Living Cactus Fences and The Hardy Mexican Fence Post Cactus

(On SALE October 2017 – 40% OFF!)


The deep green, columnar trunks of the Mexican Fence Post catches the eyes. So much so, some would say it’s a good lookin’ cactus. The cactus develops stout, cylindrical stems with ribs over its lifetime. The Mexican Fence Post has mini-spines, so it is easy to handle when planting.

Pachycereus marginatus, the Mexican Fence Post cactus, developed its common name because in many towns in Mexico it is used to construct a living fence, often along roadways. The Mexican Fence Post is native to the states of Hidalgo, Queretaro, and Guanajuato, and is widely planted throughout Mexico.

When in bloom (usually summer) the Mexican Fence Post has pinkish-red flowers that are very showy and add great color to your landscape. Following flowering, the Mexican Fence Post develops spiny, red fruit with black seeds.

In your outdoor space, it’s great as an accent or main feature; plant it close to a tall wall as a vertical accent, or create a living fence from cuttings of this plant. It can also make an excellent potted indoor plant if you have an area with bright light. 

Caring For a Mexican Fence Post Cactus

After you purchase your Mexican Fence Post, plant it in well drained soil and full sun. Partial shade is also sustainable (especially in the Mojave Desert.) The Mexican Fence Post is drought-resistant, but likes occasional water during the hot, dry months. Allow the soil to completely dry out between irrigations. The hardy Mexican Fence Post is able to sustain temperatures as low as 25 degree Fahrenheit. You can protect the tips of the plant in the winter to keep them looking healthy. If you are in a frost prone location, you can cover the tips with Styrofoam cups to protect them in the winter months. Or, you can wrap it in a protective fabric (burlap or Agra-wrap.)
