Anything I can jury-rig that will work almost as well, or should I stick with the spiker, which everybody says doesn't do half the job, but seems to open up the soil well enough at first glance.
Also, what would people recommend for a jury-rigged roller? I've tried a ten-gallon drum filled with concrete (okay, a boat anchor!), but it doesn't roll straight. Something larger, without the built-in angle, that I can fill with water? I can lean over and roll the mother, I don't need a handle.
