Builders' sand for drainage?
In article ,

They don't wash it at the quarry, and that's where I get mine from. I'm a bit hazy about the geology side - I guess sand comes from both sea and river sources, so if former it would surely have traces of salt in it? But I must admit, I've never licked it so can't say. When laid down, sea sand would contain salt, but almost all sources will have been washed clean. There is probably salty sand in the UK, but it will not be sold unwashed by respectable builders' merchants, as the salt interferes with cement and other uses and salty sand does not meet the relevant standards. Obvious, when using sand for seriously sensitive plants (e.g. orchids or carnivorous ones), it should be well washed. Most plants don't mind a trace, and quite a lot can handle actively salty soil if they are soaked when they are watered. Regards, Nick Maclaren. |
