Poisonous seed pods
Even on low-seeding 'Vossii', any pods that form are dangerous to children and pets. Remove seed pods and site away from play areas and grazing animals.
Short-lived and prone to dieback
Laburnums are not long-lived; branches can die back suddenly. Prune out dead wood in late summer to avoid bleeding sap.
Laburnum leaf miner and aphids
Leaf-mining moth larvae blister and brown the foliage, and aphids may cluster on shoot tips. Damage is usually cosmetic and rarely needs spraying.
