in the teeth of the gale

Today I got on with weeding the bed on the way in to the garden, which is what I was doing yesterday.  I've never really got the planting in this corner to work.  When I started off I planted a couple of crab apples, wanting to link the edge of the garden visually to the residual apple orchard beyond.  I still believe it can help anchor a garden in its landscape to copy or echo plants from the broader view inside the garden.  Around them I planted epimediums and Vinca minor and other shade tolerant ground cover plants, having an idea of a little woodland planting.  I had overlooked the fact that until the trees grew the bed was nothing like a woodland, but sunny, windy, and with thin, sandy soil quite unlike the leaf mould enriched earth found in woodland.  Then rabbits ate the bark of one of the trees one cold winter, and I had to start again with a new tree.

The bed is backed by a mixed field hedge, which we had planted when we moved in.  It was a condition of the sale that we would mark our boundary within three months.  The hedge is a useful hiding place for birds, and breaks the force of the wind a little, but sends questing roots out far into the bed, making the problem of the dry, thin soil even worse.  I experimented with Phormium and dahlias, thinking that it would be fun as you drove in through the entrance to be greeted by a blaze of colour, and know that you had arrived, but it was too dry for the dahlias, and the Phormium weren't a great success either.  The group of three 'Jester' functioned as snail hotels, and one of them began to revert from drooping and pink stripey to upright, more vigorous and plain green.  I've seen other pink striped Phormium do this, and am now suspicious of them as a breed, though I've never read about it as a widespread problem.  'Jester' was removed, leaving one upright form which is going to have to come out as well, since the drought, rootiness and two cold winters have destroyed whatever charms it ever possessed.

A portugese laurel, Prunus lusitanicus, that the birds brought, is doing well, as is a bird sown holly.  A fine variegated holly that I planted is handsome, but desperately slow growing.  There is a mystery berberis, which I think is the rootstock of a very early planting of B. dictophylla dating from my commuting days.  A Viburmum tinus finds it too dry.  Olearia nummulifolia grows solidly, but incredibly slowly.  The moroccan broom, Cytisus battandieri, is a triumph.  I've fiddled around with bulbs in the past.  Two cold winters put paid to a couple of pittosporums and a restio, and the meagre soil and root competition from the hedge have pretty much finished off a Cornus kousaLonicera tatarica, a shrubby honeysuckle with red flowers, no refinement but a cast iron constitution, battles along.  A colleague with a very dry garden says it does well for her.  A large Weigela florida 'Variegata' does OK, and a Philadelphus.  Due to poor record keeping I am not entirely sure which one.  One Scotch rose did well, as they are supposed to on sand, while the other died.  A yellow berried shrubby ivy was damaged by snow, but the propped up remains are sort of OK, though it isn't luxuriant, and a chunk of the ivy hedge is half dead.  The supposedly tender Ribes speciosa lives on, though on the small side, and a dwarf lilac close to the hedge does surprisingly well, as do a couple of old fashioned peonies.

In summary, it is a dog's dinner.  A mess.  A memorial to unrealistic ideas, changing plans, and general lack of coherent thought.  It is a peripheral part of the garden, in the sense that one isn't going to go and sit by it, but it is part of the garden that everybody who comes in or out sees.  What it needs is some ground covering, weed smothering, possibly evergreen planting, so that it looks like a well-furnished background to the rest of the garden and I don't spend too much time on it.  My current aim is to remove every dead shrub (I didn't mention Hebe 'Great Orme', another martyr to cold) including the roots (oh goody, more work with the pickaxe) and pick out all the weeds I can find.  Then I will apply a thick coat of mushroom compost and a topping of strulch.  Then I'll wait for the roots of grass I missed to reshoot, and zap them with glyphosate.  Next spring I'll replant.  That's the plan.

Today was extremely windy.  One reason for getting on with the entrance bed, apart from the fact that it needs doing and I hadn't touched it so far this autumn, was that I didn't fancy being under any of the trees, in case bits fell off.  It was a cold wind.  I was wearing a cotton vest.  Then two thermal vests designed to be the base layer of a multi-layered outdoor clothing system, one with a polo neck and the other inherited from the Systems Administrator when it got too small.  Then three cotton t-shirts, one with a collar.  Then the new Millets fleece, with a funnel neck.  Also a fleece neck scarf with drawstring top, and fleece hat.  On my lower half I had cotton trousers over thermal leggings.  Customers who (kindly) ask me at work if I don't get cold have no idea how many layers you can wear, and still move.  But it was very, very windy.  The whizzer stopped turning for a while in the middle of the day.  Presumably it had to be turned off, in case it whizzed too vigorously and broke itself.

I went to the dump first thing, and saw a pied wagtail.  I only ever seem to see them on roads and in car parks.  When I was a child I used to see them on the porch roof.  I am convinced they must eat asphalt.

potholes

The revival of the wind turbine was a brief affair.  It has stopped again.  There is a brisk (and chilly) wind blowing, and I should have thought the country could do with all the power it could get.  The thermometer in my car believes it is 3 degrees C.

Things around here are looking pretty bashed up by the winter.  As well as lots of flattened road signs hit by drivers in the snow, there are a phenomenal quantity of pot holes in the roads, and some burst water mains.  Water is flowing across the surface of the main road on what is already a nasty bend and dip, so that will be an accident waiting to happen the next time there's an overnight freeze.  I hit a pothole in one of the lanes taking bags of sheep's sorrel and other weeds not fit for the compost heap to the dump.  By the next day I had a flat tyre, which flattened again when reinflated, so now have a new tyre.  That's forty-six quid I would rather have spent on something more interesting.  I now crawl along the lanes with extra vigilance, eyes semi glued to the surface of the road, which is not ideal.  I'm not sure that sticking to the main roads is any better, as those have holes as well and I'll be travelling faster when I hit them.  The lanes on the farm are quite bad.  Our neighbouring farmer is very good about doing his bit, but we will have to do the final stretch to our house.  If only we didn't both have colds.

The Whizzer eventually whizzes again

The wind turbine on the farm behind the house has finally started turning again.  This was installed in the first half of last year.  The plan, according to the leaflet the farmer dropped round, was to generate green energy for the farm, and sell the surplus to the National Grid.  I wasn't thrilled at the idea of having a wind turbine in the middle of the view from the sitting room, but since I do believe that we need to work out ways of reducing our dependence on fossil fuels I didn't feel able to lodge an objection on the basis that I didn't want to look at it.  Besides, I don't mind them when I see them on holiday in the Netherlands, so I thought I'd probably get used to it.

When it was put up it was larger than I'd visualised, a quantum too large for the landscape, rising up to three times the height of the nearby trees.  A red light on top to warn low flying aircraft (or round here army helicopters) meant that there was no ignoring it even at night.  It did possess a certain fascination once it started working, the blades slooshing lazily in light airs then working up to a brisk whirl when the wind got up, the face of it turning to face the wind direction.  Ooh, I would think, the wind's gone round to the north.  I could learn to regard this as animated landscape sculpture.  We nicknamed it The Whizzer.  Then it stopped working, and men (looking very small) could be seen climbing around on the top of it with the wind turbine equivalent of the bonnet up.  Stop-start all summer, more visits from the engineers, then a while before Christmas it gave up completely.  It was stationary all through the cold spell in December (admittedly there was no wind for a lot of that) but even on breezy days nothing happened.

Someone who knows a bit about novel methods of power generation (he works in the cement plant industry and is your man if you want to know the calorific value of a cow) said that the trouble with solitary wind turbines is they produce such dirty power, the National Grid doesn't especially want it.  But yesterday a crane appeared next to the turbine and lifted off the whole top, and today it is turning again, so it looks like the bearings had gone.  Or something.  I can't think the farmer is too happy.  Even at market-distorting subsidised electricity rates designed to boost investment in green technology it can't be making a decent return on capital, and at the current rate of progress I should think it is going to take an extremely long time to ever recoup the energy costs of putting it up in the first place.  Until I can see it working better than it has so far I shall be opposing any more planning applications for farm wind turbines with extreme vigour.
