Ideas and observations – part two of two.

Palm trees are iconic in the south of France. There are only two native palm trees but imports are now the backbone of the landscape. Alas, the red palm beetle (Rhynchophorus ferrugineus) is likely to change that. It only arrived in France in 2006 but is so rampant that it is cutting a swathe through the trees and killing them. Many have been removed.

Dead palms in Perpignan which is across the other side of France but I saw plenty in the Riviera, too.

Apparently, it is possible to spray for it but as soon as the spraying stops, it returns and spraying tall palm trees must require a cherry picker and some heavy-duty insecticides. A horticulturist told me that the only hope for the future is finding selections that are resistant to the palm beetle. We may rail against our border controls here and in Australia but oh my goodness, this is another destructive pest that we don’t want hitching a ride here. What will the Côte d’Azur be like without its palm trees if the beetle is left unchecked?

Vetiver grass products

I have only ever seen vetiver grass used in this country once and I admit I was surprised our biosecurity even let it in, given that it can put its roots down to four metres deep in the first year alone. It seems that its abundant production of leaf blades can be turned to good use and there is not much danger of running out of raw material. I saw these on a market stall at the cherry festival in Céret, near the French border with Spain. They were very charming but comparatively expensive. You don’t have to have vetiver grass to make something similar. It occurred to me that, were I still of the craft-y persuasion, some of our native grasses with leaves that have some substance – Chionochloa rubra and Carex buchananii come to mind – would likely work just as well. I had a friend who was keen to try weaving with pine needles and I sent her some of the exceptionally long needles that fall from our Pinus montezumae. But she never sent a photo of the finished product so it may not have been as successful as she hoped.

The cherries may not have been up to much but how charming is the little town of Céret?

Sadly, I have to report that the cherries at the cherry festival were a disappointment. After an unusually wet spring, they were watery, splitting and lacking sweetness, bearing no resemblance to the fleshy Black Dawson cherries I pay an arm and a leg for in season here, but there were plenty of them and the French do street festivals very well. They do love a brass band – or four or five of them on street corners in this case.

The graceful design of split steps
And a smaller version, also from the Ephrussi de Rotshschild garden
We could have done more with these casual steps, had we thought of it at the time.

In the Ephrussi de Rothschild garden, the Baroness who created it clearly liked split steps. There were at least three, maybe more. If you do a net search for split stairs, also known as bifurcated stairs, you will see many examples in internal situations, mostly from USA and in modern, opulent homes. I have seen them used externally on grand old villas in Italy and always thought them particularly graceful. Executed in stone – or even concrete – they are a feature in themselves which would not be appropriate in our more informal garden. It is the form I like and there is no reason why they could not be constructed in a more naturalistic style. I am rather regretting that we never even considered something more ambitious for steps in our garden. You need gradient but also space and I am pondering where we might adapt some steps to try an informal version.

Synthetic screening in Nice
Presumably a cheap and nasty domestic version, already threadbare and dropping synthetic fibres onto the ground below.

The French do many things well but these ghastly synthetic fences and screens are not one of them. No, no. Just no. They are really awful, both visually and environmentally. People lacking all aesthetic sense seem to think that the blue tones of synthetic green will ‘tone with the environment’, on account of being green. I see the same thinking down at the new roundabout finally completed where our country road joins the state highway. I get that the landowner who lost the corner of their property wanted windbreak but did it have to be so very high, built like Fort Knox but in tanalised timber and then wrapped in synthetic green netting? Black would have blended with the environment much better. Still ugly, but utilitarian ugly, not an assault on the visual senses.

No, that green netting does not blend in visually, in New Zealand as here, or in France.
Stopped by rush hour traffic by a decidedly extraordinary commercial building

Also related to assaults on visual senses, these two commercial buildings in and near Nice were impossible to miss. I am sure they are as controversial for locals as for visitors.

I had to photograph this second one from a moving coach so you may miss the fact that the head looks mighty like it was modelled on King Charles. The similarity was unmissable. I am surprised it hasn’t  sparked a fresh outbreak of the Hundred Years War of old.

Outside of tourist areas, much of France closes on Sundays. We wandered through the near-deserted city square in Perpignan where all the outdoor furniture remained outdoors, albeit loosely tied to make it clear they were not free for the taking. Just as I marveled at the use of ceramic pots with topiaries planted in them to block off a road (instead of traffic cones?) in Malaysia, this level of trust in human decency and good behaviour made me ponder where we have gone wrong in this country.

Pinus montezumae may be suitable for weaving into craft-y baskets.

Stepping up and stepping down

floating or suspended stepsThe floating or suspended steps with no visible support structure are a common feature in modern interior architecture where a lighter look is desirable. I can’t recall seeing them used in a garden before and, to be honest, I am not sure they add a great deal to this particular scene. But I did photograph it in a place with a large budget where the owners and designer could clearly afford such attention to detail.
??????????????????????????????????????????????????????????????

Wide steps, beautifully constructed, link two different levels of the same garden (Mount St John in Yorkshire). It is the generous width of the steps and the gradient which make this look more graceful than the inset photograph from Scampston. The gradient is sufficiently gradual to enable the use of a lawnmower alongside and to avoid the need for the decidedly utility hand rails which detract from the other steps.
003These are the classic steps which are attributed to the great architect Edwin Lutyens during the time of the Arts and Crafts movement at the turn of last century. A central circle has inwardly curved steps on the upper side and outwardly curved steps leading downwards. Good design does not date. Good construction also lasts the distance.
???????????????????????????????These steps have the outward curve only, but I chose them because they are an example of dry climate steps. The narrow strips on the treads are actually terracotta tiles placed on their sides. The look is detailed and attractive although I imagine it would be expensive to do here Both clay brick and terracotta will become moss-covered and very slippery in damper climates like ours. Note the care and precision in construction.
???????????????????????????????Not every set of steps is going to be a precisely engineered work. These were clearly DIY, although access to flat slabs of stone for the treads gives the impression of permanent quality. Look at the risers – some are local round stones held together with cement. In the absence of suitable stone slabs, check out the modern concrete pavers on offer. These can be cut to size and the finish can be good enough to deceive most eyes.
???????????????????????????????No matter what material you choose to construct your steps, there are well established guidelines for measurements. For comfort, the gradient is less than internal house stairs. Step risers should not be more than 15cm high and the corresponding step tread around 30cm from front to back. There is plenty of information on proportions that work best. Generously wide steps usually look more gracious than tight, narrow steps where space allows.

Gardening on a steep slope

Terracing allows for easier gardening after the initial cost and effort (but I think the steps are too steep to be comfortable)

I had a few days in Tauranga last week. It is always interesting for me, a country dweller, to stay in city suburbia. It reminds me that others garden in very different situations. In this case, I was staying with my sister who lives on a relatively steep hill and that certainly brings a whole new set of challenges for gardening.

If I was starting from scratch on a steep section, I would get wide steps in first and then start working around them in terms of the garden on the sides. Where space allows, wide steps look far more generous and remove much of the off-putting aspect of a steep slope.

Where space allows, wide steps look more generous and less onerous to climb

There are rules for garden steps. The DIY home owner often makes the mistake of getting the tread width and riser depths wrong. The riser is the vertical piece and the general advice is that in a garden situation, it should not be more than about 15cm. To balance that, the tread (or flat part of the step) should be about 30cm. That is a gentler gradient than indoor house stairs. There is plenty of information around on this topic and it pays to take notice. The hand hewn steps in my sister’s garden were probably the other way around and very difficult they were to negotiate as a result.

If you decide to do a zigzag path crossing your section rather than steps, take the time to get the path almost level crossways. Most of us have two legs the same length. It is not at all comfortable to limp along a path that slopes sideways as well as wending its way up or down a bank. I say almost level. You want your path to shed water sideways rather than channelling it down the length so you need just a slight gradient across. Get the spirit level out.

Once the steps or paths are in, you can then decide what you are going to do with the sides. It is difficult on a steep slope. If you are a serious gardener, you will probably want to put in terraces. If you don’t, you are going to destabilise the slope every time you dig into it and the rain will wash the soil downhill. It is also physically uncomfortable to work perched on a steep angle.

Just remember that if you terrace and sow lawns, you need to make it easy to get the lawnmower down. If it is too difficult, you will keep putting off mowing the grass.

Weed mat is never a good look

Weed mat is never a good look

If you don’t want to tackle the effort and expense of terracing – the hard landscaping, retaining walls, finding topsoil to fill your terraced areas and the rest – you may choose to let nature take over your slope. One hopes not many of you will think it appropriate to clad your slope in ugly weedmat. That is a truly awful finish. In shaded areas, allowing ferns and mosses to colonise gives an attractive, natural look over time.

In sunny areas, you will need to give a helping hand. Whatever your opinion of agapanthus, it does a great job of retaining clay banks with the bonus of summer flowers. Alternatively, there are a range of sedums and sempervivens that you can plant and leave to smother a dry, sunny bank. Or you can establish our native iceplant (horokaka or Disphyma australe) which evolved to cope with these types of conditions. Renga renga lilies (arthropdium) prefer a little shade but will tolerate full sun and will grow in inhospitable soils.

A bare bank will erode so you need to stabilise it with something.

Professionals step fences to get them down slopes

I would also observe that fences can define your station in life. A DIY fence often follows the lie of the land, undulating its way down the hill. A professional fence steps its way down. That is all on that matter.

The DIY fence is often obvious by its undulating line, following the contours

I admit that I leaned on the decking railing at my sister’s house and looked at her steep section which runs down to a native bush reserve and then an estuary. I looked at my sister. Confine her gardening to the flatter, more accessible areas immediately by the house, I suggested, and let the lower slopes revert to bush. She will keep her lovely outlook without having to do major construction and continual garden maintenance on a difficult site. I think it likely she will heed my advice.
