Watch out for

Cherry plum

It is a short-lived tree with brittle wood, and it shares the diseases of stone fruit: brown rot (Monilia) causes shoot dieback after flowering and fruit rot, and shot-hole disease, powdery mildew and gumming are common. Cut infected, withered twigs back to healthy wood and clear away fallen diseased leaves. Aphids and winter moth caterpillars attack it regularly. The bark of young trees can split in cold, sunny winters, so protecting the trunk in the first years is worthwhile.

Kousa dogwood

In the hot, dry summers of Central Europe the leaf edges scorch in full sun when the soil dries out, so mulch and water it. Chlorosis on alkaline soil and root rot in heavy wet clay can occur. Powdery mildew and leaf spots turn up, but it is far more disease resistant than flowering dogwood. Fallen ripe fruit is messy on paving and attracts wasps.
