Whack 'Em Back - Increasing Flowers by Pruning
Plants such as fuchsia and geraniums can be pruned back the end
of Februray to early March. The long lanky growth of winter's
low sunlight should be pruned back hard. This stringy growth is
not strong enough to support the weight of profuse summer
blossoms and unless the plant is cut back, this summer the plant
will look ugly when it should be a showpiece in your garden. I
used to simply whack the geraniums back to six or eight inch
stubs from their twelve to eighteen inch stems and allow them to
regrow and resprout from their stalks. Remember that the more
new growth you have on an annual plant, the more flowers it will
produce. Plants that have woody stems such as fuchsia should not
be so drastically pruned. Cut back leaving four to five side
side shoots to remain on the main stem. Each of the side shoots
can similarly be pruned back leaving only four or five leaves on
each of the side shoots.
Remember the cardinal rule of pruning. If you make a thinning
cut (a cut that takes a shoot off from where it started as a
bud) it will clear out and open up the plant. You will have
reduced shoots from a thinning cut. If you make a topping cut (a
cut anywhere else but where the shoot started as a bud) then you
will increase the number of shoots and growth. In annual
flowers, we use topping cuts to increase the number of shoots
and subsequent flowers.
Do use a sharp knife or garden pruners to make the cuts. Raggedly
cuts seem to heal slower and are, well - ugly. Sharp tools are
the mark of a good gardener and they are also much easier on
your hands. Dull tools are harder to cut with and lessen the
pleasure of gardening.
