The
Cox has developed a bit of a problem over the past few years. It is
prone to apple canker, which causes the branches to weep sap and turn
prematurely old and grey. The sap attracts woolly aphids, so you get a
sinister, fluffy white accretion on the affected branches.
Treatment
for the canker involves a regime of spraying, which I’m very reluctant
to embark upon. For the aphids, it involves taking an old toothbrush –
or the toothbrush of someone you don’t like all that much, dipping it
in a bottle of meths, and scrubbing the affected parts.
