var. flabelliformis Shinners. Timely detection, intervention, and continuous monitoring can save the plant from severe damage and prevent the spread of disease and pests.
