I'm looking into planting some grapevines on our island. I have been reading several books from the library on how to go about doing that. One book, Vines to Wines seems especially knowledgeable and helpful. Part of the process is choosing a location and preparing the soil: so I am going to take some soil samples, and till up the dirt in preparation for next year's planting. In order to do this, I bought a rototiller off of craigslist.
