Plant the Mexican fencepost in full sun with reflected heat or light shade, in well-draining soil. Although it can withstand drought, it prefers the occasional water during the hot, dry months. Between irrigations, let the soil to totally dry out. It can withstand temperatures up to roughly 25 degrees Fahrenheit. Styrofoam cups should be placed on the cactus’ tips to protect them when the temperature falls below the low 20s.
What is the rate of growth of Mexican fence post cactus?
The equivalent of “thin jeans” in the cactus world are Mexican fence posts. No other huge cactus has this much flesh showing. This common moniker doesn’t give one of the most significant and dependable huge cacti for premium appearance and contemporary design credit.
Maybe you’ve been scrolling through Pinterest and current publications looking at pictures of the ethnobotanical garden in Oaxaca City that have been posted online. Fence post cactus linear plantings have finally reached their pinnacle and are now the favorites of the unnatural planting crowd. Many years ago, I went to the same Oaxacan garden right after it had been established, and I still have pictures of the original flowers on the grounds of a former convent from the Spanish colonial era. Since then, I’ve been mesmerized by the rural cactus fences made by lining up solitary stems of this species in a solid line to form a mass. These are incredibly simple to maintain with drip irrigation and can make beautiful screens because mature plants can grow to be 12 feet tall.
This thin cactus was the first one I ever seen at Moorten Botanical Garden. Here, year after year, I noticed the large group near the pond with flowers and fruit. The few ribs that each had a staccato series of grey extrusions became something I also came to enjoy. They are safer and simpler to maneuver around because of their short spines. They also make one of the best cactus for small spaces or poolside.
One day, when we were trimming the clump of fence posts, Clark Moorten warned, “They’re brittle.” These long cuttings must be supported throughout their whole length to prevent breaking in two like a cucumber.
Moorten gathered a piece of carpet padding and began delicately wrapping each stem to protect the delicacy of all that lovely skin. Too frequently, a handling error can ruin a lovely specimen for life, and for this species, it matters greatly without a covering of spines to guard its delicate areas.
Moorten had previously wrapped towering cacti with scraps of old carpet, but this time the padding was much softer. It avoided the abrasions that long-distance transport of the stiff carpet strands might cause. We were able to carry the stems we took while wrapped up like carpet mummies without making a single stab. It’s also a fantastic technique to remove substantial chunks of any tall columnar cacti that need to be replanted but are hazardous, cumbersome, and frequently highly valuable as well.
Pachycereus marginatus, sometimes known as the fence post cactus, may be found throughout much of northern Mexico along the Border States. It can reportedly grow up to 3 feet tall throughout the summer due to its capacity to adapt to the Gulf of Mexico’s summer monsoon season. However, the plants can be found in extremely dry regions where they are thinner and develop at a much slower rate. This implies that they enjoy the summertime water because it is what they need to survive here in the desert.
The white, sweet edible flesh of the fence post fruit is surrounded by crunchy, black seeds. Since the next day they are nothing more than a hollow shell of spines and crimson skin, they are adored by all birds that appear to be able to predict when they ripen in the heat.
For the best appearance, give this cactus a protected yard and regular summer water. Blowing debris in the open can leave skin with unsightly scars. They become brown and yellow in areas from too much western sun, which is also a result of irrigation water scald.
Fence post cactus growing along the coast should be avoided since they will transform once they enter this desert environment. If planted right away, voids between the formerly densely planted fence may start to form due to an adaptive shrinking. The outcomes will be far more successful if they are harvested from nearby mother plants. However, if you want to go big, you can get some fantastic container examples from nearby growers in the valley, who can probably help you compile a linear work of living art.
A Mexican Fence Post Cactus needs how much water?
If you’re planting it outside, be sure there aren’t any big trees or other large objects nearby that could cast shade on the plant when the sun changes.
You won’t have to worry about this plant getting too much sun. Therefore, neither sunscreen nor filters are required.
Why not think about utilizing a grow light if your house is dark throughout the winter? LED or fluorescent lights can be used as grow lights. Because they consume less electricity and are environmentally benign, LEDs are growing in popularity.
Mexican Wall Post cactus lighting advice: Some grow lights are appealing lamps that may be fastened to the edge of a shelf. To ensure that your plant is not solely exposed to light from one side, remember to rotate it every few days.
Watering
Water is uncommon in deserts, as we all know, and the Mexican Fence Post Cactus can go for months without it if necessary. Having said that, you can water your houseplant during the summer. Water it once every two to four weeks. Between waterings, let the soil totally dry out.
Never water a plant after dark. At night, the temperature drops and the water in the soil gets even colder.
Don’t water your Lophocereus marginatus excessively. If the roots begin to rot in wet soil, your plant won’t be happy and can even pass away. Make sure the drainage holes at the bottom of your plant container are large enough and are not obstructed by sand. Water must flow out of the container and must not collect at the base.
For Mexican Fence outside Normal to low rainfall should be acceptable after the cactus grows. In a climate with frequent tropical downpours, this plant won’t thrive. If you have the space, think about growing it in a pot on a covered patio if you receive a lot of rain.
Mexican Wall Post-Cactus water care advice: Don’t worry if you have to leave your plant for a few weeks while you are on vacation. It is capable of enduring longer periods without water.
Temperature
Consider hot and dry. When feasible, the Mexican Fence Post Cactus seeks heat. It grows best in environments that are as hot as 80°F (21°C) or even higher.
It can withstand temperatures as low as 25F (-3C) for relatively brief periods of time. Keep your Mexican Fence Post Cactus out of the frost; doing so could cause damage or even death.
Can Mexican Fence Post Cactus be cut?
This is a tale of two fresh starts—one for my second-oldest daughter, Rachele, and one for a new cactus.
Mexican Fence Post (Pachycereus marinatus), the cactus pictured above, has been contentedly flourishing in my front garden.
What may not be immediately clear is that I started this cactus 11 years ago from a 2-foot piece (referred to as a “cutting”) that a client gave me from their big Mexican Fence Post cactus.
Compare the image above with the first one by paying close attention to it. Do you see where we chopped the cactus in half?
Our neighbors wanted a cactus like ours because they had recently redone the landscaping in their front yard. They were aware that they would need to begin with a much smaller one, of course, but they had no idea how much it would cost to purchase one at the nursery.
We decided to give them a piece (cutting) off of our Mexican fence post because our cactus had been flourishing so well. So, my daughter, husband, and I gathered to cut a piece of our cactus.
My spouse took a pruning saw and began slicing off the bottom of a good-sized piece of cactus while I held onto it.
To grasp onto cacti with short thorns, it’s helpful to use many layers of newspaper and gloves. You can use carpet remnants for cacti with larger thorns. Be ready since a piece of sliced cactus will weigh considerably more than you anticipate.
My husband and daughter used our wheelbarrow to transport the cactus trimming to our neighbor’s home.
In order to prevent the cut site from rotting when the cacti are replanted, we next left the cutting in a dry, shaded location for two weeks.
My daughter Rachele left for basic training in the Navy exactly 3 days after helping us with the cactus cutting. For us, it was a difficult goodbye, but for her, it was a fresh start.
The fresh cactus was placed in its new location with a wooden post for support after two weeks had passed.
The cut end was not watered for the first month following planting to ensure that it had callused over completely.
The cactus was watered thoroughly once a month until November following planting.
*Every time I glanced at the newly planted cactus, I thought about my daughter and how she was adjusting to life in the Navy.
The new cutting is thriving so well a year later that two additional parts have even sprouted.
While I may not be as close to my daughter as these two cacti are, she is growing and succeeding in her new job with the Navy, much like the new cactus. We’re extremely pleased with her!
The Mexican fence post cactus I have is turning yellow. Why?
Reduced watering may be able to stop this Mexican fence post cactus’ browning. The falling of flowers is typical for tomatoes and many other plants since they produce more blooms than fruit.
Cacti found on Mexican fence posts bloom?
This attractive cactus grows to a height of twenty feet or more and has towering, columnar trunks. A pipe organ-like formation of thick, cylindrical stem clusters is produced. The plant grows many arms during the course of its lifetime, and additional irrigation speeds up growth. It has ribs that are a dark green color and little spines. Its smooth stems include five to seven ribs and a yellowish central spine. The plant’s common name comes from the fact that it is frequently utilized to build a living fence, mostly beside roads, in many Mexican communities and towns. The cactus produces spectacular tubular pinkish-red flowers in the spring. It produces spiky, yellowish to red fruit with black seeds after the blooming cycle. Plant it against a tall wall, as a vertical accent, as a desert accent, or use cuttings of this plant to make a living fence. Additionally useful in arid or tropical environments, it requires little care. The Mexican fence post is widely planted and has become naturalized throughout Mexico. It is native to the states of Hidalgo, Queretaro, and Guanajuato.
What’s causing my red cactus to become black?
There are many different colors for cacti, but black shouldn’t be one of them. If you’ve discovered that some of your cactus, or possibly the entire plant, has turned black, this is obviously not ideal. What can you now do to help your cactus?
What causes cactus to turn black, and what remedies are there? Fungal infections, such as bacterial necrosis, crown rot, and phyllosticta pad spotting, cause cacti to turn black. At this point, removing the afflicted regions and attempting to stop the infection from spreading to the remainder of your cactus and other neighboring indoor plants are the only ways to rescue your indoor plant.
Are the fruits of Mexican fence post cacti edible?
As its name implies, the Mexican Fencepost is frequently employed as a fence or barrier. From March through April, they can grow greenish-pink blooms. Fruits made from these blooms are tasty, dark-red, and edible. What maintenance should I provide my Mexican fencepost?
Mexican fence posts grow to what heights?
Mexican Wall Post has pink, white, yellow, and light green flowers that blossom in the spring. When fully grown, the height is normally around 20 feet.
Can I cut my cactus’ top off?
The enjoyable part is now. With the exception of damaged or dead stems and leaves, almost all of the material you remove is salvageable.
- If pads are placed on top of soil, they will take root and grow into a new plant of the same species.
- After several days, cut stems and trunks should be allowed to callus before being planted to grow new cacti.
- You should immediately pot up any offsets or pups that you remove from the specimen’s base because they are new plants in their own right.
- Compost is used for dead flower stalks and leaves, although certain cactus species develop leaves on the flower stem that can be treated similarly to other species’ pad material. Within a month, the majority of cactus portions will begin to root.
Once you’ve brought your first cactus back to life, you’ll enjoy creating more of the magnificent plant so you can add to your collection or give them as gifts to loved ones.
How should a blue torch cactus be cared for?
Loose, well-draining, and somewhat fertile soil. Mixtures of cactus or succulent soil work well.
Temperature: Capable of withstanding temperatures as low as 35 degrees for a short duration.
Water: The Blue Torch Cactus is not sensitive to humidity like other cacti are. regular irrigation during the summer’s heat (slightly more than the average cactus). When it’s dormant throughout the cool winter months, sometimes water the plant. In between waterings, make sure the soil is fully dry.
In the winter, when the Mexican Fence Post is dormant, very little water is needed. During the growing season in the summer, more water is used.
Can you keep a cactus from going bad?
A cactus going yellow can be a sign of too much light, the improper soil, or a pot that is too tiny. Don’t be alarmed if it turns yellowish; you can probably bring it back to life. You’re either underwatering or overwatering, most likely.
It’s possible that you’re drowning your plant by committing a common cacti watering blunder. You may simply fix this by altering your watering schedule. When a yellow tint starts to appear on your cactus, we consulted a houseplant specialist for advice.
Leaf Envy (opens in new tab), a retailer of indoor plants and cactus, is owned and operated by Beth Chapman. She has extensive knowledge in this subject and claims that while there isn’t a universal solution, there are a few common aspects relating to its habitat and conditions.
She advises us to start by understanding where our cacti are placed in the house. Cacti, in contrast to most plants, benefit from a lot of bright, direct sunlight.
“Not getting enough light exposure could affect its health and induce discoloration,” says Beth. Second, cactus don’t require as much watering as the rest of your plant collection because they can withstand desert heat and drought-like circumstances.
Beth advises to water plants only after the earth has become completely dry and to generally water plants less during the winter. She advises not watering your cactus if you’ve overwatered it until the soil has dried out and checking to see whether the roots have died.
If they haven’t passed away, you’re in luck, and we recommend repotting your plant using soil made specifically for cacti, says Beth. However, gloves are advised because the terrain can be somewhat thorny.
