help with designing raised beds
I've been using large storage containers with holes drilled in the bottom cause it's the only method of container gardening that was an option for me.
NOTES: I apologize if some of the questions are dumb, but I've never grown in raised beds, nor built them. Some of the designs are similar to SFG boxes, but they are NOT boxes. Please don't refer me to that forum; I apologize if this comes off as rude, this is merely preemptive.
I'd like to do raised beds, but I don't know how to build them; I'm not a DYI person my brain just isn't wired to think that way.
I know the basic dimensions, they'll be 8' x 12'.
However I'd like a good depth for the ones that will grow root veggies; 12"-24".
I have an idea for how to design the raised beds for root veggies, but I don't know how to execute it. I'd like the bed to be divided up into 4-6 squares.
Each square would have one root veggie grown in it. I'd like each square to have a depth in the range specified above.
Another design I'd like to consider is raised beds that are 'stacked' or are designed that they look like stair steps.
I'm not really interested in the cosmetics of how the beds themselves look, but rather they save space and stretch it out.
What materials (besides wood, nails, and a drill) would you need to build raised beds? Also what type of wood?
I plan to put bottoms on the raised beds, will the bottoms need to have holes drilled for irrigation?
