Over the past few days we have cleared a neglected border alongside one of the outbuildings and have been left with a dry, narrow bed. The soil is very shallow and impoverished, so it badly needs to be improved and, if possible, made deeper.
Our plan was to add edging that would enable us to increase the depth of the soil, but none of the options available from local establishments were particularly attractive. We did, however, notice that galvanised metal, particularly corrugated, galvanised metal seems to be very popular at the moment. Many of the garden centres and nurseries are displaying vast arrays of galvanised metal containers, both new and vintage.
This must have tweaked something in my subconscious as I remembered that we had a few small sheets of galvanised, corrugated iron sheeting up in the orchard.
I grabbed one, and after a couple of measurements I realised that, if I cut it in to 8" wide strips, they would be perfect to form an edge to the border. They would also allow us to add compost and manure, raising the soil level, improving both the soil quality and its moisture retaining ability.
After twenty minutes with an angle grinder the 24" by 30" sheet was cut in to four strips and I was ready to try out my design.
It worked beautifully. The strips of corrugated iron don't reduce the width of the bed and they interlock, making them simple to install and tie together. The corrugations also add rigidity, so we will be able to add compost and manure, increasing the soil depth without fear of the edging collapsing.
The edging looks great alongside the brickwork and I am feeling quite pleased with my low cost, up cycling solution.
