I've been on the Bobcat drilling holes and planting pine trees, Power pole pine trees. The vine support cables need to be Mucho Strong to hold the weight of a big crop of fat Muscadines. These old Power Poles that are on the ends are 5ft in the ground with 160#'s of concrete in each hole. The middles are not pulled on, just holding weight up so they do not need the cement. After a couple of weeks I will start installing the vine support wire.
