Has anyone had any experience growing plants and stuff like that in tea chests? There's a bit of the garden, at the back, by the fence, that is paved but is of no real use (no point sticking a bench there as it will only get the sun in the morning) and I think that getting, maybe 4 tea chests and half filling them with some sand, rubble and soil (in layers) and planting plants that don't need much sun there would be a quite funky. I would put, in the furthest corner, one te chest on top of another and then two in front of it. suppose I'd better punch some holes in the bottom, and raise them ever so slightly to prevent damp problems, but I think it's be a gem of a idea and possible.
Work out what you want to put in there, first. Find some plants you like that appreciate shady positions, and then work out what soil you need to grow them in. Adding sand and certainly anything larger (typically you'll just want a few pebbles/crocks at the bottom to help drainage) is only really necessary if you want things that are very intolerant of damp conditions - so in this country that really only means alpines and the like. Definitely don't do layers - plants very much won't appreciate their roots being in a layer of nothing but sand - because it has no nutrients and totally fails to retain water.
Cheers, boss. I've found some tea chests on Ebay, 14 of them, in London, so I'll be able to have a few practice runs (and the rest can join this fucking fireplace). I'm just worried it might look a bit tacky, but for the money, it's better value than a proper planter.
