raised beds

Hi there, I’m building some brick raised beds on some concrete footings. I laid the concrete today and was just wondering how long I’d need to leave it before I can start building the wall? Also, how long does a brick wall need to cure before it’s effected by rain? Thanks so much

Howdy, The missus has somehow talked me into putting down some sleepers in the garden to create some raised beds. I will be using 20x10x180cm untreated oak sleepers and the soil is extremely heavy clay and slightly sloped along the length of the beds. I need some advice on the best way to lay...
