The DW wants to put some small walkways in the garden. Some of the stuff that grows in there winds up on people's dinner plates. I think those are tomatoes in the middle of this pic. The fence is white cedar.
The walkway will probably be mulch or wood chips. I need a border to keep that stuff in. Like to use a lumber. Pressure treated (PT) doesn't have arsenic anymore, but must be some other nasty stuff to keep the bugs away. And probably leaches into the soil over time. My local sawmill man has some black locust 2"X8"s in a bin. Was thinking about using that. Supposedly, when buried, black locust lasts about half as long as stone. It's a natural product, just grows like that, seems less likely anything leaches out of it. Actually, I checked it out a few years ago. The local building inspector told me that The State of New Jersey rates black locust for 60 years, buried, in the ground. So, that's the minimum.
Slightly off topic, but I also built an Ipe deck some years ago. I notice the bugs (gnats, mosquitoes and such) never come near it. Works for me.
Any thoughts on the black locust in a vegetable garden?
