Watch out for

Firethorn
In Central Europe two diseases really matter. Scab blackens leaves and berries, and older varieties can lose much of their foliage by late summer. Fire blight (Erwinia amylovora) is a dangerous bacterial disease: shoot tips suddenly turn brown as if scorched, and the infection can spread to apple, pear and quince, so near fruit trees plant only resistant varieties. In hard winters without snow cover the foliage may brown or partly drop and shoots can die back, but the shrub usually resprouts in spring. Firethorn leaf miner and aphids may appear on the leaves; they are mostly cosmetic.
Holly osmanthus
In Central Europe it is at the edge of its hardiness: it is reliable down to about -18 °C, and in colder winters, especially in windy, sunny, exposed spots, the leaves scorch and shoots die back, although it usually resprouts in spring. Protect young plants with mulch and a cover in their first winters, and avoid frost pockets. Variegated cultivars are more tender. Pests are few: scale, aphids and occasionally vine weevil.
