SPRING                                                                    Details
Abelia x grandiflora     Sp   Sm   Spring – shape up, remove longer branches.
                                   Summer – prune to shape after flowering (reduce 1 : 4 branches to near ground
                                   level)
                                   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.
Bergenia cordifolia      Sp        Flowers over winter/ spring. Remove dead leaves as necessary eg spring
Betula                   Sp        Prune out dead / damaged / diseased branches. Prune crown only if overgrown.
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)
Callicarpa               Sp        Early spring after frost but whilst plant is still dormant.
Camellia japonica        Sp        Spring, after flowering but before growth buds break.
                                   Shorten over vigorous stems to balance future growth and to encourage a bushy
                                   plant.
                                   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
                                   dependant.
                                   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
                                   flowering mid summer
Chaenomeles              Sp   Sm   Late spring /early summer after flowering. Show a fair degree of growth over the
                                   season so prune back accordingly eg reduce circa 5 / 6 shoots on all stems.
                                   Thin out main body of crossing stems.
Choisya ternata          Sp        Spring after flowering and may get 2nd flush in Autumn. Hard pruning in spring
                                   (immediately after flowering) is best for well grown species.

Clematis Montana         Sp   Sm   Very dependant on species.
                                   Eg. Spring flowering – flower on last seasons growth in spring - prune after

                                   Other (majority) = investigate type as either flower on previous or current seasons
                                   growth – safest option = prune after flowering. Potential to cut back hard.

                                   Allow to develop initially before pruning, followed by simple pruning of overly
