Cacti are perennial succulent plants.

During the rainy season, water is held in the thick, hard-walled, succulent stem of a cactus. The leaves are photosynthetic, green, and meaty, while the stems are photosynthetic, green, and fleshy.

A thick, waxy layer keeps the water inside a cactus from evaporating. The roots of many cacti are lengthy and fibrous, absorbing moisture from the earth. Water may account for up to 90% of a cactus. The sticky material within a cactus may be used to purify water, removing heavy metals and microorganisms from polluted water.

Cacti have a wide range of stem forms. During the spring, summer, and fall months, cactus plants should be watered every 7-10 days for best growth. In the winter season, when the plant is resting or dormant, increase the time between watering sessions to approximately every four to six weeks.

What are the features of a cactus?

Cacti have thick, chlorophyll-containing stems that are either herbaceous or woody. Areoles, little cushion-like structures containing plant hairs and, in almost all species, spines or barbed bristles, differentiate cacti from other succulent plants. Areoles are modified branches that can produce flowers, other branches, and leaves if present.

Desert cactus plants store water and moisture in their plant cells to ensure that they have a water source during periods of acute drought. They are incredibly water-resistant, but symptoms of stress in the leaves, pods, or stems mean that one of these plants is suffering from a lack of hydration.

During lots of rainfall, an entirely grown saguaro cactus is capable of soaking up and holding up to 200 gal (757.08 l). Each cactus has its own water supply! Many desert explorers have discovered that a cactus can be cut open in an emergency to drink water.

Leaves are missing, considerably reduced, or transformed into spines in most species, reducing the amount of surface area from which water may be lost, and the stem has taken over the plant's photosynthetic tasks. Only the tropical vine genera Pereskia and Pereskopsis have traditional-looking functional leaves, but the Andean Maihuenia's leaves are rounded rather than flattened. The root systems are typically thin, fibrous, and shallow, with a broad range of thicknesses to absorb surface moisture.

From the buttonlike peyote (Lophophora) and low clusters of prickly pear cactus (Opuntia) and hedgehog cactus (Echinocereus) to the tall columns of barrel cacti (Ferocactus and Echinocactus) and the imposing saguaro, cacti vary widely in size and overall appearance (Carnegiea gigantea).

The majority of cacti grow on the ground, although certain tropical species, such as the leaf cactus (Epiphyllum), Rhipsalis, and Schlumbergera, are epiphytes, meaning they grow on other plants; some thrive on hard surfaces like rocks, and still, others climb up into trees.

Epiphytic plants have flattened stems that are slender and nearly leaflike. Whether the stem surface is smooth or decorated with projecting tubercles, ridges, or grooves, affects the plant's look.

How to eat cactus?

There are a surprising number of edible cactus. However, removing the spines may require some effort. Although all of the fruits of a real cactus appear to be safe to eat, several require specific preparation or even cooking.

Fruity, sweet, and bland flavors are all present, as are bitter and irritable flavors. Cactus range residents had to find out which plants were edible and which should be avoided.

For thousands of years, succulent plants like the agave have offered nourishment through their leaves. Not only do they provide essential moisture, but they may also be roasted for a number of uses. To fill up a healthy diet, the indigenous people blended various forms of plant-based food sources with hunting and gardening.

Although few cacti are a safe substitute for water, some have an unpleasant taste when drinking water from them. Harvesting any edible pieces would have been difficult and time-consuming, especially for such unappealing food sources.

Several, on the other hand, are well-known food stocks that are still in use today. There are several edible cacti to add to your landscaping in arid or warm climates. You might be able to find possibilities in the grocery stores of Latin America or even in specialty shops. Nopales, in particular, are widely available in both fresh and tinned forms. Many ethnic grocery stores sell prickly pear cactus 'tunas' (or fruits).

When harvesting nopales, the first step is to equip oneself. Long-sleeved shirts and thick gloves are recommended. Tongs and a sharp knife come in handy. Grasp the cactus pads with tongs and cut the portion where it connects to another pad. Using the tongs, remove the pad and place it in a bag.

Plastic bags are no match for the spines, so use a container or cotton bag instead. When you bring the pad home, wash it and scrape the spines off with the knife and tongs. If desired, remove the skin and eat it raw in salads, or sautéed, boiled, or roasted. You may also utilize the cactus pads medicinally, similar to how an aloe plant is used. Mosquitoes are said to be deterred by the sap in the cactus pads.

This incredible cactus has a wide range of applications, is easy to cultivate, and is an emblem of the American Southwest.

Eating cactus water or the plant itself is not recommended.

How to get water from it?

You may have heard that if you become lost and dehydrated in desert places, you can acquire water from cactus. A cactus, it turns out, is not a spine-covered bowl of fresh drinking water. Many cacti have cactus mucilage cells, which are thought to be adaptive because they help the cacti retain water.

In a dry environment with thirsty animals, such a plant would not endure long. Because water is such a valuable resource in the desert, most cactus species guard their spongy tissue with acidic and toxic alkaloids in addition to their threatening spines.

These compounds are often too acrid for most humans to take, as the ingested substance puts a strain on the kidneys. Some cactus species' meat can also cause vomiting, stomach upset, or temporary paralysis, none of which are good things to have in an emergency.

The prickly pear cactus and the fishhook barrel, a kind of barrel cactus, are notable exceptions to this rule (Ferocactus wislizeni). The production of calcium oxalate crystals by oxalic acid lowers calcium availability in the pads of the prickly pear cactus. The majority of the calcium in nopales was not accessible due to the high oxalic acid content. 

While both of these plants are unpleasant when eaten raw, they have lower concentrations of harmful compounds and may provide some moisture in a pinch. Cactus fruits are a preferable choice, but many are bitter when eaten raw.

The toxic Euphorbiaceae family member include cactus-like plants found in the deserts of southern Africa and Madagascar. If the milky sap of these plants gets into your eyes, it can burn your skin and mucous membranes and cause irreversible blindness.

The Fishhook Barrel Cactus is the only cactus that can provide drinking water if you ever find yourself on desert soil without even a drop of liquid substance. Keep in mind that it should only be used as a source of water in an emergency. Cactus is often not a safe option for portable water. Drinking cactus water on an empty stomach can result in stomach irritation, severe diarrhea, and vomiting, which can lead to further dehydration. However, if you're in a pinch, a few sips from the fishhook barrel cactus won't hurt. This is the only cactus from which it is safe to drink water. However, only small amounts should be consumed.

The fact is that a cactus plant is not a freshwater basin covered in spines. Acidic and toxic alkaloids, which may be highly dangerous, protect the cactus pulp portion. It's a toxic liquid water gel-like substance that's still dangerous to humans. Remember that your kidneys are weak when you are already weary and dehydrated. As a result, if you drink the beverage, your kidneys will have to work harder to break it down, perhaps putting you in danger.

Another major issue with drinking the fluid is that it causes extreme diarrhea, vomiting, and even temporary paralysis. In the midst of the desert, you don't want to experience any of these symptoms. However, this does not rule out the possibility of drinking cactus water entirely. A fishhook barrel cactus can be useful in severe conditions. Only a few people have reported ill effects from using this cactus as a source of emergency water.

Fun Facts About Cactus

The Greek word 'kaktos', which means 'cactus', is the source of the term 'cactus'. Kaktos is a Spanish artichoke that is also known in Greece as the 'prickly plant of Sicily.'

The word originates from the Latin word 'Cardoon' in a classical sense. According to Linnaeus, the modern-day American prickly cactus was linked to the cactal and called the plant cactus in 1769.

The Greeks called the prickly plant, which they related to an artichoke, a cactus. The plant they were mistaken for a cactus turned out to be an artichoke, and the two plants had unique characteristics. You may have heard that cacti are the plural form of the word cactus.

It seldom rains in the desert, as you may know. When it does rain, it is not heavy rainfall, and it might take a long time for the desert to see rain again. The desert sun is also scorching hot, and rainfall evaporates quickly. It is known that cacti have deep roots that allow them to absorb water from deep within the soil. In the searing desert heat, water evaporates fast. As a result, the soil never has the opportunity to absorb water and store it under the surface.

As a result, the plants have shallow root systems that allow them to absorb as much water as possible. Because the roots are only 0.5 in (1.3 cm) deep, rainwater reaches them quickly and is absorbed. The shallow roots are not only shallow, but they also traverse enormous regions. The roots may absorb more water at once by covering a larger surface area. The plant holds a lot of water in its stem after absorption, which makes it look bloated. The desert sand may appear dry because it drains quickly, but look at the turgidity of a cactus to see if it has recently rained.

Cactus conserves water in a variety of ways, including only opening its stomata at night. Cacti have acquired a notion known as crassulacean acid metabolism, according to experts (CAM). Plants with CAM can only open their stomata at night when the temperature is lower.

These plants store carbon dioxide at night and release it for food production during the day. The temperatures are unbearably high throughout the summer, which affects the vegetation. Cacti seal their stomata both day and night during this season, resulting in a dormant phase in which the plants do not develop at all. Nature aids the cactus' survival by removing its leaves.
