I've got a 10 foot spruce in my yard, nothing bothers it. Recently, I've put down evergreen fertilizer spikes. Ever since than, something has been digging only in the spots the spikes are, and digging 4 foot holes down to the roots! I've been putting the spikes back daily and covering the holes and every day the same behavior occurs. I've put down hot pepper and citrus spray that usually repels everything but it hasn't worked. The small evergreen shrub next to it has the same spikes and its left untouched. It's almost as if the tree is coming alive at night, LOL! I've went as far as to pee in a cup and sprinkle urine around the area to deter anything, we'll see if it works.
