Need your collective wisdom please.
There is a narrowish strip of earth (approx 9 inches) between the dege of my garden path and neighbour's fence.
Garden is long and narrow - approx. 126 feet.
Strip is not exact same width for full length.
Landscaper filled in the strip with gravel chips and we top dressed chips with small cobbles (bit bigger than a hen's egg).
All looked lovely until......squirrels have now practically stripped the full length of path of the cobbles.
They bury them in the lawn and sometimes just skip off with them taking them to God knows where.
Anyone cast any light on why they do this, how can I stop it and, if not, any other recommendations for filling in this narrow strip with material that will be of no interest to squirrels.
Thank you.
