Our soil is wet and moist most of the time. Landscape staples didnt work with the field fence apron that I like to use. I ended up using pavers to hold the fence down and it worked great. I removed the pavers after the grass grew through the fence.
We have all the diggers here. So far so good, no losses.
The only predator that has really given me trouble are rats and mice. It was a 3 week battle of the ages last year (it rained every day...deluges, record rainfall) but I finally beat them back. I'm still proactive in eliminating them. This year has been a good year, only 2 or 3 kills and we had more deluges...two days partly sunny, 5 days straight rain during the summer.
The only thing that probably couldve stopped them wouldve been hardware cloth enclosed pens and aprons. However, we know that would be too cost prohibitive. Ammonia and rat poisons are cheaper.
