Nordman
Fir ( Abies Nordmaniana)
A tree with a classic Christmas tree shape & a dark
greed glossy needle, this tree has become the most popular
of the tree varieties. It has good needle holding once
the tree has been cut and is inside the home.
From the growers point of view, it is capable of being
grown on a number of different soil conditions and land
types and , when in the most favourable soils produces
a very uniform crop of trees.
The Nordman Fir originates from the Caucus Mountains
and occurs on both sides of the mountain range. Seed
for Christmas tree production is therefore collected
in either Turkey or Georgia
There is a preference for the Georgian seed as this
is from the northern side of the mountain range and
the trees naturally inhabit an area with a colder climate
than those from the southern side. This means that they
are naturally later flushing in the spring and are much
less likely to suffer from frost damage. The area Ambourlaui
has become a favoured region for seed collection, and
this seed has become the most famous region for seed
to be used for the production of Christmas trees.
Fraser
Fir ( Abies Fraseri)
Originating from the United States, particularly in
the region Mount Rogers, this has become a popular tree
due to its similarity to the traditional Spruce tree,
but with excellent needle holding. It grows quite quickly
in comparison to other firs, but unlike its cousins
can be readily pruned to shape with very good result.
It has the advantage of a strong scent that comes into
the home.
Fraser can be very site sensitive and will not tolerate
wet conditions. Even as quite a large tree ( 1.2 –
2.0 metres) if the root structure becomes very wet,
then it can cause death quickly.
It has recently been dogged by aphid attack across the
country which has led many growers to stop production
of this tree. Whilst the problem can be treated it requires
close attention to treat it properly. Some growers have
found it impossible to eradicate.
Noble
Fir (Abies Procera)
From
the North West United States, the tree was originally
introduced here by the explorer Douglas. It is still
found growing on the mountain ranges of Washington State
& Oregon.
As its name suggests Noble can provide a find Christmas
tree. It can be very Blue in colour and provide a lovely
scent. However it has proved exceptionally difficult
to grow with many pitfalls for the grower. Consequently
it is now only produced in limited numbers and rarely
produces a uniform crop of a high standard.
Noble has proved to be very site sensitive and can also
suffer from a needle necrosis that makes the tree unsightly
due to brown stripes on the needles caused by a lack
of calcium in the tree.
Where it is good it is very good, but it has proved
difficult to justify as a commercial crop.
The foliage differs from the Nordman in being matt in
texture not glossy and veering towards a blue if not
very blue colour. Rather than flat the needles are “hockey
stick” shaped.
Norway
Spruce ( Picea Abies)
Still
regarded as the traditional tree, it has been overtaken
in popularity by the Nordman fir in recent years
It occurs naturally throughout the UK and the rest of
Northern Europe. It is because of this and its ability
to grown well on a number of sites that it has become
a popular tree.
It grows on a wide variety of soils and is easily grown
in virtually all conditions providing there is good
drainage. It is easily shaped and a grower can expect
to get a very high volume of good quality trees if he
invests time and money in a regimented pruning regime.
It has become less popular with growers in recent years
due to the low returns they have been realising and
is now produced on a small scale.
Serbain
Spruce ( Picea Omorika)
A close relative of Norway, this tree
grows naturally in colder climates than Norway. As a
result it is later flushing in habit and is often used
by Foresters in frost pockets.
Similar to Norway, it has the added attraction of a
Blue underside of the needle that from a distance gives
it a two tone green/blue look.
It is sold as an interesting alternative, and still
has a place as an alternative variety of tree.
