Correct Location For Bonsai: Bonsai grow best when given exposure to good air circulation, and at least five hours of sun per day. The trees will benefit from occasional turning to expose all sides to sunlight, as this will aid in an even growth distribution. On occasion, bonsai may be brought indoors for  display. They can be kept inside for about one week at a time but constant vigilance on their water requirements is necessary. They must never dry out.

Transplanting: Every so often, bonsai need to be taken out of their containers, and have their roots trimmed. This is important so that roots don't become overcrowded in their confined environment and also roots will be rejuvenated when cut so that many smaller feeder roots are established.
For young trees, every 2 or 3 years is about right. For established and older bonsai every 4 or 5 years is sufficient. Early spring is the best time to perform this procedure, from late March to mid April. In colder climates, such as Northern Japan and Hokkaido, one month later is recommended. 

Soil: Pines prefer course soil, and for this reason mountain granite is mainly used. In the Kanto-Tokai Region, a mixture of granite and 30 % Akadama clay is used, while the seaside regions of Japan and the Tohoku- Hokkaido area prefer granite only. When potting up bonsai, 4-8 mm of gravel should be placed at the of the to promote drainage, and the main soil should be 80 % granite soil. A top dressing consisting of fine granite Akadama, and Fuji ( volcanic soil ) should be used as final touch. While bonsai are in training course soil is recommended. And as the trees become established, the soil mixture can be finer.

Watering and Fertilizer: During hot summer weather drying conditions may necessitate the need for watering every day, sometimes even twice a day. The routine cooler spring-autumm conditions usually require a schedule of watering every other day, while winter time may require the bonsai ti need water every third day. At all times of the year however, when watering, make sure it is through, and that water percolates completely through the Pot and out the drainage holes.
All bonsai require some degree of fertilization to replenish their need for minerals which are constantly leeched out due to daily watering. Several rape seed balls can be placed on the top of the soil in the pot during the growing months between March and October. When bonsai have just been replanted, it is best to wait 3-4 weeks for new to acclimate themselves.
 

Insect and Disease Control: Pines are generally strong, tolerant trees impervious to most pest and diseases. But there are certain preventive measures that can help insure the health of bonsai. Fumigate for red spider mite with FW-293 and Comite during their active feeding cycle July through September, and during winter, a concentrated spray of lime sulphur 20-30 times the recommended rate will usually eliminate the occurance of this pest. For sucking insects such as, Aplios Oxydeprofos, and Ekatin insecticides applied during their peak feeding season ( usually summer ) will be effective. Sometimes pines are susceptible to certain diseases, and an application af a fungicide like Zineb 75 wp during summer and early autumn will be an effective control. A winter application of lime sulphur will usually be adequate protection for insects and disease at this time. At various times you may want to mix both insecticides and fungicides together for a broad spectrum control. At all times check for their compatibility, and above all, always read the labels of all pesticides, and follow manufacturers recommendations.

Seishi and Styling: The pinching of spring buds is done on established bonsai or spring planted Bonsai from the mid to end of June. For younger trees, bud pinching is performed from the end of june, to the middle of july, When pinching buds, a little bit of the original candle is left, and by this treatment a second set of buds will form increasing foliage density.
During the months from November to January, the removal of old needles is suggested to enhance the formation of new buds. this is also an ideal time to prune unnecessary or dead branches, and apply wire for branch placement to maintain the shape and style of bonsai.
