What's eating my begonia 'pin up flame'?

Tuberous Begonia 'Pin Up Flame' faces vine weevil larvae attacking tubers, aphids clustering on buds, and slugs damaging petals at ground level. Deer and rabbits may browse unprotected plants in open garden settings. Vine weevil root damage is the most serious and hardest-to-detect threat to this cultivar.

Sudden wilting; tubers and roots hollowed or severed by white grubs in the potting mix Drench with Steinernema kraussei nematodes in late summer; repot annually inspecting for grubs; use vine weevil-treated compost

Sticky residue and distorted buds; dense colonies of green or black insects on soft shoot tips Spray with insecticidal soap or a dilute neem oil solution; repeat weekly until clear; avoid over-feeding with nitrogen

Holes in large petals and lower leaves; mucus trails around the base of the plant Iron phosphate pellets placed around plants; remove hiding spots such as dense ground cover; water in the morning so soil dries by evening
