Ok have a spot picked out but a few problems I am facing are. Packing soil in is hard to this area I have to hike up a creek to get to. As mentioned soil is mostly brownish clay so it's hard pack. Soil is dry even though I am about 4 ft above the water mark. So I was thinking that I would pack in the following for each hole. Good soil mix Coco-Peat Growing Medium http://shop.horticultureguy.com/index.php?action=item&id=369 to help keep the soil moist in between hiking in to water and also keep the soil soft. remember I am having to hike in to this spot and it's not an easy journey so keeping things to a min is important. Do you think this will work well? Thanks mrgreen
