    Bonsai Basic Facts
  • Bonsai are not dwarf versions or genetically different from a regular plant.
  • Bonsai should last the normal lifespan of the plant species, and possibly twice as long.
  • Almost any long-lived plant can be trained to become bonsai.
  • Bonsai are not houseplants. They need to be outdoors, with special protection in winter.
  • Bonsai are traditionally displayed on wooden benches. They have a front and back and are always shown from the front.
  • While most bonsai rarely exceed 3 feet in height, the Imperial Size grows up to 4 feet. Only the Japanese Emperor can have bonsai larger than 4 feet.

    Bonsai Caring Techniques
  • Correct pruning is the chief technique, which separates bonsai from a houseplant.
  • Wiring is used to shape plants into the desired form.

How to Bring Home a Bonsai Bonsai experts and professionals at the Chicago Botanic Garden suggest the following tips for selecting and caring for bonsai at home.

    Selecting Tips:
  • Leaf color should be even, with no blotches or blemishes.
  • There should be no scars on the tree's trunk or branches from pruning or wiring.
  • The tree's trunk should be strong and even tapered.
  • Surface roots should fan out naturally from the trunk's base.
  • Roots intended to clasp a rock or piece of wood should truly adhere.
  • Branches should be well proportioned and evenly spaced.
  • The plant's pot or container will be in proportion to the tree, and of complementary nature.
  • Bonsai should be placed in a container in a way that creates visual balance, slightly raised so the plant can be viewed at eye level.
  • Flowers, fruit, leaves should be in proportion to each other and the plant overall.
  • Decorative stone, moss or other surface covering should be natural and in scale to the plant.

    Caring Tips:
  • Tropical bonsai plants must be protected in winter. Hardy bonsai can remain outside.
  • Turn bonsai frequently so plants receive light equally on all sides.
  • Water plants only when the soil surface feels dry to the touch. Then, water the entire root ball until it is moist.
  • Regularly apply a half-strength organic or non-organic 20-20-20 fertilizer. Full-strength fertilizers can burn tender roots.
  • Treatment for insects and diseases vary, depending on season and type of plant.
