For wider beds, build stepping-in spots large enough for a stool. Or better yet, build in a resting spot. A stump or large rock works great as a garden ornament, as a prop for your foot as you stand watering a bed or as a place for perching while you snip spent blooms or pull errant weeds. Speaking of weeds, minimize the time and energy you spend pulling weeds by laying down a barrier. I lay down 4 layers of newspaper in a new bed before I mulch it to keep weeds out and moisture in.
Irrigation is another garden saver.
With a drip irrigation system and a timer, I've made short work of watering and can get down in the dirt when I should. You've probably heard that getting there is half the fun. Before building a path, I think it's a good idea to measure the wheelbarrow or garden cart. A path should be wide enough so you can push yours along smoothly and navigate a turnaround comfortably. If you'll be pushing a cart, you'll want firm footing.
