Commonly known as jade plant, friendship tree or Money Plant, Crassula ovata is a succulent plant with small pink or white flowers. Succulent plants, also known as succulents or fat plants, are Water -retaining Plants adapted to Arid climate or Soil conditions It is native to South Africa, and is common as a houseplant worldwide. The Republic of South Africa (also known by other official names) is a country located at the southern tip of the continent of Africa It is sometimes referred to as the money tree; however, the tree Pachira aquatica is the original "money tree. Pachira aquatica is a tropical wetland tree native to Central and South America where it grows in swamps "
Jades are evergeen plants with thick branches and smooth, rounded, fleshy leaves that grow in opposing pairs along the branches. Leaves are a rich jade green; some varieties may develop a red tinge on the edges of leaves when exposed to high levels of sunlight. New stem growth is the same color and texture as the leaves, but becomes brown and woody with age. Under the right conditions, they may produce small white or pink star like flowers in early spring.
The jade plant lends itself easily to the bonsai form and is popular as an indoor bonsai. Bonsai (盆栽 literally "potted plant" is the art of Aesthetic miniaturization of Trees by growing them in containers

Care
As succulents, they require a normal watering when the soil is dry in the summer, and very little watering in the winter. Succulent plants, also known as succulents or fat plants, are Water -retaining Plants adapted to Arid climate or Soil conditions Overwatering will cause them to lose their leaves (it is easy to identify overwatering by the characteristic crinkling look that the fallen leaves have) and eventually the stem will rot away. Though jades can survive overwatering, it is best to keep them on a 10 - 20 day cycle in the summer, and even less (up to a month dry) in the winter. Letting the soil dry between waterings is essential for a healthy jade. [1]
They will grow in full sun to light shade. However, they do not tolerate extreme heat or overexposure to direct sun very well, showing damage ranging from scorched leaves to loss of foliage and rotting stems. Most of the common species will tolerate a limited degree of frost but overexposure to cold weather will kill them.
The jade plant benefits from pruning, which should be done in the spring, before the growing season. Pruning a jade can be done over the period of a few weeks, and involves cutting stems back to a lateral branch. The purpose of pruning is twofold: for a top-heavy succulent like the jade, it is important that its trunk be able to support the weight of its leaves, and pruning encourages the trunk to grow in size; pruning also encourages root growth. Callouses should form on new cuts after a few days, and new growth should emerge from the stump within a few weeks of the cut.
Pests
Mealybugs are common pests to jades and can cause deformation to new growth. Mealybug is the common name of insects in Pseudococcidae, a family of unarmored Scale insects found in moist warm climates An infestation can be eliminated by killing each bug with a small cottonswab that has been dipped in rubbing alcohol. [2] It is important to repeat this process every day until all of the mealybugs have been killed, as new bugs may still be hatching even after the live bugs on the plant have been killed. [3]
Aphids are also common pests, though they tend to infest only the flower stalks. Red spider mites can also cause problems.
Be careful of using pesticides as Jades are very sensitive to them.
Soil
Jades grow best in well drained soil that does not have peat moss or other particles that will retain large amounts of water. Jade trees enjoy rocky hillsides and arid soil, so in cultivation many different soil mixes are used to mimic these favorable natural conditions. Some growers recommend 50/50 soil mixes of organic topsoil to perlite, haydite, turface, or small gravel and grit. Perlite is an Amorphous Volcanic Glass that has a relatively high Water content typically formed by the hydration of Obsidian Others have used coir, pine bark and river stones. The general consensus among growers is that the soil should drain quickly and be allowed to dry between waterings, so having a good amount of grit and gravel in the mix is essential.
Propagation
Jade trees are notoriously easy to propagate. They can be propagated by stem or leaf cuttings. Plant cutting, also known as striking/cloning is a technique for vegetatively (asexually propagating plants in whicha piece of the source plant containing at least one In the wild, stems and leaves will often break off and fall to the ground, and after a few weeks, they may grow roots and form a new plant.
In cultivation, new plants are made by cutting new growth (stems or leaves) and letting them dry. Roots will develop in or out of soil, though inserting the stem into moist soil will increase rooting speed.
