P
Pachycereus Fulviceps, Cardón
Pachycereus, a small genus of about ten species of cacti, includes some of the largest specimens in the entire Cactaceae family. The single largest cactus ever recorded was a Pachycereus; more specifically, a colossal Pachycereus pringlei, or Cardon Cactus, which astoundingly grew over sixty feet tall! Massive though some Pachycereus may be, many of these cacti grow to a much more manageable size and are often cultivated in the American Southwest and Mexico, to which they are indigenous. The most common of these varieties are Pachycereus pringlei itself and Pachycereus marginatus, both of which can be shaped as a sort of fence or a feature in your landscape. These cacti have a columnar growth habit, with ribs on the stems and lots of treelike branches. Superficially, Pachycereus pringleiresembles the more common Saguaro cactus and is often mistaken for it. Like most other plants that can grow to staggering size, Pachycereus cacti grow extraordinarily slowly — over the course of hundreds of years — and require virtually zero assistance on your end provided they're raised in a desert environment. These magnificent specimens were once much more common, but many have been cleared or cut down. Nonetheless, entire forests of Pachycereus still exist in Mexico, and this stark and beautiful cactus is a delight to see in person: their spiny, alien, colossal shapes are a great example of the twisted beauty of which Cactaceae plants are capable. ? Photo via fineartamerica.com/ Growing Conditions Light: As much full sun as possible. Water: Overwatering Pachycereus is a surefire way to damage them. Arid, hot conditions just like the Mexican desert are ideal – you really shouldn't have to water them at all. Temperature: Their conditions should be as desertlike as possible, which means lots of very high temperatures. Soil: Pachycereus pringlei has developed the amazing ability to grow on rock without any soil present. It accomplishes this through a symbiotic relationship with bacteria in its roots, which glean nutrients from the rock itself and pass them on to the plant. If you're cultivating them in containers, potting soil is fine, but be aware that it may not even be necessary. Fertilizer: Also not necessary, although many cacti do benefit from feeding with a cactus fertilizer and fertilizing them certainly won't hurt. Propagation Like most cacti and succulents, these plants propagate by cuttings. Sever a branch and replant in well-drained soil. Make sure as well to stand the cactus up in an empty container to let its ends heal off before you replant it; this will keep its stems shaped right, and cacti with dried ends form roots more easily after planting. Repotting Inapplicable to most scenarios in which Pachycereus would be grown. If you do choose to cultivate a small specimen of Pachycereus pringlei in a container, repotting it can be helpful: if so, repot it as you would any other cactus, by removing it from the pot, cutting away any dead material from the roots, and replanting. Watch out for the plant's spines – they can really ruin your day. Grower's Tips These extraordinarily low-maintenance plants can basically grow untouched for decades, so there's really not a lot you need to worry about. Obviously it's very important that they receive adequate sun and heat, and be careful around their spines. If grown in containers, make sure that they're being repotted and that their soil isn't too moist. Other than that, these plants are about as simple and hands-off as it gets. https://worldofsucculents.com/how-to-grow-and-care-for-pachycereus/
Pachycereus marginatus, Mexican Fence Post
P. marginatus develops columnar trunks that grow slowly up to 3.5m tall. Stems are up to 10cm in diameter, with 5 to 7 ribs. Its central spine has 5-9 radials which are slightly yellowish in colour. Flowers are pink to green. Cacti occur in all shapes and sizes. They are extremely well adapted to drought and able to store water within the structure to ensure survival through dry periods. They can be found surviving in the driest places on the planet. Almost all cacti are succulents, and are often grown in greenhouses, particularly in regions unsuited to their cultivation outdoors. They can be grown in the ground or in suitable containers which means that they are suitable as houseplants, being tolerant of the often dry atmosphere. Potted cacti can be moved outside in the warm summer months. Synonyms: Cereus marginatus, Lemaireocereus marginatus
