Cactus Gardening
All cactus plants are succulents, but not all succulents are cactus plants. Being able to tell the difference is one of the concerns in the cactus gardening section. Other questions to be asked and answered include the specifics of a cactus plant's adaptability, environmental impact, growing conditions, harmful stresses, native habitats, propagation methods, and value for people and wildlife.

What is the phylum of cactus plants?
The term that's synonymous with phylum, in the plant world, is division. So the phylum, or preferentially the division, of cactus plants is Magnoliophyta. It's the division for angiosperms, which also are called flowering plants. Flowering plants may develop from an embryo that has one or two leaves. A cactus is a dicotyledon, because it has two embryonic leaves.
Does a saguaro cactus have flowers or fruits?
same as other plants
The only difference is they store what they need
(like a balloon) for times when there is no food or water....their leaves have evovled into spines for protection and use their skin for sunlight collection as opposed to most plants that use their leaves for collection of heat and light...both collect water by root systems
What is the advantage of a swollen stem in a cactus?
its a place to store water for later use. succulent plants can lose 60% of their volume in draughts and still live to see the rain fall
A cactus plant doesn't move, because it's anchored in the soil by many fibrous, shallow roots underground. But it may spread above ground by its jointed parts breaking off and rooting in the ground around the cactus stem. In fact, one plant can root outward in such a way as to end up forming a dense, treelike, vegetative growth over quite an area of ground.
How does the prickly pear cactus reproduce?
The hedgehog cactus [Echinocereus spp] reproduces naturally by fleshy seeds. The seeds are found in its green to purple berries. They quickly are spread by the fruit's predators, such as birds and rodents. Additionally, the hedgehog cactus may reproduce by having its babies, or offsets, clumped or divided.
Why do cactus plants turn brown?
A cactus plant may turn brown, because of natural aging. Not all cactus plants are green in color, or stay that color in the course of a lifetime. Or a cactus plant may turn brown, because of environmental stress or stressors. One example of stress related browning is scorching from too much direct sunlight at too high temperatures. Other examples include viral, fungal or bacterial diseases; and pest attacks by predatory bugs and insects. Or a cactus plant may turn brown, because of drought. Way too little water dries out the fleshy tissues on the inside of the cactus. Or it may turn brown, because of death.
How tall are 15-year-old saguaro cactus plants?
Common opinion is that a saguaro grows about an inch to an inch and a half a year, give or take depending on the weather. But there is tremendous variation between individual specimens. One saguaro that is 150 years old might be roughly 150" tall, or about 12 feet while another in a more sunny position or with access to more water might reach 40 feet.
What is the adaptations of the fishhook cactus?
It is most commonly found in the Sonora Desert and parts of the Chihuahuan Desert.
Where do cactus flowers originate from?
Since the cactus is a plant, it does flower. The fruits that are produced after the cacti flowers contains seeds. Seeds are usually dispersed by birds who consume the fruit.
Is the cactus an unusual plant?
Yes, the cactus is an unusual plant. It tends to be grouped into two broad categories that are based on the biome in which it's found. One group is that of the desert cactus. This group is unusual for its successful survival in the harsh, extreme environment of strong sunlight and little moisture. The other group is that of the jungle cactus. This group is unusual for its successful survival in the enervating environment of much moisture and little direct sunlight.
What are the types of plant for cactus plant?
There are many different kinds of cactus plants.
For example, one stereotypical image of a cactus is of a plant that grows at ground level. In fact, some cactus plants grow high up in trees. Such cacti are called "epiphytic" because they grow "in the air" well above ground. For example, the epiphytic rat's tail (Aporocactusspp), orchid (Epiphyllum spp) and wickerwork (Selenicereus spp) cactus plants have airy roots that prefer to grow without soil.
Another stereotypical image of a cactus is of a smaller version of the giant saguaro cactus (Carnegiea gigantea), which grows into a towering 40 foot/12 meter column with branching arms. But that distinct profile is not the only shape that a cactus plant can assume. Some examples of different cactus shapes are the following:
1. The living rock or fossil cactus (Ariocarpus spp) takes on a rosette form. Most often, it is found growing underground.
2. The torch cactus (Cleistocactus spp) grows many ground-hugging, branching arms. The prickly pear cactus (Opuntia spp) also sports branching arms that look like fleshy pads.
3. The spineless Astrophytum is an example of one of the rotund types of cactus plants. Another example is the barrel cactus (Ferocactus spp), which looks exactly the way in which it is described. The chin or spider (Gymnocalycium spp) and pincushion (Mammillaria spp) cactus plants are shaped like globes. The globe-like Turk's cap cactus (Melocactus spp) has a densely spined crown that must be seen to be believed.
4. The Barbados gooseberry or rose cactus (Pereskia spp) grows as a bush, climber or tree.
Some other surprises in the cactus plant world are the beehive (Coryphantha spp) and agave (Leuchtenbergia principis) cactus plants. Both plants lack the stereotypically spreading, shallow, fibrous roots that are the hallmark of cactus plants. Instead, agave and beehive cactus plants have roots that look like some of our tuberous vegetables.
Still another surprise is the yellow peanut cactus (Echinopsis chamaecereus f. lutea). This cactus always has a color that falls within the yellow range of the spectrum. The reason lies in the plant's lack of chlorophyll. In fact, it has to be grafted onto a green cactus in order to get energizing photosynthetic products that green plants take for granted.
they dig deep down to the part were it can find water.
A cactus can be found in its native habitat, in the Americas. It can be found in private, public and research collections. For example, it can be found in the displays of botanical gardens and in the laboratories of educational institutions. It can be found among the sale items of mail order and online businesses, nurseries, and plant stores. And it can be found in the yards, work places, and houses of residential gardeners.
The prickly pear cactus genus [Opuntia spp] numbers over 360 species. There's no such thing as a uniform description for or look to the genus' members. For example, their common names may range from prickly pear, to Indian fig, to cholla, to bunny ears. Their heights may range from a couple of inches or centimeters to nearly 20 feet/6 meters tall. Their shapes may resemble a series of fleshy pads that look like badminton rackets, as in the case of Opuntia lindheimeri. Or they may have branching stems, as is the case with Opuntia tunicata. Their weapons against predators may take the form of barbed spines, or bristled tufts.
But what they all share is their love for the sun's heat and light, their comfort as the dominant vegetation of their niches, and their aversionto overwatering or waterlogging. Additionally, they share a budding into vivid spring, summer and fall flowers. They also share an appearance after blossoming of green, purple or red fruits. The fruits have seeds, but they may or may not have edible or flavorful tastes.
Why is cactus hill called cactus hill?
From the Latin 'cactus' taken from the name 'cardoon' which is a type of prickly plant from Sicily (the Spanish Artichoke) Also from the Greek name Kaktos
What are treatments for cactus rash?
the Bayer herbicide is a good solution for most of the plant rashes therefore it is likely to work for the cactus rash too.
How do cactus plants adapt to their habitats?
Cactus plants adapt to their extreme habitats by specializing body parts and functions. For example, the roots concentrate on anchoring the plant and on capturing nutrients and water from the soil. The stem concentrates on processing and storing water, nutrient solutions, and energizing starches and sugars. It also concentrates on controlling breathing, gas exchanges, and water loss through its pores, or stomata. It concentrates too on the photosynthetic interaction with sunlight. And the modified leavesconcentrate on directing moisture down to the ground, to be taken in by the cactus' roots.
They have prickles to protect themselves.
How many arms can a saguaro have?
Sometime it can take several years. A minumum height of 5ft to 6 ft most will sproat an arm. One way to produce side growth in a short 2-3 months is to top cut the main stem then lateral growth with bu pushed.

Why does not cactus survive in north?
no,a cactus can't survive in northpole because it will become frozen and it would die. Cactus can almostly survive in any climate. In northpole it is very cold and the cactus is not adapted to low temperatures. Cactus need warmth and in northpole there is freezing weather and freezing water, cactus can't survive in northpole.
Describe miliaria rubra type of prickly heat?
Is the most superficial of the occlusions. Only the thin upper layer of skin is affected. Little blisters of sweat that cannot escape to the surface form. Looks like a bad sunburn as it just starts to blister.
Can cacti survive in the tropics?
Cacti can live in the tropics, but they will probably die from too much water. Cacti retain water so if there is too much water, they basically drown. Tropics tend to have clay soil, and cacti need sand because of the way their roots grow and how the sand in the deserts retain the water, and clay might affect the cacti.
