I'm probably the only crazy one that plants the bulbs 1 by 1! I have red clay, so it's really hard to dig deep trenches here. In addition, I over plant in areas where I already have bulbs.
I would try the trench method, especially if you have large areas to plant. Neal's info about the lasagna method also sounds easier than the way I do it.
I have found the bulb dibber to be a very useful tool, I can plant 300 tulip bulbs with it in 1 day. I also use bags of composted manure, and Bulb Food when I plant the bulbs, and they come up and bloom beautifully every year.
@gardengus, how many bulbs do you have to plant?
