A native of Southeast Asia, elephant ear is hardy in U.S. Department of Agriculture (USDA) plant hardiness zones 8 through 11. In USDA zones 8 through 9, elephant ear usually dies to the ground, returning in spring once soil temperatures warm. In USDA zones 10 through 11, the plant is nearly an evergreen, according to the Floridata website. Partial shade is ideal for the plant, though with enough water it withstands full sunlight.
In your case my guess is your fence posts were taller than the fence, so your wood fence posts should be in the ground at least 3 feet. When it is time to install the fence post, be sure it is in line with the other posts and it is plumb.It is also important that the fence post is centered in the hole.Start to add the crushed gravel in 5-inch lifts.our fence posts have a tremendous amount of force against them each time the wind blows. You may not think a 5-foot-tall fence is high, but in terms of wind load, it is substantial. To get an idea of what I am talking about, lift a 4x8 sheet of plywood up and take it outdoors on a windy day.
Wood posts from 5.5 to 8.5 feet long and from 2.5 to 8 inches or larger diameter are readily available. The larger the top diameter, the stronger the post. Line posts can be as small as 2.5 inches, but larger ones will provide for a stronger, more durable fence.Corner and gate posts should have a top diameter of at least 8 inches. Brace posts should be 5 inches or more in diameter.teel corner post and brace assemblies can be used in place of wood assemblies. The steel posts should be set in concrete anchors. Corner post anchors should be 20 inches square and 3.5 feet deep. Braces are anchored in 20-square-inch blocks that are 2 feet deep.
