Abelia x grandiflora     Sp   Sm   Spring – shape up, remove longer branches.
                                   Summer – prune to shape after flowering (reduce 1 : 4 branches to near ground
                                   To renovate = cut all branches to base early spring.
Abutilon megapotamicum   Sp        Early / mid Spring – shape, remove crossing and overly long stems …
Aucuba japonica          Sp        Spring after display of winter berries. (If no berries then winter prune acceptable)
                                   Cut back lanky branches back to within body of plant. Otherwise trim branches
                                   over body of plant to maintain size / shape.
Bamboo                   Sp        Cut back old canes to ground floor level if clump becomes congested.
                                   Thin out as necessary through year. Remove overcrowded stems to ground level. If
                                   prune off top then will not regrow in height.

Brachyglotis             Sp   Sm   Mid-spring after frosts and prior to onset of new growth.
                                   These tend to put on a lot of growth over the year and can become leggy. Prune
                                   accordingly ie prune 1 in 3 back hard just above to new shoots.
                                   NOTE: flowers bourne on previous years growth in summer. Hard pruning
                                   therefore results in finer foliage effect at expense of flowers. Routine and sensible
                                   pruning should enable both!
                                   May also be pruned after flowering.
Buddleja davidii         Sp        Prune HARD early spring with the onset of new growth. (eg 20 / 30cm or 05 / 1m
                                   pending final required height)
                                   A prolific self seeder, therefore for ease, remove spent flowerheads promptly (may
                                   promote secondary flowering)

                                   Shorten over vigorous stems to balance future growth and to encourage a bushy
                                   Renovative pruning can be performed by hard pruning eg prune third of stems
                                   above ground floor per annum.
Carpinus betulus         Sp        Spring – prune as necessary.
Ceanothus dentatus       Sp   Sm   NOTE: pruning depends on whether flowering on new / old wood. Species
                                   Either spring prior to flowering if on new wood,
                                   Or Late summer after flowering if on old wood.
                                   DA suggest – trail / error – initial prune after flowering safer method – after
