I have found a number of spoons and 2 bottles of Patchouli Oil in the veggie garden this year. The first bottle of patchouli didn't phase me, as I have left it there for maybe 10 years - It just fell off the fence where I leave it. But I didn't know I had another bottle buried. I use it to keep mosquitoes away. Go figure, I am chemical sensitive to bug repellants and allergic to some of the natural ones, but Patchouli....
I don't wear it around others though. It is a love/hate smell.
All of my hand trowels are missing. The flat shovel we edge with is missing. I think maybe my son gets too tired when he is out landscaping and leaves them at the last job? Dunno. He is a crazy hard worker and will keep going sun up til after dark. Some things may be under the CRV seats. We share the vehicle.
Mostly, I bury the silverware (stainless) and find steak knives stabbed into the ground where I cut some squash stems.
