Winter

It sleeted the other day in Teddington, which I'm taking as a sign that the Wintersmith has stepped up for his turn at the dance.  As there's no planting or plant-activity left to do in the garden, I thought it might be an idea to just take stock of where me and my garden are at this year and what's planned for the quiet season.

First, we have a new addition to the family.  Our Sam had a baby.  I've mentioned her before, her name is Ellie, she's turning 1 in December and she's already toddling at a run.  She's got a fair vocabulary up to now:

Miaow = Bill or any cat
Doos = Juice
Doyan = Diane
Durj = George
Door = Door
Edjig = Hedgehog
Mum = Mum
Nana = Nana
Chickenchickenchicken = Chicken.

I buried my Dad this Autumn, which was as hard as you might expect.  I might write more on that in the next few months, but I'm in a weird sixth stage of grief right now.  I've gone through the five as normal, but my mind still isn't at rest so I've been making a lot of jam and I've been poopsocking heavily on the xbox.  On the plus, I can now make lemon curd.  He liked lemon curd did our Cubby, he liked the Beatles too, so when I did a job up Hampstead the other week I swung by Abbey Road on the way home, spent some time sitting by the zebra crossing with my thoughts.

It seems I've been shortlisted for a job as a lab tech.  Won't find out until tomorrow.

The garden then.  The trees out front had a fungal thing but I've treated that organically by dousing the leaves with diluted milk and by adding calcium to the soil.  The new thornless brambles are making it easier to gather the fruit, and Ellie loves doing that.  She sits on my Mum's lap out on the ramp and picks the blackberries that grow along the handrails.  There'll be more planted on the other side too, but not just yet.  I want to get two more cherries in first.

The back garden is having its annual lawn die-off.  The back garden faces North so we can only keep a lawn for a Summer.  The fruit bed is doing well though.  The loganberry plant is halfway along the trellis now, chasing the last of the Sun.  The gooseberries are looking iffy, in that I can't quite tell if they're dead or just hibernating and I shan't know until Spring.

Out front the neighbours' fence is still a bit dodgy.  It was put up by cowboys and so in the first breath of wind it collapsed and damaged their car and my pear tree.  I've made some repairs to it (because it's cheaper than cleaning up after cowboys - the last time they came out to make repairs they dug a hole round the post, filled it with dry cement powder and buried it) but I'm still not happy, so when I get some dough I'll buy a couple 8' tree stakes and drive them 4' deep.  Against that fence I've got an elderberry and three kinds of raspberries.

I'm looking at ways to make my front garden more wildlife friendly.  The bark on the ground is attracting woodlice, I've got a log with holes drilled into it which attracts ladybirds in the warmer seasons.  Plenty of dead wood for beetles.  Once my dwarf orchard grows to size it'll start attracting bats, at which point I'll consider bat boxes in the eaves.

Now birds and hedgehogs...  My front garden has two plantable areas, which I term the Island and the Outside.  Here's a map, not to scale:

The North edge of the Island is already lined with rosemary and lavender.  I think I might continue those around the Western edge and then along the South edge.  I'll site a hedgehog box in the centre and fill out the middle of the Island with gooseberries and bush roses.  There's already jasmine and brambles growing against the railings, and together it should make for a dense enough hedge to support birds and hedgehogs.  

At the Northernmost end of the Outside, up against the wall I've got climbing roses, Etoile de Hollande, but as they grow the bottom will need cover to look nice.  I'm thinking Buxus sempervirens, maybe bush roses, maybe lavender.  This'll come out by a foot or so and again I can work in a hedgehog box.  I'll put blackcurrants in front of that.  Maybe I'll separate the blackcurrants from the rest of the bush with a little hidden chickenwire so that Ellie isn't grabbing rose prickles. 

I'll put a narrow path down the middle of the Western bit of the Outside, from the blackcurrants down to just East of the Westernmost cherry.  At the end of this path I'll put a wee storage thing in the shade of the front fence (where little else grows), while either side of that path I'll sow herbs and strawberries.  I'll also put in bee pots to encourage bees.  

Next year I'll fit windowboxes for basil and sage.  I'm gradually accumulating nice pots, some of which will house a mix of flowers and herbs, others will hold mint by itself because mint is the Britain of plants: it'll colonise the entire pot! 

This year we were sufficient in three things: rosemary, bay leaves, and blackberries.  Next year we ought to be sufficient in those plus sage, raspberries, verbena, loganberries, blueberries, gooseberries and hopefully thyme.  Thyme's tricky though in my garden.  Within the next three years we should become sufficient in those plus strawberries, basil, mint, blackcurrants, elderflower, elderberry, figs, and seasonal stonefruits (apples, pears, cherries).  

And that's been my year!

Bulbs

I've been putting bulbs in for the new year.  

Behind the pear tree I've put in crocus bulbs.  They'll come up in Spring and hopefully they'll set seed.  I'd love for some pretty flowers to become naturalised in the garden.  I'll be planting bluebell bulbs in the January to the same purpose.  In both cases, crocus and bluebell, they'll grow in the wee nooks between other plants without bothering anything.  

They go up as far as the end of the fence, the full width.  Against the wall there in back I intend to grow climbing roses up and along the wall.  I'm considering growing Elder against the fence, so it's likely that not all of my crocuses will grow to flower, but with 75 bulbs in the ground you can be sure that a few will.  

In the island I've sown French garlic cloves.  Garlic is a magic thing: break a bulb down into cloves, sow the cloves 4" apart, and each clove becomes a whole bulb!  With anything from eight to sixteen cloves in a bulb, varying by cultivar, you have a greater than exponential increase if you replant every clove.  I shan't though.  I'm going to select for my five or six biggest bulbs each year and the rest will go to the kitchen, either for braiding and drying or for pickling.  They need a nice sharp frost in the Winter in order to divide out into bulbs, otherwise you just get a slightly larger clove than the one you buried, so with that in mind I'll be hoping for a good chill in the Winter.  Apples are a bit like that too, they need a cold Winter to produce a good yield.  

The garlic's in under the bark, to the left of the rosemary and this side of the sage.  The bark's a little thick just now, but that'll rot down over the Winter and put some carbon in the soil, mitigating the worst of any frost.  I'm quite tempted to close off this end of the island with a fan-trained damson, as the extra fruit will be very welcome.  

Still waiting on my qualification and transcript.  I've earned a distinction at HNC, which is all very wonderful, but it's doing me no good if I don't have the paperwork to show to universities or potential employers.  I'm feeling rather stuck right now and I don't like it, but with luck I'll have it all sorted ready to apply for the January intake.

Preparing for college

  So I think tomorrow I'll be ordering a lot of textbooks. For £9 all-in I'm getting Principles of Genetics, Functional Histology, and Principles of Anatomy and Physiology. I'd best clear off a shelf in my room for all this (or build another shelf if I can't clear one), and fetch my Gray's Anatomy and Striker's Biochemistry down from the loft, though I prefer Lehninger's Biochemistry and will be getting a copy at my earliest convenience.  

  Getting Bioscience Laboratory Techniques next week, along with as many box files and as much lined paper as I can scrape together.  A friend has offered to lend me her copy of Essential Cell Biology.  

  The advance legwork I need to put in ahead of my practicals is well in hand.  So much so that Julia now has an entire folder of emails titled "Jo's crabs".  Yep, I'm looking at mitten crabs.  I'm also intending to look at bees and holly.  Two subjects of great environmental significance and one subject of personal curiosity.  If I get the green light for the holly study then I may find myself doing carpentry in the lab: the study will need a rig that I don't think we have, but that I can build for next to nowt.  

In 69 days' time I will be a biologist-in-training!

Borders and builds

Good news first: I got an interview to study Biology!

The back border is in place.


I've included a slab there so that Bill and George can still access the social hole without trampling the bed.  Hopefully they catch on.  On the right we have Heathers behind, Coleus in front:

And on the left we have another Heather/Coleus pairing, followed by Borage, Bergamot, Tarragon and two varieties of Rosemary.  I've left gaps of a foot each side of each fencepost; these gaps will be filled by Jasmines and later trellis.  


I've put a few planks on the shed walls and put nails in.  Saying I built racks is giving it a lot more than it is, but they do the job.  


I'm also halfway through building a long box with a lid, akin to a footlocker.  It'll sit along the back of the shed and house things like paints, fertilisers, my sledgehammer and other dangerous items; hence the timber being two inches thick.  It'll also double as a seat, though I'll be sure to mark it boldly with "NO DRINKS, NO LIQUIDS".  You could mix up half the shit in a gardener's shed and make dynamite, and I like having windows.  

It's purple for the pretty.  Meanwhile, the grass is getting unruly.  Dammit, I want a strimmer!

Grass, tools and evolution

I planted the lawn today.

  George now has no back garden for at least a week, maybe a fortnight.  I used aerator shoes to drive the seed in deep, like two inches deep.  Some's only an inch deep, having been raked in.  Some's at the surface, squashed in with my boots.  With any luck, a storm coming out of nowhere won't be as devastating a thing this year as it was last year.  We may end up with a half-decent lawn this Summer!  

  As thanks for putting the lawn in, I got given a lovely new edger.  I've never owned an edger before.  This one's a thing of beauty: dark hardwood handle, sturdy, quality lathework, and with a bright stainless steel blade.  I think I'm in love.  Can't wait to put in a proper border with it.  

Lastly then, the strawberries I planted last year are greening up and back on the grow.  More specifically: half of them are.  The other half are either dead or dormant.  Thankfully the surviving half are from all four cultivars planted.  This is a good thing because the weird second Winter we just had is not great for plants.  The limey London soil is definitely not great for fruiting plants (my strawbs are in compost, but there's soil beneath and the alkali is capable of creeping up).  

Those which survived are hardier to frost and more tolerant of the edaphic conditions than those which died.  

This is the basis of evolution.  Evolution depends upon life in the midst of death.  Those which survive go on to pass on those very genes which helped them survive.  This adapts the species to the prevailing conditions.  The surviving strawberries will propagate new plants - both vegetatively and sexually - until the Strawbrary is full.  Those new plants will be adapted to fit the prevailing conditions of my garden.  After a few more generations they'll have thoroughly evolved to fit the niche of "strawberry plant in Joey's Strawbrary", after which they'll need to evolve again before they'll be able to thrive half as well in any garden but mine.

Life plods on, as ever it has.

Good times!

So Julia took me to Kew Gardens today.  I can tell you now, as a gardener and a scientist, to be taken around Kew by someone far more experienced both as a gardener and as a scientist is a hell of a thing!  I probably picked up as much in an afternoon as I might in a month of books!  I'm tremendously grateful for the experience, and if someone ever offers you a similar afternoon I suggest you take them up on it.

I has a happy :)

The smelliest job so far!

Last night I moved the composter from the dark side of the patio to its final home by the strawbrary.

Fiddliest and smelliest job I've ever had to do in that garden, and I've done poop patrol!  

  The baseplate for the composter arrived, finally, after one lost delivery and one delivered broken.  I could not get that thing to fit on.  Nope.  No fitting on for that baseplate.  I chalked it up to the fact that it was cold outside, the composter body was at 0ºC while the baseplate was at room temperature, and so Physics has a thing to say.  In reality, this was my excuse for saying "sod it, it's 0º out here and this smelly thing is making my hands wet in 0º!"  I ended up laying the baseplate on the ground and standing the composter over it.  The weight of proto-compost should hold it all together.  

  Sliding the body of the composter up over the contents was a bit tense - would it stay together like a putrid blancmange or would it go everywhere?  It stayed!  The rest was work for a fork, a shovel, and eventually a hose.  The contents were somewhere below half the height, but as the thing is slightly conical I reckon it's full to about half the volume, or 165 litres.  Whilst I was forking out compost I took the opportunity to study the strata within.  Some bits seem to decompose faster than others.  Things that are watery (like cucumber) or mushy (like banana) seem to go first.  Things with a hard shell (like the pumpkin from Halloween) appear to take a lot longer.  Eggshells break down surprisingly readily.  Any leaves that get in there seem to turn slimy.  

  I've taken a photo of some of the strata, laid out on one of my favourite childhood building materials: the knackered, rusty sheet of wriggly tin (of dubious acquisition).  For the sake of your breakfast I've left out the bits where putrefying is actively taking place.  Upper layers on the left, lower layers in the right.  Rightmost is damn near compost!

This time next year, Rodney, we'll have compost.

Primary Succession

This is cool.

Norderoogsand has sprung up from beneath the sea like a kraken of sand.  It has since become home to 50 plant species and a bunch of sea birds.

Photo: Telegraph
  Dunes rise above sea level all the time and usually sink just as readily, but this one is different.  What makes it different is the same force which has driven our evolution from bacteria to human beings: luck.  Call it chance, fate, divine intervention, whatever.  The right factors were in place at the right time.  Those factors were a mild sea and the presence of spores from simple plants.  The mild seas didn't destroy the proto-island, whilst the spores grew into simple mosses and lichens.  Those mosses and lichens put down roots and bound the sand into a basic soil.

  Once a moss organism dies it decomposes into compost, adding organic matter to the sandy soil.  This organic matter - or humus - contains carbon, nitrogen, and other essential elements.  Birds drop guano containing further essential elements and ions such as calcium, potassium, sulphates and phosphates.

  Over time, the soil becomes rich enough to support more complex plants.  The seeds for such plants are also carried over in the stomachs of birds.  These plants have deeper and stronger root systems which will help bind the deeper layers of the soil.  When they die, their roots will decompose and leave humus in the deeper layers.  Eventually this process will clear the way for shrubs to take hold.

  There is a selective pressure here.  A selective pressure is a natural force which says "A can live here but B cannot".  In this case it is the salt water.  Sand doesn't hold rainwater very well by itself, so for now all the moisture is seawater.  Only those plant which thrive on beaches or in areas with high salinity will be able to live on Norderoogsand in the early stages.  Once the soil is rich enough in deep humus to support shrubs it should also be absorbent enough to retain rainwater.  Even so, it will still be quite saline.  Coastal shrubs will be best adapted to these conditions.

  The potential for trees to grow on Norderoogsand is uncertain.  Soil that sandy might not hold a tree firmly enough.  Deposits of lime from bird droppings will gradually improve the soil structure.  Clay would make a nice addition, but it will not arrive there by itself.  If sufficient generations of plants live, reproduce, die and decompose that peat has a chance to form then that is perhaps the best chance we have of seeing trees arrive on Norderoogsand.

  Higher land animals are highly unlikely until the ground is very very stable and the plantlife is sufficiently fecund.  Likely it'll just be birds and amphibians until the trees appear.

  Alternately, the island could be helped along.  A little clay, a little peat, a couple bay trees and this island would be halfway toward a climax community.  This won't happen though.  Biologists and geologists will argue - and rightly so - that Norderoogsand should be left alone to be observed.  Primary succession is a rare occurrence, so the data which can be gained by watching it happen from scratch is scientifically invaluable.  It can tell us something about our world that we do not yet know.  The process of succession is slow, but when seen from end to end is a miracle of nature.  I urge you to keep an eye on it.

I wish I was there...

My Botanical Adventure

Went to Kew Gardens for the first time today.  I really should've gone sooner.  The guide thingy suggests you leave yourself two to three hours to get around the place - aye, sure, if you're an anorexic on a souped-up granny scooter being piloted by the Stig!  I was there for five hours and I reckon I'm lucky if I got to experience half of it.  I'm going to include the bulk of the photos on a separate page because I took 103, but I'll post a choice few here.  I went in the Winter, so I presume you've got to see it again in the Spring, Summer and Autumn to really get a sense of the lifecycles of the specimens there.

 Me amidst an amazing collection of palms and ferns

The Coffin Tree can grow to be among the tallest trees in the world!

This fish was watching me.  

This Cycad is older than Kew Gardens.  Cycads as a bunch are older than the dinosaurs!

And for reference, here's a cycad being munched on by a Triceratops

This is a Banksia, named for a local boy...

There's a gallery of botanical art there, it has its own building, The Marianne North Gallery.  It features a load of paintings by Marianne North plus the Shirley Sherwood Collection, a collection of paintings by various artists.  There's a whole section on fungus for any myco geeks.  Sadly, no photos allowed.

I stopped for a burger halfway through.  It was a hell of a burger!  Venison.  You heard me; a venison burger!  Venison, in a burger.  I'll stop now.  

There were piranhas

The turtles were nothing like the ones you see on the telly though.  They weren't even armed!  Bit naff really.  

Now the Kew Pagoda is a bit of a local landmark.  You can see it from over the Thames in Brentford, from half of Richmond and Sheen, and of course from the top of a 65 bus.  So I decided to see where in the Gardens I could grab the best long shot of the Pagoda.  

Here's it up close

The Treetop Walkway is the highest publicly-climbable structure in the Gardens.  The Pagoda is taller but you aren't allowed up it.  Here's the walkway:

I expected the views from there to be amazing, and they are!  You need to get that high and see Brentford, see Sheen, to remind yourself that you're still in London.  


But the view of the Pagoda was obscured by tree branches.  

Still, at least in the Winter you can see it at all.  In the Summer that'll be a wall of green.  The view from the top of the Temperate Greenhouse (the biggest greenhouse) is significantly clearer, albeit with a big tree blocking part of it

Best view however was straight down the Cedar Vista from the corner of that wee lake in the North of the Gardens:


These parakeets live all over Richmond Borough.  A shitload escaped from some private collection back in like Victorian times or something and the rest is history.  Their ubiquity in Strawberry Hill has seen them nicknamed "green pigeons".  

I saw a Japanese Minka house.  These were made of wood and ridiculously versatile and durable.  



I saved the Evolution exhibition for last.  It was cool, though some prat had vandalised part of it.  It was full of fossils, ancient living species and models of ancient extinct species.  These Liverwort have been around for 400 million years - twice as long as the mighty Cycads!

A fossil

Aaand I'll put the rest on a side page, because there's bloody loads of them!  Suffice it to say that a great day was had and I'll be back there in the Spring.
