Recycled lavatories

The other week at my ever-challenging and interesting plant design course at Capel Manor, we got to talking about environmentally-friendly gardening.

Now, I'll nail my colours to the mast here and say I'm not entirely organic - I've been known to spray bindweed with glyphosate when nobody's looking, and my most heinous crime is to Pathclear my patio and driveway every year which I will no doubt have to account for in the afterlife. However - five minutes of talking to my very knowledgeable classmates has made me realise there's rather more to it than that.

We were talking about gravel. I've got loads of the stuff here - on my driveway, on the patio, and under my cold frame. It's cheap and easy as pie to use, I buy big jiffy bags of the stuff every few years or so to top things up, and until now I'd thought that was a relatively neutral material, insofar as I'd thought about it at all: the RHS promotes it as a good alternative in its "don't pave your front driveways" campaign, after all, doesn't it?

Not so. Marine-dredged gravel is the worst of all: "harvested" by something akin to Spanish trawlers only much, much more devastating. They suck everything up off the seabed to a depth of a couple of metres, killing all marine life that happens to be in their way, then they clean, grade and sort the gravel and spit back into the sea what isn't needed. Incidentally smothering all marine life that happens to have wandered into the area in the meantime.

So - you avoid that like the plague, and source it as land-dredged gravel, right? Well - if you can get companies to specify where they get their gravel from - this is certainly better. But the amount of fuel it takes to suck the stuff out of the ground, sort, grade and then transport it where it's needed requires a few aircraft-longhaul equivalents of carbon a throw.

This was all getting me in a real gloom. I was already having a conscience about using paving to hard-landscape the area around my shed and greenhouse (the garden makeover is proceeding apace, of which more later). It's not just the (itself not very eco-friendly) paving: it's also the sand and the cement-based hardcore I don't like having to use. Now it turns out the so-called 'better' options like gravel actually aren't.

The 'green' alternatives to gravel - bark chips, recycled tyres or bright blue recycled glass bits - are either too hippy or too horrible to contemplate. Or they wouldn't last five minutes. And then I discovered the wonderful world of recycled aggregates.

This is basically some of our rubbish that would have gone into landfill but is instead crushed down and sold back to us as gravel-like surfaces for pathways and hard standing. Surprisingly, for what might seem like an obvious idea, it seems to be a bit new, so there aren't that many people doing it yet. Long Rake Spar, in the Peak District, does a gravel made of crushed building materials that looks pretty good (and very like regular gravel), but the one I really like the sound of is sold as Traxmax. It's ceramics, either tiles or bathroom suites (I wonder if it's sometimes avocado-coloured?) taken out of the local tip, hopefully cleaned up a bit, smashed up into little bits and delivered in a big bag. The best thing about it is that because the original ceramic was made of clay, once it's broken up it becomes a little sticky again - so when you put it down on your path and it rains, it bonds to itself and becomes a solid surface.

You get it from this company - the only supplier I could find - and it's not even very expensive. There may be a catch: but I'm going to give it a go and I'll let you know what it's like. And anyway, I kind of like the idea of walking over second-hand loos on my way down the garden.

Perfect partners #1

Ophiopogon planiscapus 'Nigrescens', Hakonechloa macra 'Aureola' and Pittosporum tenuifolium 'Silver Magic', spotted at Wisley on a frosty day.

(By way of explanation: We've been set an assignment for the Plant Design course I'm doing at Capel Manor to compile lots of plant combinations that we particularly like, so since it's going to take me all year to do, I thought I'd share them as I go along.)

Back to school

I started my new college course this week.

It's the Plants and Plant Design course, run by Capel Manor College - and I'm told they're the only ones in the country who do a course focussing solely on designing with plants (rather than general garden design, which in most colleges means a lot of stuff about paving slabs). It's one half of their full diploma course - the other half being their "Principles and Practice" garden design course, which at the moment anyway I don't think I shall take as I don't really want to be a garden designer. That's tantamount to heresy in some quarters, it seems, and I may yet see the error of my ways and change my mind, but right now I just want to learn about plants.

The first day was pretty much an orientation session - working out what we're going to do and when, where the library is, all that kind of stuff. We were initiated into the arcane science of plant idents - something I do day-to-day in my normal job, but not something which I've had to do formally before. This week it's Deschampsia cespitosa 'Goldtau', a couple of Persicarias, a Sedum and a rather floppy-looking Achillea ('Summerwine' if my memory serves me right). Plant names aren't usually a problem for me, but remembering all their various habits, sizes, tics and quirks is a bit more challenging - unfortunately the plants are chosen for you, or I'd use the opportunity to learn a whole load of plants I don't already know!

The course syllabus includes a visit to Great Dixter, another to Beth Chatto's, and a third to - get this - the Netherlands to visit some of the iconic gardens they have there (unfortunately not Piet Oudolf's, but fortunately Het Loo which is somewhere I've wanted to go for a very, very long time). Now this is my kind of school lesson!

End of term

I thought you might like to see my model...

No, it's not a random collection of toilet paper, cotton wool and lollysticks, but a state-of-the-art 3-D representation of a town garden. Oh, all right then, it is a random collection of the bits other people throw out, but I had a fabby time putting it together.

This was the grand finale of the Capel Manor Drawing & Graphics course, which finished today - or rather, today was the deadline for handing in the coursework, which I managed by the skin of my teeth (was frantically cutting up chopsticks with my Felco no 9s over breakfast to make the pergola legs). It wouldn't win any prizes, but it's such a long time since I made anything like this that I just had a blast.

The whole course has been a bit of an eye-opener, in fact: can't believe it's finished already, it's gone so quickly. I discovered that I'm not all that good at drawing, though can turn out a passable stab at something recognisable if coerced: but much to my surprise, I do really like graphics, especially the pen work which is fiddly but very satisfying. I think it had a lot to do with being able to see the point of things - being a very prosaic sort of person, I could happily sit for hours drawing Very Precise Circles for planting plans whereas I got a bit impatient with all that painstaking shading and "just let yourself free" arty-farty stuff.

I was reading a recent issue of Gardens Illustrated (one of my favourite magazines) which has a column by the novelist Frank Ronan in the back (ashamed to say I've never read any of his novels, but he can sure can write about gardening). One of his last bon mots on the subject of "what is a garden" was "The gardener starts with a plant, not a pencil."

Precisely.

Drawing conclusions

I've spent a lot of time drawing lately.

Last night I was drawing an onion. The other day it was my hand, closely followed by a large director's chair on a table.

What this has to do with gardening I'm not quite sure - but all I know is it's great to be the one nicking the pencil sharpener out of the kids' art box for a change.

It's all to do with the Drawing and Graphics course I've now started at Capel Manor. Lovely teacher, great fellow students (all of whom are well into gardening so I now have lots of new friends to discuss the pros and cons of coppicing eucalyptus with), and I'm learning a great deal about negative space, tonal drawing and the value of a 4B pencil.

Can't quite see the connection between director's chairs and garden design yet - but am willing to suspend my disbelief for the luxury of being given permission to draw pretty pictures and call it work.

Crossing over

It's not often you find a gardener who's a designer. Or, for that matter, a designer who will readily admit to being a gardener: the best ones will usually be keen gardeners in their own gardens, but professionally there's not much cross-over between the two.

As time goes on, though, I'm finding the lines are becoming increasingly blurred for me between professional gardening and designing. I've had two regular clients ask me to design their gardens, or bits of them: one is a clear-ground project which will probably take years as we're doing it mostly by hand; the other is a perfectly good garden at the moment which they're about to rip up for an extension, so it'll need a re-work afterwards.

What's more, a designer I sometimes work for as a gardener has now asked me to help her out and design part of two of her clients' gardens - they've asked for veggie gardens and she doesn't know much about vegetables.

So all of a sudden, I find myself being a professional gardener and a designer.

Well that got me thinking. I actually really enjoy designing with plants - not so keen on the concrete and garden furniture bit, but love the idea of putting my favourite plants together so that they really sing. I've started to wonder if I might be able to break the mould a bit, and wear two hats at the same time - professional gardener, and plant designer.

To that end (and so that I'm not entirely talking out of my backside when asked to do these projects) I've signed up for a college course at Capel Manor College in London. This is one of the better design colleges, and to its great credit has a garden design course that concentrates solely on plant design. I'm starting by learning how to draw (never a great strength of mine) - first lesson at the end of next month. Wish me luck!
