While this is correct you cant have them sitting in water through out the year.Postby Hector Johnson on Today, 22:28
Swamp Cypress do very well in water. As I recall, Steve Rawkins keeps his in water for 4-6 months of the year.
They're called "Swamp" Cypress for a reason.
i have found good results to have them in water up going a good inch up the trunk during winter, then come spring add some fertilizer to the water and allow it to fall over time. During summer, I have had only the first few mm in water.
I have done it for two seasons now and since I got the tree which was about the thickness of a pencil, its now about 3 inches.
But its good to see that although I was knocked back the first time I brought this up, it was back up later then believed...
