Quickly-growing in a columnar manner up to 20 feet tall and spreading by roughly 6 feet is the Mexican Fencepost. They tend to grow over 3 feet in one year.
Native to Southern Mexico, these cacti require little watering, love full sunlight (and tolerate intensified heat well), and are cold hardy to roughly 20 degrees Fahrenheit.
Mexican Fenceposts have medium-sized, white thorns and produce low amounts of litter.
As with many other cacti, these are prone to attacks from scale insects, especially if in the shade. There are no known effective measures that may be taken to prevent scale insect attacks; however, EnviroControl does offer services to remove them and help the cactus recover from such an attack. They are also prone to rot if soil remains too moist, or if in the shade.
The Mexican Fencepost has been used, as the name implies, as a natural fence. It’s an effective natural security barrier and screen. Additionally, these cacti produce greenish-pink flowers that bloom from March into April, and then become edible, dark-red, very sweet fruits.
