This type of growth form is really only
practical for the greenhouse owner, if the larger specimens are to be
constructed, as it is usual for the first season to be devoted to
developing a strong, straight, stem or trunk and the commencement of
the flowering head. It is rarely possible to produce a full standard
in one season even when using the most vigorous of cultivars. The
second season will achieve the full size of head, developing a depth
and diameter in proportion to its overall height.
For show purposes the BFS requirement for a
full stan dard is a clear stem of not less than 30 inches and of not
more than 42 inches from soil level to the first break.
A well rooted cutting with a potential for
strong, vigorous growth should be selected and potted up into a pot
size that will just accommodate the root system comfortably. A split
cane is inserted, as near to the stem as possible, care being taken
not to damage the young root system, and a tie should be made as low
as possible to the cane. Support for the young plant is essential at
this stage and any deviation from straight, upright, must be avoided
by frequent ties as growth extension of the stem proceeds. The
directional pull of light, or "phototropic" effect is very
strong and once a curvature is established correction is rarely
possible.
At this stage growth is entirely concentrated
on building a strong trunk. Leaves must be retained to assist in the
process of enlarging the diameter of the trunk. Early laterals may
also be retained but should be removed before they affect the clean
line of the trunk, for if left to develop they often produce a
pronounced lump at the nodes. Particular attention must be paid to
potting requirements. It i s very
important that no overcrowding of
roots occurs, as this will result in hard wood and an inducement to
flower. Roots should therefore be inspected frequently and, as soon as
they appear through the side of the root ball, the plant moved on to
the next size of pot. When repotting plants that are required to
produce fast. vigorous growth. they should always be potted on before
the roots emerging from the side of the root ball reach the bottom of
the pot. Failure to repot in good time will allow the roots to wind
around the ball and commence the "pot habit". If this is
allowed to proceed unchecked it will be almost impossible for the
roots to penetrate the fresh soil in any future potting.
As growth proceeds the development of the head
section must be attended to. The number of laterals required for this
is dependant to a great extent on trunk length, an important feature
of a good standard being balance, that is ,the depth of head in
relation to diameter and length of stem. This is usually considered to
be a depth of head one third of total height, with the diameter of
head in proportion to the depth. These measurements can only be an approximation
and the grower will, with experience, develop his or her own
individual style. Full weeping standards with a depth of head half the
total height of the plant look delightful but are rarely seen these
days in competition on the show bench.
Once the full height is reached,30 in clear
stem plus the section allowed for the depth of head, the top must be
taken out and, if they have not already been removed ,all the side
shoots up to the first break are removed. However the leaves must
still be retained on the trunk at this time. The resulting lateral
growth in the head section is allowed to develop and the first stop is
dependant on the type of cultivar being used. It is impossible to
state categorically that this should be done at two or three pairs of
leaves, as much will depend on the length of joint between the leaves.
One should be very conscious at this stage of the eventual diameter
and density of the head required, and should attempt to visualise the
number of stops possible to obtain the desired size and shape in the
finished product.
Stopping of laterals and side shoots continue
gradually building up the head. Regular feeding with a balanced
fertiliser is continued then when the laterals have been stopped twice
all leaves are removed from the main stem. Many growers try to select
shoots that have three leaves instead of leaves in pairs to use for
standards as the head builds up more quickly.
