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 parts of the nettle plant are used for medicinal purposes?
The leaves and stems should be gathered from young plants on a dry day, before the plant flowers. Nettle's aerial parts may be used fresh or dried. The root is harvested in the fall when the plant has died back.
How tall is a saguaro cactus when its fifty years old?
The saguaro growth depends on the amount of rainfall it receives so they grow faster in some areas than in others. At 50 years the cactus would probably be in the 10 to 15 foot range and not have grown an arm yet.
How is a cactus adapted to its environment?
by dancing here and ther
It has shallow roots that are spread out so that it can receive as much water as it can after a rainfall. It has 'thorns' that prevent animals from eating it. It also has a waxy covering to prevent water loss.
What parts of the noni tree are used for medicinal purposes?
The noni fruit and other parts of the plant also are used medicinally, including the leaves, bark, flowers, and roots.
How do you grow flowers on cactus plants?
Flowers grow, because of the appropriate fit between a plant's genetic inheritance and its environment. Specifically, a flowering plant blooms in response to necessary levels of heat, light, and moisture in its environment. That's why a cactus tends to flower after a rare desert rain event.
But not all cactus plants flower. Those that are capable of flowering may refuse to do so under certain conditions. For example, a cactus plant tends to flower more in the wild than in cultivation. In cultivation, it tends to flower more in the ground than in containers. So it also tends to flower more outside than indoors. The preceding may hold true regardless of whether the pollination is natural or gardener made.
Can cactus plants grow in dirt?
Yes, desert cactus plants can grow in dirt. But no, jungle cactus plants aren't used to growing out of the ground. They grow with their roots exposed to the air. In the jungle, the problem is the reverse of the desert. It's a situation of high moisture levels and low light. So jungle cactus plants root high up on tree trunks and branches to get closer to the filtered sunlight of the thick, dense, dark tropical forests.
What is the ecological niche of the saguaro cactus?
The desert is the ecological niche of the saguaro cactus [Carnegiea gigantea]. Within that niche, the saguaro is a resident of lower elevations. Specifically, it prefers an elevation range of 600-3,600 feet/180-1,080 meters.
A cross between true-breeding sharp-spined cactus and a spineless cactus would produce?
All sharp-spined progeny.
How do mosquitoes affect ecosystems?
Mosquitoes are important in the ecosystems as they are an important food source for organisms such as tree frogs, lizards, snakes, fish, birds, bats and arthropods including dragonflies and Spiders. The mosquito larvae are also important food for fish and other predatory aquatic organisms.
Where can the saquaro cactus be found?
The saguaro cactus is a native to the Sonoran Desert of the southwestern United States and northwest Mexico. It is the largest cactus found in the United States.
What is the phenotype ratio for the cross of Ll cactus?
I don't know what trait is being measured here so I am going to pretend that it is height, where L is the tall allele and l is the short allele.
You get:
LL: 1/4
Ll: 1/2
ll: 1/4
This is the GENOTYPE ratio. Assuming L is dominant and l is recessive, the GENOTYPE ratio would be
Tall: 3/4
Short: 1/4
You can confirm this by making a Punnet square
No not true. Spines on plants are sharp needle like that protect the plants from any harm. I think cacti have spines
Is it appropriate to place cacti in a bathroom?
If the room gets plenty of light it is OK to grow cacti in it, also it depends on the species you are growing since some genera/species require more light than others to grow properly. If your cacti do not get enough light they will stretch for it and this looks really ugly, the technical term for this is etiolation.
What is the cactus' shelter in the desert?
Some species of cactus do best when they grow in the shade of a shrub or other leafy plant. That is the only 'shelter' they might have in the desert.
What kind of roots do all cactus plants have?
All cactus plants have fibrous, shallow roots. They need this kind of root in order to spread quickly and widely throughout the soil in search of moisture. They don't need thicker roots, because they don't have storage responsibilities within the cactus plant's division of labor. Instead, those responsibilities are carried out by the fleshy, thick stem.
How do the spines on a cactus help it survive?
Spines: Spines help the cactus in several ways. The most obvious use of the spines is for protection against foragers. The cactus basically states "How much pain are you willing to indure to get a drink in this desert?"; Surprisingly, some animals do partake. In some cactus varieties the spines participate in water collection. Water from dew condenses on spines and, in some cactus species, downward-pointing spines help to direct rainwater to the roots of the plant. Spines help to reflect light away from the cactus stem theoretically lowering the stem temperature. Some spines also trap in a layer of air next to the cactus stem preventing loss of water via evaporative cooling.
How do cholla cactus plants get water?
Cholla cactus plants [Cylindropuntia spp] mainly get water from the soil. Their shallow, fibrous roots spread out to find and take in any available moisture in the soil. That moisture may be in the soil because of dew that drips from the plant, onto the ground, and into the soil. Or it may be in the soil because of a rain or snow fall event.
