At last my raised beds are done and ready for the compost mix..

My question is how much mix do I need??

What does a 8' x 4' x 18 inches high raised bed take?

If anybody have any suggestions of what and where to get a very good compodst mix I would welcome your suggestions.

Thanks in advance,

Ray.

That equates to 1.4m3 by volume and getting close to 2.5 tonne. Additionally you will find that it will self compact over the next few months so you will be constantly topping up. Have you ever dug a hole and managed to put back in exactly what you took out of it? Soil bulks up by a factor of approx. 1.7 and that is why you will never fill that hole due to the air spaces. So at a guess you will only get in a little over 1m3 at first and the rest will be topped up later on.

If you want advice on what to put in it and where to source it then that subject has been thrashed to death only this week on this forum. Check out a thread started by caz87 called raised bed compost filling in the vegetable/allotment section.

@ Ray and Fiona, Any updates or photos to show us if your raised bed project is finished? How much soil did it take in the end?
