I use wide, double-dug beds. To decide how wide to make my beds, I crouched down and measured how far I could reach. The width of my beds is about twice my reach, so that I can reach the center of my beds without walking on them (I can reach about 26 inches.) For the paths between my beds, I leave just enough to stand or put a bucket in the pathway. It's only about 14 inches wide. In my favorite out-of-print Rodale Press book, they use a space-saving example of 1 ft. wide paths and 5 ft. wide paths. It sounds kind of crazy, but the difference between a 4x25 ft. bed with 2 ft. paths and a 5x25 bed with with 2 ft. paths is 25 square ft. You can get a lot of veggies out of 25 square feet! I have a wider access path, too- about 3 ft. wide, in front of my gate.Â

I clear the weeds/grass with a digging fork. Then I spread compost or composted manure. I try to add at least 1 cu. ft. per 25 square feet and it can be just about anything, from $1 bags of manure to $3 bags of compost to free rabbit, sheep and llama manure. I use as much free material as I can get, but this still ends up being one of my biggest expenses. If you can get rabbit manure, that stuff is worth its weight in gold -- no weed seeds like you might get in horse manure, it's not hot so you can use it fresh, and the plants LOVE it. Really, though, ANY manure or compost is good -- just be careful that any poultry manure is aged so that you don't burn your plants. Then I double-dig the area (google for lots of tutorials on that. It's important to have the right moisture-level in your soil to do it right, so this might mean waiting after a rain or watering and then waiting if it has been dry), rake the bed, and plant.Â

Lasagna gardening sounds good in theory but I run into two serious issues. First is logistical. Where/how to get all of that organic material to layer on my beds? How to get it home without a truck (and with my van full of kids?) Even if I can manage to get that much stuff for free, how much will I spend in time and gas to gather it all? It requires a good amount of material all at once.. My other problem is weeds. I have a couple of serious, hard to eradicate perennial weeds here -- crabgrass, bermudagrass and nutsedge. The first two, especially, are what I concentrate on removing, roots and all, before starting a new bed. With my digging fork (digging around with my hands) I really work hard on getting them out before planting seeds, or they'll over-run everything -- even with a heavy layer of mulch over them. (I've tried...)

Wooden sides are pretty and all, but even the cheapest wood isn't cheap. Double-digging wide beds gives you most of the benefits, for just the price of your labor. I use pretty intensive plant-spacings -- similar to SFG for the most part (but I don't treat the plants as squares. They're circles. By off-setting the circles instead of planting on square grids, you can plant even closer. )
