In the summer of 2010 I expressed my dislike of clearly visible corten steel edges in restored or recreated garden parterres. In a comment to that post some very good suggestions were made to better conceal the steel rims (by either letting the young plants grow a bit, or raise the level of gravel). My chosen example of Het Park admittedly consisted of only young planting at the time, so the suggestion that these parterres needed more time to fully mature made sense.1The corten steel in Het Park is still ugly, by the way. Four years of maturing has not helped at all. The same comment suggested it would be almost impossible to spend so much money on corten steel edgings, just to have them disappear completely. I think that is hardly an argument to create something visually unappealing.
I still don’t think these edges are visually appealing, so I was curious how Het Loo would deal with this issue. Here they restore, replace and recreate the parterres surrounding the house. Initially forced by box disease and a leaking irrigation system, but also inspired by new insights and knowledge, resulting in markably lower and thinner hedges.2A few images pointing in that direction can be seen here: Cascade weblog. The last phase of that process has begun this September, thus ending the unique combination of newly restored parterres in the west half, and the old parterres in the east half of the lower garden, that could be seen this year.
So. How does Het Loo conceal the corten steel rims in their parterre? They do not.
In fact, Het Loo takes the whole thing two steps further by not only displaying these rims in full sight, but by also using them as guiding rails for the cutters. A ‘slider’ is attached at the end of a stick, on which either a vertical or horizontal cutting blade is mounted. This slider is placed on the corten steel edge, which thus functions as a rail.
The cutter is switched on and the gardener commences his stroll among the hedges: parterre hedge clipping 2.0 in full swing.
The result in the Koninginnetuin (recreated last winter) looks like this (click to enlarge).
Hedges end well within the confines of the steel boundaries. Because this vertical rim functions as a rail, and the distance between rail and hedge is fixed by the way the cutter is constructed, this is how the parterre is going to look ‘forever’.
The hedges will of course mature and fill up more, but there is no room for them to gradually grow beyond the set width and (maybe) cover the steel. The soil and gravel can’t be raised to level with the edge of the steel rim, because that would compromise the smooth running of the slider guiding the cutting blades along the hedges.
This is it then. These eyesores are here to stay, clearly visible and more out in the open than ever. Practical reasons for doing so have clearly won over the -well: my :-)- aesthetic preference of experiencing a garden without having the actual construction of garden elements thrown in one’s face; and without seeing the tricks which enable gardeners to maintain the garden’s well-kept image.
Aesthetics is just one element of gardening. The cost of maintenance is (and has of course always been) an important factor. And let’s not forget about some health issues that gardeners at Het Loo will not have to face anymore, because they can keep their backs straight while clipping some 25 kilometers of hedges.
