How to make bonsai soil 

How to make bonsai soil:
In this video I have discussed about how to make bonsai soil at home.I have two recipes of bonsai soil - one with perlite and other without perlite.I have used broken brick chips,perlite,coco peat,sand,gravel etc.I have also discussed about alternatives of each and every ingredents. In this video I discuss the materials used to make bonsai soil mixes, and review the benefits of each of them. Lava rock, turface, fafard, red bonsai mix, basic bonsai mix also can be used. All bonsai soils are available on internet but making them at home is a great fun.In this video we are showing how we make or prepare our bonsai soil as previously requested by a viewer. Our bonsai soil is just sand from the river sieved to two sizes the coarser ones as drainage layer while the finer ones are made as middle and top layer. The middle and top layer are sometimes mix with organic fertilizers. Sometimes we use broken clay pots added to our drainage layer for moisture retaining property.
Bonsai (盆栽, "tray planting" About this sound pronunciation (help·info))[1] is a Japanese art form using trees grown in containers. Similar practices exist in other cultures, including the Chinese tradition of penzai or penjing from which the art originated, and the miniature living landscapes of Vietnamese hòn non bộ. The Japanese tradition dates back over a thousand years.
"Bonsai" is a Japanese pronunciation of the earlier Chinese term penzai. The word bonsai is often used in English as an umbrella term for all miniature trees in containers or pots.
The purposes of bonsai are primarily contemplation for the viewer, and the pleasant exercise of effort and ingenuity for the grower.[By contrast with other plant cultivation practices, bonsai is not intended for production of food or for medicine. Instead, bonsai practice focuses on long-term cultivation and shaping of one or more small trees growing in a container.
A bonsai is created beginning with a specimen of source material. This may be a cutting, seedling, or small tree of a species suitable for bonsai development. Bonsai can be created from nearly any perennial woody-stemmed tree or shrub species[3] that produces true branches and can be cultivated to remain small through pot confinement with crown and root pruning. Some species are popular as bonsai material because they have characteristics, such as small leaves or needles, that make them appropriate for the compact visual scope of bonsai.
Potting soil, also known as potting mix or potting compost, is a medium in which to grow plants, herbs and vegetables in a pot or other durable container. The first recorded use of the term is from an 1861 issue of the American Agriculturist.
Some common ingredients used in potting soil are peat, composted bark, sand, perlite and recycled mushroom compost, although many others are used and the proportions vary hugely. Most commercially available brands have their pH fine-tuned with ground limestone; some contain small amounts of fertilizer and slow-release nutrients. Despite its name, little or no soil is used in potting soil because it is considered too heavy for growing houseplants.check en.wikipedia.o... for more.
Some plants require potting soil that is specific for their environment. For example, an African violet would grow better in potting soil containing extra peat moss, while a cactus requires sharp (i.e. plenty of) drainage, most commonly perlite or sand.But potting soil is not ideal for all contained gardening. Insectivorous plants, such as the Venus flytrap and the pitcher plant, prefer nutrient-poor soils common to bogs and fens, while water-based plants thrive in a heavier topsoil mix.
Commercially available potting soil is sterilized, in order to avoid the spread of weeds and plant-borne diseases. It is possible to reuse commercial potting soil, provided that the remnants of plant roots, fungus, weeds and insects are removed from the mixture through heating before new planting can take place. Packaged potting soil is sold in bags ranging from 5 to 50 pounds (2.3-22.7 kg).
As with garden soil, potting soil can attract insects. For example, the fungus gnat is often found around houseplants because it lays eggs in moist potting soil.
Infections due to potting mix have been reported in Australia,[New Zealand,[11] the Netherlands[12] and the United States.
On June 13, 2000, the U.S. Centers for Disease Control and Prevention (CDC) reported that a woman in Washington was hospitalized with pneumonia that was triggered by Legionella longbeachae, the bacterium associated with Legionnaires' Disease. The CDC also confirmed the presence of Legionella longbeachae in soil in Australia and Japan.
