|How do I prune punica granatum, westringia fruticosa, and salvia clevelandii?
|Punica granatum, the pomegranate, generally does not require much pruning. Prune only to shape young plants or to restrain the tall growth of older ones. Pruning should be done in early spring before new growth starts so that the current season's stems can produce flowers.
Westringia fruticosa, also known as the Coastal Rosemary, responds well to a light shearing in early spring, just as new growth begins. This plant can be cut back by one-third if it is getting woody or leggy, or if it suffers winter damage.
Salvia clevelandii, or Cleveland Sage, will become overgrown in a hurry if not pruned back. Pruning is best done in two stages: a third off the stems in the fall, and another half of what's left in winter. This will help keep a more manageable shape.
