Willow
Cuttings
Willow readily grows from willow cuttings making propagation
easy
You too can grow your own willow for weaving or perhaps in the
garden to enjoy the early spring catkins and winter colours that
are typical of willow species. JPR Environmental has over
20 varieties of willow growing at our coppice in Gloucestershire.
You can see a list of the varieties available and a brief description
of their attributes by looking at our willow varieties page.
Live willow cuttings are available from November to March. They
are 25-30 cm long and vary in thickness depending on the variety
chosen.
Order now for delivery between November and March.
Success at growing willows from cuttings depends upon good site
preparation, correct spacing, careful planting and a long term plan
for dealing with weeds.
Site Preparation
The amount of preparation required on a site identified for planting
depends very much on the scale of planting being undertaken. Whatever
the scale, good weed control in the first 2 or 3 years is very important
to allow cuttings to establish effectively.
With large scale planting the usual practice is to spray the site
in the late summer with a broad-spectrum contact herbicide, plough
to 300mm/12 inches depth and power harrow in the spring. This provides
a good weed free tilth that makes future weed control measures more
straightforward.
If planting on a smaller scale cultivate the soil to a depth of
300mm/12 inches to produce a fine tilth. An alternative to using
sprays for smaller areas is to use either a plastic sheet or a water
permeable woven polythene sheet. The cuttings are planted through
the sheet which increases soil temperature in the spring and retains
water during the summer months. The thinnest sheets will only last
a year but in our opinion using a sheet that will last at least
3 years is well worth the investment in the long run.
Planting
The ideal time for planting is from mid January to the end of
March. Planting in the autumn risks the cuttings rotting off and
planting later in the spring risks damaging the root nodules that
will have started to sprout. The cuttings supplied will be between
250-300mm in length. Cuttings should be planted as soon as possible
after receipt. If this is not possible they should be stored in
a fridge until planting can be undertaken, though remember the sooner
the better. Cuttings are pushed vertically into the soil leaving
about 20mm proud of the surface. If the soil is such that you are
having to force the cutting in then make a hole in the soil with
a metal rod, basically you are trying not to damage the bark of
the cutting when planting. Firm up the soil around the cutting.
Make sure that the cutting is the right way up, buds pointing upwards
- they will grow upside down if they have to but they prefer not!
Optimum spacing arrangements for growing large numbers
of willows depend on which varieties are being grown, what size
rods are wanted, what the weed control methods will be and how the
willows will be harvested - no wonder everyone will give you a different
opinion! The closest we have heard is 25cm x 25cm and the furthest
apart (for biomass production) 1.5m x 1.5m - not counting cricket
bat willows which are spaced 25m apart! Generally the taller and
thicker the rods required the further apart they should be spaced.
A common spacing is around 30cm x 50cm for fine basketry willows
and 40cm x 80cm if tall osier is required for hurdle/sculptural
work.
Long term weed control
Weeds in this case are defined as plants
which cause either a reduction in the number of shoots from each
stool or a reduction in the size of the rods. Plants, such as nettles,
that have a rapid spring growth will cause a reduction in the number
of shoots that will survive as the willow struggles to reach the
light. Other plants which cause problems in a willow bed include
bramble, docks, couch grass and the dreaded bindweed.
Though, this said, it may be that having a low growing ground
flora is actually beneficial to the success of the willow because
it provides a habitat for insects that feed on aphids and other
willow pests.
There are three principal weed control alternatives:
Spraying with a foliar acting herbicide when the stools are dormant,
usually restricted to large scale growers. The most appropriate
herbicides are only available to licence holders and need specialist
equipment to ensure the correct dosage.
Hand weeding with hoes and hand hooks. This has the advantage
of being able to target undesirable species though on large plantings
can be somewhat daunting. Regular and often should be the mantra
to those using this method - this will save time in the long run.
Mulching. This can be done with ground sheets (best done before
planting), straw, cardboard or other organic material. It is important
not to smother the growing shoots which can happen if the wind blows
the material around. Remember that adding too much organic matter
may cause more problems later with nettles etc. that invade the
rich soil.
