Propagation, Spacing and Planting
Propagation
The Willow Sets (unrooted
standards) are normally grown from stools (Tods) which
are planted in the
ground, these
are allowed to grow and are cropped every fourth
year. Ground preparations, fencing and subsequent
weeding and
grass cutting or spraying are essential to prevent
the young shoots being over run with undergrowth
for the
first year of each four year cycle.
Selection of Sets during this period is not advised,
competition for light encourages the Set to grow
straight and tall. Once cut the Set is graded and
where possible
a four length Set is obtained. Shorter Sets are
normally included where a strategic leader is evident,
thus
allowing further pruning once the Set becomes established.
Spacing and Ground Preparation
Normally a site visit is advisable
to ascertain the suitability of the area, the most common
being river and brook
water courses and low laying, often disused water meadows.
Soil types have a varied effect on the growth and quality
of the trees, for example, good quality soil over clay
and well drained with a high water table of say 18" to
30" is ideal.
Heavy peat is less suitable and
to some extent sandy soil having the effect of 'speck'
marks on the finished products. Trees planted in
plantation form will benefit from light soil cultivation
if practical
and to a lesser extent keeping the undergrowth down
will prevent heating and subsequent secondary shooting
from the base of the tree. Ground maintenance in
single rows along rivers is not normally practical.
Planting
Sets are planted December to February
with a crowbar or similar. A point or 45 degree angle
may be put on the Set and a little water poured into
the hole prior to pushing it right to the bottom of the
hole. It is essential that the Set is in the upright
position, no staking is required and a rabbit guard must
be fitted. 'Firming up' should take place in March, taking
care not to break the newly formed roots.
Maintenance
Maintenance is of paramount importance,
trees neglected for one year only during their lifetime
have little or no commercial value. The side shoots can
be rubbed off in the early stages, or if allowed to grow
beyond this stage cut off flush with the bark in an upwards
direction, never pulled off, especially in the downward
direction. They should not be allowed to become 'woody'.
The first five years are the most difficult to carry
out maintenance, after which the bark will harden up
and the side shoots become less evident. Fencing against
livestock is essential, horses and cattle in particular.
Sheep may graze, but only when the trees are at least
half grown.
