Don’t prune now
Silver-leaved plants such as Convolvulus cneorum are less hardy. Leave unpruned until late March; the top growth will insulate them from frost.
Fruiting and ornamental cherries, as well as plums and damsons, should not be pruned in winter to reduce the risk of silver leaf disease.
Japanese maples are among a small group of plants that bleed sap easily. Prune in autumn when less sap is flowing.
Ornamental grasses are best cut back when they start into growth in early spring.
