fashioned rose will have roses on a single
short stem. Deadheading roses will encourage
more flowers in repeat-flowering roses and
save others from forming seed.

The only exceptions are roses grown for their
hips (see Table 4.10); however, if they are
threatening to engulf the house or have
become too overcrowded they can be pruned
back very hard with no ill effect.
Climbing roses in this category (after pruning
at planting) need only weaving in the stems to
their support. Some can be trained through
trees. You may wish to do some minimal
pruning after flowering. Pruning to
rejuvenate these roses is best done just after
flowering. Many climbing once-flowered roses
such as
Rosa banksiae
can be pruned with a
chainsaw back to a main framework, and
removing some of the oldest wood to
encourage new canes. Do not remove too
much old wood as the flowers spring from
older (but not ancient) wood. This
reinvigorates the plant and it may be safely
left to its own devices for a few more years;
time enough to express their exuberant
personality!
The more sophisticated Gallicas, Moss,
Centifolias, Albas, Rugosas and Damask roses
are best lightly pruned after they have
flowered in much the same way as other
shrubs that flower once a year. As always,
remove any diseased, dead, damaged or
crossed stems. Some of the stems may look a
bit twiggy and weak; these can be thinned or
removed. If in doubt don't prune. As these
roses flower on buds formed in the previous
season, don't remove so much wood as to
reduce the leaf canopy too much. If you do,
