What is the best thing to use to dig a trench for my wire?
There is no need to dig a “trench” so to speak. A simple slit is all you need – then the wire can be easily threaded into this slit. There is absolutely no need to dig up your yard. We have found that the quickest way to dig this ” trench / slit ” is with a straight edged spade or shovel. A power lawn edger or trencher is ideal for larger installations and / or hard soil conditions. These units can be inexpensively rented from a tool rental agent locally such as the Home Depot.
