Bonsai Care

Bonsai For Ever — Basic Bonsai Care Guide

  1. What Does “Bonsai” Mean?

“Bonsai is art, is passion, and the name of the game is patience.”

The word bonsai (pronounced bone-sigh) literally means “tree in a shallow pot.” Today, it refers to miniature trees that are carefully cultivated and trained in containers of various shapes and sizes.

  1. Indoor or Outdoor?

Most bonsai are naturally outdoor trees. In traditional Japanese homes, bonsai are displayed indoors only for short periods and then returned outside.

Because bonsai grow in small containers, they are more sensitive to extreme heat and cold than trees planted in the ground. Providing proper protection during harsh weather is essential for their health.

Important: Tropical bonsai (such as Ficus, Fukien Tea, Brazilian Rain Tree, and similar varieties) cannot tolerate cold winter temperatures and must be protected from frost.

  1. Protecting Your Bonsai

Summer Care

During the hot summer months, protect your bonsai from intense afternoon sun. Ideal options include:

  • Placing the tree under shade cloth
  • Using a lath house
  • Keeping it in a partially shaded area of your yard

Morning sun is generally beneficial for most species.

Winter Care

During cold winter periods, protect your bonsai from prolonged freezing temperatures. You may:

  • Place the tree near the house under a covered patio
  • Move it temporarily indoors to a bright location
  • Use a heated greenhouse (ideal for enthusiasts)

Note: Tropical bonsai such as Ficus should be kept indoors or in a warm, protected area whenever temperatures approach freezing.

  1. Watering

Proper watering is the single most important part of bonsai care.

  • In most climates: water once daily
  • In cool, damp weather: every 2–3 days may be sufficient
  • In hot, dry weather: watering twice daily may be necessary

Always water thoroughly until water drains from the bottom of the pot. Never allow the soil to dry out completely.

  1. Fertilizing

Feed your bonsai regularly during the growing season (spring through mid-summer).

  • Feed approximately every two weeks
  • Diluted fish emulsion works very well
  • Most balanced fertilizers are suitable
  • Always dilute to about one-third of the label strength

Do not fertilize during the winter months.

  1. Pruning and Pinching

Regular pruning helps maintain the beauty and shape of your bonsai.

  • Trim whenever new growth disrupts the design
  • Use sharp bonsai scissors or small pruning snips
  • Frequent light trimming is better than heavy cutting
  1. Repotting and Root Pruning

Periodic repotting keeps your bonsai healthy and properly sized.

Typical schedule:

  • Young trees: about every 2 years
  • Mature trees: every several years

Best time: late winter to early spring (topicals can be repotted in summer).

Basic Repotting Steps

  1. Carefully remove the tree and gently remove about two-thirds of the old soil
    b. Prune approximately one-third of the roots
    c. Replant in fresh bonsai soil, eliminating air pockets
    d. Water immediately by placing the pot in a shallow pan of water (bottom watering)
    e. A chopstick or wooden dowel is very helpful for working soil between roots
  2. Soil and Pot Requirements

Good bonsai soil must retain moisture while also draining well and allowing air to reach the roots.

A simple and effective mix for many trees:

  • 1 part scoria (lava rock)
  • 1 part pumice
  • 1 part fir bark
  • Akadama may be used (if available) to improve water retention and root health

Choosing the proper bonsai pot is essential for the health and stability of your tree. Quality bonsai pots include drainage holes covered with mesh to prevent soil loss while still allowing excess water to drain freely.

Good drainage helps avoid root rot and keeps the soil properly aerated. It is also important to secure your tree in the pot using bonsai wire. Gently tie the tree with bonsai wire through the drainage holes to hold it firmly in place while the roots establish.

Properly securing the tree prevents movement that can damage new roots and helps the bonsai develop strong, stable growth.

  1. Keep Learning

Bonsai is a rewarding lifelong journey. As your experience grows, you will discover additional techniques and soil mixes that work best for your trees and climate.

With proper care, patience, and attention, your bonsai can bring beauty and enjoyment for many years.

Please note: These guidelines provide general bonsai care information. Actual care requirements may vary depending on your local climate, environment, and the specific species of your tree.

Enjoy Your Bonsai
