Climbers that flower from last year's growth
Grapes, kiwifruit or Chinese gooseberry and
wisteria are members of this group but are
discussed separately below. These climbers
flower from buds formed the previous
growing season (see Table 4.23). Those that
do not form significant woody structures,
such as clematis and jasmine can be pruned
to within 30 cm of the ground after flowering
once they are established. The growth made
after this prune will carry the flowers for the
next season.
The each way bet
Some climbers are as generous as to flower
early in the season on last year's growth, as
well as blooming late on the current season's
growth (see Table 4.24). The dilemma is
whether to prune hard before spring and miss
the first flowering, or to prune after the first
flowering and miss the late summer show. In
many ways it is easier not to prune at all.
However, this strategy will eventually end in
tears; it won't be long before it resembles a
large bird nest rather than a purveyor of fine
flowers and foliage. Complete decapitation to
30 to 40 cm every few years is one option if
the climber will regrow from old wood.
However, this does not always suit the
management of evergreen climbers that have
been planted for screening purposes such as
jasmine. These vigorous vines can be hedged
back after flowering with great success.

Thin older stems in winter and remove spent flowering stems in

Alternatively, remove selected old flowered
branches, perhaps one or two a year, to renew
the flowering capacity and shorten back any
new growth straight after flowering.
