Now that so many plantations are being felled, we might
take the chance of using the slabs which are growing into mountainous heaps
about the country. If these were used as a fence allowing a space between
each slab, they would make a fine windbreak for a few years until cover
could be grown behind them.
In a section devoted to the heartbreaking job of growing
cover or shelter belts in a windswept district close to the sea, let me
voice a plea for the care of whatever patches of scrub growth we happen to
have about the township. It always surprises me how different places are in
this respect. Here in Coigach there is no growth of birches, rowans or
willows near the crofts in any of the townships, yet a few miles north of
here there is abundant birch scrub exercising a most beneficial effect on
the crofts. It is so easy to overlook the good things we have and to take
them for granted. Once natural cover has gone it is difficult to replace,
and with the best of good luck it takes several years to grow.
The formation of shelter belts round the townships will
take up some of the present common grazing, but it would be well worth it.
The acreage lost could be easily replaced in grazing value by a co-operative
slagging and liming of the common grazing outside the new belts. When the
Border sheep farms were being improved 150 years ago, it was advised that a
twentieth of the whole available grazing should be given up to shelter
belts. We should not need as much as this in the West Highlands for a
considerable acreage of the grazing is at high altitudes where trees would
not grow anyway. Personally, I think a fiftieth of the ground given up to
shelter would be enough. There would be little point here in suggesting how
deep the belts should be, for all such dimensions would need to be reckoned
individually for the places to be planted.
AN ARDGOUR CROFT
Crofters in some of the townships I know in the
Islands and on the outer coasts would think life on such a croft as this
to be a favoured one. Ploughing a good stretch of ground with two horses
(not ponies) and a full-size plough, the natural oak wood providing good
shelter, and a market for all there is to sell only nine miles away. I
have heard crofters say, "I would cut down all that wood and get more
grazing: it's poor timber anyway." Such men have not studied Highland
history and the consequences of removing the timber and scrub from too
much of the ground. Shelter is one of the amenities of life and a fair
proportion of timber means conservation of soil and of beneficial wild
Probably the best tree we have for shelter planting near
the sea is the sitka spruce. It is no good using Norway spruce or Scots pine
because these species scorch badly with spray. Sitkas do well, and it seems
to me now that there is little point in having three rows of mountain pines
on the seaward side because, good as they are at the spray line, sitkas are
equally good. Mountain pines are poor trees and do not live long.
Normally, you do not plant as close as 2 feet apart. Such
closeness would make a forester's hair stand on end, but I believe that is
what we must do when we are planting in the teeth of gales from the
Atlantic. Thinning can be done later, but your shelter must have shelter in
its early stages. The trees to be planted should be young, say
two-year-olds, and short stocky ones at that.
If the stand of sitkas gets going it will be almost
impenetrable at ten or fifteen years old, and of course, there should be no
trimming of the stems to get clean sticks of timber as one would in forestry
practice. It might even be good to cut the crowns off when the trees reach
20 feet in height, for sitkas stand a lot of rough treatment.
In situations where plantations could get started rather
easier, a shelter belt could consist of a greater variety of coniferous
trees, with room left among them for elders and cotoneasters which would
provide bottom growth. However, keep clear of Douglas fir in a very windy
situation; and larch also if there is danger of spray. A shelter belt with a
scrubby bottom growth would hold a lot of summer migrant birds which are a
help to agriculture.
When it comes to growing cover for the west coast of the
Outer Hebrides, I admit myself beaten at present. We should have to start
with a toe of growth such as whin, and build up slightly taller things
behind that. It is indeed a field for research and experiment. Nevertheless,
when one sees some of the trees, hedges of Escallonia and banks of
rhododendrons which occur in some places in the west of Lewis, there is no
reason for despair.
43. Growing Shelter for a Garden
Some day, I hope the problem of growing a shelter hedge
for a garden on the Atlantic seaboard will be tackled on a demonstration
croft run by some institution or the Department of Agriculture, for making
mistakes is an expensive hobby for the individual crofter. I am quite sure
many mistakes will be made before we have reduced the problem to merely
fulfilling a given procedure. As far as I can see, we have no native shrub
that can endure the worst the Atlantic can do and grow to a reasonable
height within a few years. Also, I am quite sure we have not scoured the
world carefully enough to collect all the wind resisters which there must
Here on Tanera our garden is set at the eastern end of a
funnel-like glen and the wind seems to be magnified. I intended to have a
hedge of Cupressus macrocarpa which, I am told, does well near the
sea, but I was advised to use Lawson's cypress instead, as C. macrocarpa
was apt to die back. Well, I lost the lot in the first winter through
the action of a spray-laden east wind, and I am now told that C.
macrocarpa does not die back as long as you do not cut the top off when
it reaches the required height of the hedge. Anyway, my next try was with
hawthorn, and after three years this hedge is certainly growing, but does
not yet provide any shelter. I put some little beeches in with the thorns
but nearly all have died. Both beech and hawthorn require lime, and I
trenched the whole length of my hedge with mortar rubble before planting it.
The thorn hedge would be very unlikely to grow on a peaty soil.
There is another shrub called Escallonia which
makes good hedges in the south-west of Ireland, and it grows on our west
coast too, but my experience has been that it could not withstand March
gales from the east in a really open situation. In any case, the young
plants are expensive.
My greatest hope at present is the large oval-leaved,
blue-flowered Veronica which grows in many gardens on the West
Highland coast as far north as Lochinver. It is a wonderful shrub
originating in New Zealand or Chile, I am not quite sure which, because I
think this West Coast Veronica is a hybrid. It is bright green in
colour all the year round and has smooth fleshy leaves. The flowers seem to
appear at all times, for my own shrubs are hardly ever without blossom. The
shrub grows very close and forms a mass like a half sphere of foliage after
two or three years, when it is 2 feet to 2 feet 6 inches in height. Another
good thing about it is the ease with which cuttings can be struck. We keep
one bush as a kind of stock bush from which we have taken dozens of slips.
These we stick into the ground in autumn, and by spring they are neat little
three-sprigged plants suitable for planting out as a hedge. I reckon that a
really good hedge can be grown in five years in some of our windiest
situations. I have still to determine its range of soil between the two
extremes of peat and shell-sand.
When planting a hedge, prepare the land well beforehand.
Trench it 3 feet wide in autumn, leave it all winter and plant out your
young hedge in late April, thereafter watching that the plants get water
during the dry weather of May and June. Seaweed would be an excellent mulch.
If you can bank up a turf or two along the windward side, such shelter would
help the young plants in their first year. As the hedge grows it should be
pruned back to keep it growing thick. Thorns should be planted 6 inches
apart but Veronica can be a foot apart, and even at that distance
alternate bushes could be removed after two or three years and used
elsewhere. Plant close, however, at first, for the shrubs shelter each
44. Further Thoughts on Shelter
When these sections on growing shelter were appearing as
weekly articles I had many letters on the subject, several asking for
further information and others giving me valuable knowledge based on
experience. It seemed to me the right course was to pass on this knowledge,
for I could have no doubt of the wide interest among crofters in growing
shelter for a garden. And from this very fact I would go the further logical
step and say that if crofters show interest in growing shelter for a garden
they must have a desire to make a garden, and a garden is by definition a
place where you grow things, food plants and flowers; it is not made to
provide a playground for hens—even if these troublesome creatures think so.
Some of these letters asking for further advice on hedges
finished with the entirely practical question, "Where can I get the
necessary plants?" Quite candidly, this was a bit of a poser and emphasized
the lack of attention which has been given to the subject by educational and
official institutions. Several parts of the West Highland coast are
admirable for growing shrubs quickly, yet how many nurseries are there over
here which could set about supplying a demand for shelter species? It is no
good being offered specimen bushes of Escallonia or Veronica
at half a crown or four shillings each; we want quantities of young stuff,
newly rooted cuttings and the like, at a pound or thirty shillings a
hundred. I nearly suggested" in the section on shelter
for a garden that some business-minded crofter with the
right sort of place would do well to start a nursery of Veronica
bushes. Well, I say it in all seriousness now, and if those lairds with
plenty of well-grown hedges or bushes of Escallonia and Veronica
about their policies would be so kind as to take some hundreds or
thousands of cuttings and strike them in some corner of their ground, they
would be doing their fellow-men a good turn and within a year or two make a
The cypress originating from a windswept spray-ridden
peninsula in California, known here as Cupressus macrocarpa, is a
very popular hedging plant which I mentioned in my earlier remarks on
shelter. I remarked on its tendency to suddenly die back, especially if
topped too soon. A reader in Argyll who is a keen amateur forester, wrote to
say that this was not his experience, but that the trees do tend to die
eighteen to twenty years after planting if they have been placed too close
to each other. The individual trees must have room enough to develop a
crown. He suggested planting 3 feet apart, the trees being one-year-old or
one-year transplants. C. macrocarpa is a difficult transplanter and
very susceptible to drought when first planted, says my correspondent, so if
possible the young plants should be transferred from pots to avoid root
exposure. Many of the queries I have received have been from the Outer
Isles, and as all plants of this species if used would have to be imported
from the mainland, it would be advisable to take heed of my correspondent's
expert knowledge and buy only C. macrocarpa in pots. The young plants
will be expensive, but at least there will be some expectation of success.
Once again, let me emphasise the necessity of preparing the ground first
where the hedge is to be—digging it deeply first, but my correspondent says
manure should not be dug in for any of the coniferous trees, of which C.
macrocarpa is one. When the plants are in, the surface of the ground may
be mulched with seaweed to conserve the moisture.
My correspondent further said that after the first-year's
growth of the C. macrocarpa hedge, a level top should be aimed at by
nipping off the leaders which grow above the average height. The right shape
of a hedge is one thick at the base and coming more or less to a point at
the top. This shape of a hedge sheds the rain, does not get broken down by
snow, and allows a maximum of light to reach the lower growth.
The same correspondent held out little hope of the
so-called Antarctic beech being any good, an opinion confirmed by another
writer who knew the plant in the Falkland Islands. I understand the plants
are expensive, difficult to obtain and liable to succumb to the variability
of our climate. Cold may not kill a plant, but sudden alternations of
mildness and cold will.
It seems perhaps that I did less than justice to
Escallonia macrantha as a hedging plant for the Islands. Certainly it
does well where exposed to winds from western airts, but from my own
experience and from what I learn from one or two other letters, a gale of
east wind can make it look sick. This shrub grows splendidly from cuttings.
Another correspondent asked me not to forget the humble
willow, and mentions the practice in Strathclyde of planting the
quick-growing withy as a hedge and plaiting the stems as they grow, to form
a sort of living wattle hurdle. This should help to provide the first cover
for a garden. Another plant suitable for exposed situations is the familiar
whin or gorse bush. This does not transplant easily, so should be sown where
it is wished to have the hedge, and in its young stages protected from
stock, which are very fond of the new tender shoots. Nip back the first
leaders to make the plants sprout into a thick, compact, bushy hedge. In
very exposed positions it is a good plan to sow the seed in a shallow trench
so that the young plants get some protection, as is done in the windswept
I forgot to mention earlier the hardy and thorny
qualities of the Worcesterberry, a plant which is a cross between a
gooseberry and black currant. It grows quickly, its thorns will pierce the
hide of the most inquisitive gate-crashing cow, and it produces a good
fruit. To use the words Neil Munro put in the mouth of the fox who ate the
bagpipes, "There's both meat and music in it."
There is also the myroballum plum, a sort of thorny wild
plum which grows very close and becomes impenetrable. Nurserymen usually
have a supply of young plants for hedging. The ground should be dug well
first and lime worked in.
