light
Most bonsai prefer bright, direct light; 3 or more hours depending on the variety.
soil
Use a Bonsai specific potting mix which includes calcined clay, expanded shale, and compost. When you notice the soil is not able to hold water, it is time to repot and prune roots. Some varieties need to be repotted every 2-3 years; others can go as long as 5 years.
water
Water completely allowing the soil to become saturated. Never allow soil to dry out all the way.
fertilizer
Tropical and subtropical: Fertilize weekly during the growing season, then monthy during fall and winter months.
Deciduous: Fertilize weekly during the growing season. When leaves fall, fertilization should stop as the tree has gone dormant.
Conifers: Fertilize weekly during the growing season, then monthy during fall and winter months.
