Our tyre wall progresses!

    We are building this rammed earth, tyre retained wall (note all materials saved from landfill!) to keep train noise out of our otherwise peaceful site! It looks a bit crude at the moment (although not as bad as I had thought), but we won’t stop here. The inside will be plastered with an earth based plaster onto some sort of mesh, with a little overhanging eaves to keep the worst of the rain off. The outside will be planted. Into each triangular space between two tyres, we will pack topsoil (the insides of the tyres are filled with rammed subsoil), retained by wire mesh. We need a great variety of plants, as (but not limited to) the following: . drought tolerant (conditions high up the wall may well be fairly dry for much of the year) . hardy – will be exposed to wind in winter . lots of foliage – both to hide the tyres, and for added sound reduction . evergreen/winter cover – see above . no maintenance required – inaccessible . indigenous . good for wildlife. . self propagating annuals . perennials that spread, but not too rampant . range of sizes . not needing rich soil – tyres mainly filled with sub-soil – topsoil limited to ‘pockets’ in the wall – see sketch. (that’s enough characteristics – ed.) For an idea of scale, we have more than 30 metres of wall, around 1.8 – 2 metres high. doing the numbers, this means around 450 triangular pockets of earth (say 20 cm each side, and 20cm deep: roots can get into the soil inside the wall as well), and around 45 tyres along the top. So we need a great deal of variety – partly to make it look good, partly to make sure that there is variety to cope with some inevitable failed choices and varying weather conditions, and partly to be a haven for wildlife – once built, there will be no reason for people to be on that side of the wall. We are keen to get some plants in asap – so that we have something to show this summer. Any ideas? Want to get your hands dirty?
