Plant three to five papaya seeds in each pot, about 1 inch deep and 3 or more inches apart from one another. Set the pots out in an area that receives full sunlight. Wait two to five weeks for the seeds to germinate. Choose your outdoor planting site, which should be in full sunlight and in a warm area of the yard.
The two horizontal lines in the lower half of the plot represent two criteria for specifying the lifetime of a tire. The lower curve represents 2/32, the legal limit in most states for minimum acceptable tread depth and the height of tread wear indicators built into the tire. This depth corresponds to the common Lincoln head penny test. The second line represents 4/32, a depth that may represent a safer minimum. The first plot shows the actual measurements of the tread thickness. I've had the tires rotated twice and there's an obvious change in the wear rate at each rotation.
Once the concrete stair treads are installed, people have a safe and permanent egress from inside and outside the structure. The standard size of a concrete stair tread is 24 or 48 inches by 14 inches with thicknesses dependent on the tread profile. These edge profiles include bullnose, wedge, square, and dropped. The bullnose profile has a thickness of two inches.
