Corner Post For Garden
I live in Northern Minnesota and this March has been exceptionally mild, therefore I am thinking of my garden. We decided this year that we were going to expand our garden and make it look nice (as well as keep our dogs out). I have been contemplating different types of wood corner posts and its driving me nuts! Here were the options I have been looking at:
White Cedar - good for outdoors, durable, but now over-harvesting and deer now basically have made it unsustainable and not a good option. Also the fact that a 4x4 is around $17 is a little bit detouring.
Pressure Treated Wood: Durable, can be outdoors, but have terrible chemicals, probably not good to be in a place where we are gathering food, and just not a good appearance - but it is cheap
Pine: not the best outdoors, but local, cheap, more sustainable.
Pine is what I would prefer to use for all the above reasons, but everyone says it does not last. Is there a way to make it last? Is there a type of wood I am missing?
