Raised bed newbie advice
I want to buy some raised beds and I'd like to be able to easily grow any veg in them.
I was thinking four 3ftx4ft raised beds but I'm unsure on how deep they should be?
The ground is turfed. I assume I need to remove the turf underneath?
The ground underneath is rocky.
Are those beds made from decking ok or is using decking a bit of a fad?
How long should a tanalised bed frame last?
Do they need lining?
What type of soil should I fill them with? Should I use different types of soil for different veg?
Any recommended national companies to buy soil from?
Sorry for all the questions :-/
