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.
Drive or auger & tamp both end posts (or corner posts) for the run you are fencing. Concrete or gravel may be used. Do not concrete within the top 4 inches of the ground. Posts should be set with 4 feet, 6 inches above ground and 3 feet, 6 inches below ground.Wet or sandy soils may require 5-6 feet in ground. Establishing the fence grade: Tie one end of a guide wire (12 Â½ ga.nstalling line posts: Set line posts at 10- to 15-foot spacing unless you are using high tensile fence. High tensile can be 15- to 20-foot spacing. Post spacing will be determined by terrain, type / size of post, bends in the fence and animal pressure. T-posts: weight should not be less than 1.25 lbs.
