An additional crucial factor plays the environment such as sun, semi shade and level of humidity. The combination of these three crucial factors will determine the development of your bonsai. At the beginning it's difficult to determine the progress observing by naked eye but the end result will definitely make a difference.

Place the planted bonsai tree in an area that receives direct sunlight for at least four hours each day. Experts at bonsaigardener.org estimate that bonsai thrives fastest and healthiest when it is kept at a temperature at or higher than 60 degrees Fahrenheit during the daylight hours.
Water the bonsai tree every day, until the soil is most to the touch. Bonsai trees grow fastest in soil that is kept moist at all times.
Fertilize the bonsai plant every three weeks during the growing season, from early spring to later fall. Follow product instructions regarding dilution; be sure to dilute the fertilizer properly based on the size of the potting plant you used or else you risk burning the bonsai's roots with too much fertilizer.
Re-pot your bonsai plant every two years in the spring, before the growing cycle begins again. Use the same type of soil and planting pot as you did before, so that the bonsai is used to its surroundings. When replanting, trim at least a third of the roots from the end to make sure they are not crushed in the pot and are healthy to absorb nutrients. Depending on the size of the roots, you may need to trim more to fit it into the pot.
Check your bonsai tree at each watering for signs of pest infestations. Because of the constant watering the plant needs, it easily attracts insects. Treat any signs of infestation with a small dose of pesticide.
Cotoneaster and ligustrum. Given some good growing conditions, these should be ready for a nice "mame" style in a year from planting a cutting. I planted a couple of hundreds of ligustrum and a few of cotoneaster cuttings last year (everything rooted because when 5 % of the first setup died before they rooted, I instantly had replaced those with new cuttings and they rooted too), and I'm amazed with their growing rate.
When a seedling sprouts, there is usually just a single growing tip. As long as that tip is growing well, no other tips develop until the plant is taller. Bonsai requires trees that have low branches and the standard method is to do a very early pinch to remove the primary growth tip to force new growth points.
This is drastic for plants and many die. But without this step, plants do not develop character. You can improve the success rate with very healthy vigorously growing plants. Grow a lot of plants, grow them in the best possible environments, then prune drastically for outstanding results!
