yer they will rot from the topI sometimes wonder, if chard or burnt posts would be the answer.
If you could buy pealed blank posts, stored dry, then point them yourself, and use the point off cuts to have a fire, then lay the post bottom half end on fire, rotating once after 20 minutes, then remove after 20 minutes and dip in water for 5 minutes.
Chard Wood is meant to last 50 plus years,
Any thoughts ?
