Crab apples (Malus sylvestris John Downie""). These are popular garden trees and the tart little fruit can be used to make a jelly. The tree is a very useful pollinator for apple orchards and is used as a rootstock for cultivated apples. Two of the lower fruit show net like russeting from a powdery mildew (Podosphaera leuctricha) infection and the small dark spots are bitter pit, a calcium deficiency. Photographed in autumn, in the UK." | |
