I liked the bulk package was cost effective for the big old oak we got out front. I didn’t like that every spike is a bit broken due to no separation and no cushioning. The box should really be sturdier cardboard and every spike should be partitioned.Anyway, it was nearly impossible to pound them in directly since the soils here in SoFl are hard packed. I had to use an old solar lantern spike to drive a pilot hole, then I found a piece of 1/2” rebar on the side of the yard so used that to create the pilot hole. After that they drove in ok.They do the job. The tree was trimmed way back in the winter and now it’s filling out really well. The small crumbs broken off can be ground up and used on the lawn or elsewhere. I should do another round but the spikes were packed up for moving.Only tip I can suggest other than pilot holes is that they seem to absorb moisture from the humidity here in soflo. So if not using up quickly, store in a cool dry location, not the garage, or seal tightly in a plastic zip lock. I’ll just make larger pilot holes around the young trees at new house so I can just push the softened spikes in without pounding.
