I have just spent a couple of hours at the table, whilst 'she who must' is out at Pilates, stripping some heavy-ish copper wire out of the plastic jacket. With a Stanley knife, it becomes a simple a task as peeling off layers of sunburned skin ! As satisfying too !
So, in a couple of hours, I stripped off about 50 metres plus, of good gauge shiny copper, into 150mm strips, dropped them into a box, and have started using them as slug deterrent around the brassica plants, and the marigold family in our front garden.
Keeping an eye out for stuff in skips where a house is being renovated, re-wired and modernised can be so rewarding. Old fashioned plumbing , lengths of piping, replaced windows, are all treasure. I salvages three good sized water tanks capacity of 200 litres each last year, and 600 ltrs of more valuable water is not to be sneezed at !
Those council boxes for re-cycling bottles are good too ! Fill them with growbag stuff, and they grow very nice well protected carrots, peas, runner beans and wotnot !
