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 a cactus characteristics?
There are several physical characteristics to a cactus. First off, they are shades of green. the reason why i say shades, is because not every one cactus is going to be the same color or green, some may look more brown. Another characteristic is it can get to be really tall. Some are shorter but still, if you look at some of the ones in deserts, you will see how big they really are. Lastly, they have thorns on them. These thorns are obviously very sharp and will hurt you if you touch them. hope this helped! remember, do not copy this word for word, rearrange the order of things and use different wording styles. Teachers have ways of finding out you cheated. Don't learn it the hard way. Its not that hard to write things in your own words. Its better to rearrange things and make it so it sounds like you, than to get a zero on your assignment.
Yes, cactus plants can be brown. For example, the living rock or fossil cactus [Ariocarpus spp] is gray brown in color. It isn't the only cactus that isn't green. In the way of another example, the yellow peanut cactus [Echinopsis chamaecereus f. lutea] lacks greenness of color, because it lacks chlorophyll. It has to be grafted onto a green cactus to be able to supply itself with energizing photosynthetic products.
Yes, cactus plants have roots.
Specifically, a cactus plant needs roots to take in moisture and dissolved nutrients from the soil. It is upon this underground supply of moisture and dissolved nutrients that the entire plant depends for survival and growth. Additionally, roots keep the plant anchored in the ground or - in the case of epiphytic cactus plants - to the branches of trees.
What is the harmful effect of cactus plant?
Cacti are considered types of succulents (all of which fall under the broad category of "plant"), and are often regarded as harmful because of their spines. Many cacti have sharp spines or hooks that stick out from their surface and serve as protection against other animals. These spines can be very sharp and may pierce the skin if hit. Some cacti like Opuntia have small fuzzy spines that seem harmless but when brushed up against or put into contact with human skin may string and look/feel like many tiny splinters. Like thorns, cactus spines have the potential to draw blood and scrape, pierce or cut and therefore may be considered harmful.
What happens when you fall in a cactus and spikes go in your hand?
Scream "ouch!", shake your hand, probably utter a few profanities and then wash the wound and cover it with a band-aid. Don't forget to use tweezers to remove any spines stuck in your hand.
Then decide how to get revenge on your older siblings who told you to do it, insisting that it's all soft and fluffy and wouldn't hurt at all.
What environmental pressure does a cactus has?
Cacti occasionally suffer from the pressures of drought and other animals. Birds and mammals try to get the water from the cacti so THEY can survive. This is why cacti have thorns.
What stops the cactus blowing away in the wind?
deepinto the Earth searching for water. Since they go so far, they must be very strong. The stronger the roots, the deeper they search for water. Roots secure plants to the ground, but some can't.
Do saguaro cactus plants grow in sandy conditions?
A saguaro would probably quickly get root rot and die as the soil in Florida is much too moist for a saguaro to remain healthy. They need a fast draining soil that does not remain wet for long after a rain.
Why would a cactus shrink in the middle?
When water is available, cacti absorb more than they need for the present use. Their tissues, particularly in the thick body or trunk of the cacti, and in the thick pads of the Prickly Pear, swell up like sponges. When the weather dries and no water is available through their roots, cacti use this stored water. Their tissues then shrink up as the moisture is used, and the stem and/or pads become noticably smaller and wrinkled.
How do you care for Christmas cactus plants?
You can care for a Christmas cactus by putting it in indirect sunlight, keep it humid, check the moisture in the soil for the need to water and use fertilizer. Giving the plant the proper light will allow it to bloom at just the right time for the holiday.
Does barrel cactus have a verry deep roots?
The barrel cactus [Echinocactus and Ferocactusspp] has spreading, shallow, fibrous roots. It's the only kind of roots that a cactus plant has. The roots need to spread out in search of rare soil moisture. They also need to be shallow to catch the drops of dew, fog, or rain that drip to the ground and into the soil. They need to be fibrous, too, to take in water and dissolved nutrients, to send up the stem for the photosynthetic interaction with sunlight.
The exact number of cactus species depends upon the particular source that's accepted as an authority. Figures may range from around 2,000+ to as high as 6,000. It nevertheless may be said with a certainty that the number ranges in the thousands.
What is the name of a spiny cactus?
Acantha is the proper name for the cactus spike. It's from the Greek word 'akantha', to refer to a 'thorny' plant. The Greek word in turn traces back to ancient Greek mythology. It's the name of a nymph who scratched the Greek god Apollo's face. Apollo promptly turned her into an acanthus plant.
How did the organ-pipe cactus get its name?
The word cactus comes from kaktos, which his Greek for 'thistle'. The name was chosen by Carolus Linnaeus [May 23, 1707-January 10, 1778]. Linnaeus invented and published a universal system of botanical plants names in 1753, with his 'Species Plantarum'.
How tall can a saguaro cactus grow?
The height depends upon the type of cactus. There in fact is quite a range in possible cactus heights. For example, a cactus plant may be tall, such as the 40 foot/12 meter giant saguaro cactus [Carnegiea gigantea]. Or it may be small, such as the 2 inch/5 centimeter Ariocarpus fissuratus, which is one of the living rock or fossil cactus plants.
The tallest cactus is the cardon cactus (Pachycereus pringlei)of Mexico which grows to 63 feet or more in height.
17Wolf359 added: There are actually number of cactus taller and bigger that both C. gigantea and P. pringlei. The tallest reported cactus at over 80 feet is Pachycereus grandis. Pachycereus weberi, Backebergia militaris, Neobuxbaumia macrocephala, Trichcereus tersheckii and Neocardensia hertzogonia are all of similar size or larger than C. gigantea or P. pringlei.
Does the prickly pear cactus bloom once?
It depends upon the particular cactus. For example, the old man cactus [Cephalocereus senilis] reaches a mature height of 50 feet/15 meters. It may mature to an age of around 200 years. It's slow growing. So it doesn't flower the first 20 years of its existence.
How do you care for a aloe vera plant?
Aloe vera has been widely grown as an ornamental plant. The species is popular with modern gardeners as a putatively medicinal plant and due to its interesting flowers, form and succulence. This succulence enables the species to survive in areas of low natural rainfall, making it ideal for rockeries and other low-water use gardens.

What are two reasons for why cactus plants have spines?
They are present in hot deserts which are scarce in water so in order to reduce the loss of water by Transpiration from the surface of the leaves, its leaves are reduced to spines.This is a type of adaptation of the plant.
What does a cactus use to feed itself?
A cactus draws nutrients and water through the roots. Water is stored in special cells that swell when filled with water. The skin is covered in a waxy film to prevent loss of water by evaporation.
um well idrk but the sizes, the wheather it has milk or not.
Yes, cactus compost can be used to plant aloe vera. Botanists and horticulturalists describes aloe vera and cactus as succulents with similar bio-geographies and biological requirements. A cactus compost may be employed regardless of whether aloe vera serves as a house or outdoor plant.
