I took off the corner poles and side poles so I could change them out
with the Tre Gai (vietnamese) bamboo I bought from
Safari Thatch and Southern Bamboo....both great companies and guys.
I've sealed the pressure treated lumber with a cedar stain that both
weatherproofs and makes it beautiful
Thanks to the advice of Garth from Safari thatch I used expanding foam (great stuff) to seal the bamboo on the open end. Besides sealing the open end it fills every nook and cranny and adheres to the 1" galvanized pipe I have mounted in the cement footing.
