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.
Tie the string to the opposite end or corner post, and then mark the posts at the string line and cut off the excess height. This step works for fences on flat surfaces; fences on slope install with a step pattern, so you need the extra height until you install the fence panels.et 4-by-4-inch posts 18 inches deep in the ground and spaced as far apart as the fencing panel width. Set the posts in compacted gravel or concrete for extra stability. Place a level on the sides of the posts to check for plumb and adjust as necessary; wait 24 hours to add the fence panels.
