Watch out for

English oak

Since the 2010s the oak lace bug, introduced from North America, has caused mass damage in Central Europe: leaves fade and yellow by midsummer and drop early, and the insects may swarm over house walls and terraces; there is no effective control yet. The stinging hairs of oak processionary moth caterpillars cause severe skin rashes and breathing problems, and nests should be removed by professionals only. Powdery mildew is common on young shoots. Old trees suffer from falling groundwater levels and prolonged drought and may die back.

Red oak

On calcareous, alkaline soil it develops iron chlorosis (leaves yellow while the veins stay green) and declines, so it does not suit lime-rich gardens in Central Europe. It is a North American species that spreads by seed in Central European forests and smothers the ground flora with its slowly decaying leaf litter: Germany officially classifies it as invasive and it is on the Czech black list, so do not plant it next to woodland or semi-natural areas. The thick, slow-rotting leaf litter and the many acorns mean work in the garden too, and it does not like being under solid paving. Caterpillars (gypsy moth, for example) sometimes strip the leaves.
