We live out in the country. The ditch in the front of our property is very deep. We are unable to cut it with a riding mower as we do the rest of the lawn. Using a push mower is very strenuous. Weed-whacking is almost as impossible. We have thought that the only way to maintain the ditch would be to burn it down, but we want to do it safely. Does anyone have any good suggestions on how to burn the ditch down without causing damage to the property or to ourselves?
