Moss, commonly misunderstood as merely harmless, can densely colonize the surface of Skunk-bush sumac, impeding photosynthesis, nutrient absorption, and eventually harming the plant's overall health.

Leaf yellowing on Skunk-bush sumac typically indicates a distress response, impacting photosynthesis and growth. This general symptom can be caused by various factors ranging from nutrient deficiencies to diseases.

Scale insects are pests that attach to the leaves and stems of Skunk-bush sumac, causing yellowing, leaf drop, and stunted growth. The infestation can weaken the plant significantly if not controlled.

Spider mite infestation can severely affect Skunk-bush sumac, leading to discoloration and leaf loss. The infestation peaks in warm, dry conditions, and can severely stunt plant growth if uncontrolled.

Yellow edges is a condition affecting Skunk-bush sumac, characterized by the yellow discoloration of leaf margins. It can reduce aesthetic value and overall vigor of the plant but is generally manageable with proper care.

Aphids are pests that target and damage Skunk-bush sumac, leading to decreased vigor and potential death. They suck sap from plants, leading to stunted growth, curled leaves, and can spread viruses.

Leaf beetle disease primarily affects Skunk-bush sumac, causing significant defoliation that can weaken the plant. It typically leads to decreased vigor and aesthetic decline.

Lichen disease, though not a true pathogenic condition, appears as a symbiotic relationship between fungi and algae, often manifesting on Skunk-bush sumac by affecting its photosynthesis and aesthetic value.
