Pest identification
What's eating my sorbus hupehensis?
Rowan aphids (Dysaphis sorbi and allies)
Signs: Tightly rolled new leaves, sticky honeydew, sooty mold; stunted shoot extension
Control: Spray with insecticidal soap or neem oil early in the infestation; introduce or attract natural predators; remove worst-affected tips
Fireblight (Erwinia amylovora)
Signs: Flowers and young shoots collapse and turn brown-black; cankers spread into main branches
Control: Cut back 60 cm beyond visible infection; sterilize tools with bleach or alcohol between each cut; avoid lush, high-nitrogen growth
Pear sawfly (Caliroa cerasi)
Signs: Shiny, slimy larvae graze upper leaf surface leaving brown skeletal patches
Control: Hand-remove larvae; apply kaolin clay; pyrethrin spray for heavy infestations
Birds (fieldfares, redwings, waxwings)
Signs: Berries consumed from October onward, sometimes entirely stripped
Control: Wildlife value is high; accept or net selectively if needed

Sorbus hupehensis pests — FAQ
What is eating my sorbus hupehensis?
Sorbus hupehensis (Hubei rowan) faces the same pest range as other rowans: aphids distort new shoots, fireblight can kill branches, and sawfly larvae skeletonize leaves. Its distinctive white-pink berries are popular with birds. Fireblight is the most serious threat — prompt surgical pruning is the only reliable control.
