Containers

• Bonsai trees grow in flat, shallow pots. The shallowness of the container restricts how much the roots grown. Bonsai trees are prone to root rot, so it is important to grow bonsai trees in containers with several drainage holes.
  
  

Water

• Bonsai trees require regular watering, but it is important to allow the soil to dry out before watering. The best way to water a bonsai tree is to place it in a sink or tub of water, with enough water to cover the top of the soil. After soaking for approximately 15 minutes, the tree can be removed and allowed to drain thoroughly.
  
  

Pruning

• Pruning helps shape bonsai trees and forms them into works of art. It also helps to maintain the health of the tree. The dormant season is the ideal time for trimming bonsai trees. Pine trees stop growing in the fall, and deciduous trees are best trimmed early spring.
  
  

Sunlight

• Bonsai trees grown indoors do best if placed in a sunny window. Rotating regularly allows all sides of the tree to receive equal amounts of light.
