i have tried in vain to grow carrots again this year over the lotty to no avail
 i am planning to use raised beds at home each is 15inches deep and 10ftx 5ft how much sharp sand should i add for carrots

[Yorkie]

Are you using soil or some sort of compost in the raised bed?

If soil, where has it come from, and what consistency is it (sandy, clay, loam etc).

i grown my carrots in raised beds and large bins.....

50/50 sand and good NEW topsoil which I bought in by the cubic metre.... ie 1 cubic metre of sharp sand mixed with 1 cubic metre top soil - it works a treat..
