Softwood
cuttings are best carried out in April, May and
June from the mid-sections of strongly growing
vines. The tips will be too soft, and the lower
parts may be too woody.
Prepare 'cutting compost' in small
pots, firm down, and add a top layer of grit or
coarse sand. Water with a general purpose fungicide
and allow to drain.
Hygiene is paramount, so are fresh
rooting powder, a clean sharp blade and a container
with fungicide. Prepare the selected section of
vine by cutting through it immediately above a
leaf joint and again about 3-4cm below the same
node.
Remove the excess foliage: all of
one side (and part of the second side if there
are three leaflets or large leaves). This will
reduce moisture loss until the cuttings have rooted.
Completely immerse the prepared cuttings in fungicide
mixture, allow to drain, and then dip the base
of each cutting in rooting powder. Insert into
compost until the leaf joint is at grit level.
Label the pot and water it gently with fungicide.
Place in a well-lit area, but out of direct sunlight,
and maintain a humid atmosphere by covering with
polythene. (Use a propagator if you have one.)
Bottom heat of 20 deg C will aid rooting but is
not essential. Rooting should occur in four weeks.
Check by gently pulling on a leaf - if the
cutting moves, it is not rooted!
Pot up seperately when rooted, but
if they are not ready by late summer (late August
in the UK), delay the job until next spring. Grow
the cuttings on in pots for another year before
planting out.
