These
are our basic guidelines on the planting and immediate
after-care of new trees and shrubs.
Timing
Container-grown plants can
be planted at any time but must be kept well watered.
Late September to the end of April is ideal. Bare
root plants should be planted between November
and March.
Care of Plants Before
Planting
Keep the soil moist within
the pot of a container-grown plant prior to planting.
If you intend to store bare-rooted plants, it
is a good idea to dig them into a vegetable garden
or similar as a temporary measure, making sure
that all roots are covered with friable moist
soil.
If
you are planting one of Nicholsons’ own
bare-rooted plants, you should note that these
are supplied in special co-extruded bags. These
plants should be kept securely tied in their bags
until they are ready to be planted. Plants in
their bags should be stored away from direct sunlight,
frost and wind, and the roots should not be allowed
to dry out. Ideally, dip the roots before planting,
and carry out planting within a few days of purchase
or seek further advice.
The
Hole
Dig the hole as large as
possible, ensuring that the roots or root ball
of the plant will fit well into the hole. Typically,
the hole will need to be one-and-a-half times
the size of the roots or root ball, both wide
and deep. It is important to dig over the bottom
of the hole as this will aid drainage and assist
good root establishment. Beware of clay sites
and of creating a mini pond – ensure good
drainage.
The Soil
Prepare your soil well.
Cultivate to a fine tilth (maximum clod size should
be less than 40mm). Check for compaction at the
base of
the hole, ensuring you can dig freely to 450mm.
If there is compaction, loosen the soil.
If
you are unsure about the suitability of your soil
type to the species you are hoping to plant, please
don’t hesitate to contact us. A good planting
compost should be dug in to the base of the hole,
as this will encourage deep root growth. A suitable
stake (where appropriate) should be driven well
into the hole prior to back filling.

Fertiliser
Depending upon the plant
species and the condition of your soil, you may
wish to consider mixing in very well rotted manure
(approximately 20% of the soil volume) to improve
structure and fertility. Alternatively use a fertiliser
like Growmore in the summer or a slow release
fertiliser such as Osmacote in the winter.
Planting
Position the tree and adjust
its depth in the hole.The final depth of the tree
must be at the same depth as it was in the container
or just
above the start of the stem base. Back filling
should be done with a mixture of soil taken from
the hole and some planting medium. If a
watering tube is being fitted, it should be included
as the plant is placed within the hole (see
diagram above).
The
soil should be added steadily in 50mm layers and
lightly with your foot. Take care not to squash
the soil as this will force out air and create
anaerobic conditions.
- Smaller
Bare Root Trees and Hedging –
similar practice applies, but the hole can be
smaller and in some cases notch planted without
the need for extra compost.The need for weed
control is vital as mulches are often not economic
to apply on a large scale.
-
Rootballed Trees – special
care should be taken when planting rootballed
trees.The rootball is often wrapped in hessian
and wire.As little disturbance as possible to
the rootball is vital – once the plant
is in the ground the wire should be undone from
the root collar and folded back. The Hessian
should also be pulled back. Both wire and hessian
will rot in time and do not cause any problem
to the growth of the tree. If in doubt ask for
further advice.
Staking
Trees may need staking and
this will depend on the site conditions and the
size of the tree to be planted. Smaller trees
and trees in sheltered sites may not need staking
at all.
With
some container grown or rootballed trees, it may
be difficult to position the stake close to the
main trunk so two stakes should be used with a
cross rail and the tree attached with a tree tie.
Stakes are only a short-term measure and should
be removed by the third season.This will allow
the roots to anchor and support the tree naturally.
Do not worry if it bends in the wind – but
check for excessive wind-rock and re-stake if
concerned.

Guards
Smaller trees especially
may need protection and we have listed various
options in our Sundries
section. The guards should be appropriate to the
size of the plant and the type of pest. They should
be fitted at the time of planting.
Mulching
To complete the planting
a mulch should be spread 75mm deep around the
base of the tree to retain the moisture after
planting and
suppress weeds. Allow a 50mm gap between the trunk
and the mulch.
Top
Dressing
Top dress the tree with
Fish, Blood and Bone in March at the rate of 3oz
per square yard and mulch annually to ensure maximum
growth
and quick establishment.
Watering
Water in well, but do not
saturate. Water is the most essential factor for
any tree in its first season. Please see our Watering
Guide for more information. Use the squeeze
test and check regularly depending on the weather
and size of the plant.
Aftercare
Weed control is vital to
the successful establishment of the plants. Although
mulch reduces weeds, other forms of weed control
may be needed. See our Weeding
Guidelines for further details. Spirals used
for rabbit control can often be taken off after
4-6 years.Take them off piecemeal and check for
new damage before removing them from all your
trees. Check them regularly as they can occasionally
strangle the tree.
Larger
trees that have been staked and tied will need
regular checks to loosen the tie and after 3-4
years may need the stakes removing
altogether. The tree should not rely on the stake
for support for too long – they need to
be allowed to move to encourage the stem to
strengthen and take the full strain of the wind
itself!
Irrigation
Where planting is carried
out in large schemes, it is possible to install
an irrigation scheme with individual drippers
to trees and trickle pipe on hedges and borders.
See Watering Guidelines
for more details.
