Temperature and Humidity

Maintaining appropriate temperature and humidity levels is vital for bonsai health.

• Temperature: Most bonsai prefer temperate climates. Avoid exposing them to extreme temperatures, whether hot or cold. Indoor bonsai should be kept away from drafts and heating sources.
• Humidity: Bonsai trees benefit from higher humidity levels. In dry environments, increase humidity by placing a humidity tray filled with water and pebbles beneath the bonsai or by misting the leaves regularly.

Fertilizing

Regular fertilization provides essential nutrients that may be depleted from the soil over time.

• Type of Fertilizer: Use a balanced fertilizer with equal proportions of nitrogen, phosphorus, and potassium (e.g., 10-10-10) or specialized bonsai fertilizers.
• Frequency: Fertilize during the growing season (spring and summer) every 2-4 weeks. Reduce or stop fertilizing in the fall and winter when the bonsai’s growth slows.
• Application: Follow the manufacturer’s instructions for dosage to avoid over-fertilization, which can harm the bonsai.

Pruning and Trimming

Pruning shapes the bonsai and encourages healthy growth.

• Branch Pruning: Trim back new growth to maintain the desired shape and promote ramification (branching). Use sharp, clean scissors or pruning shears to make precise cuts.
• Leaf Pruning: Remove excess leaves to reduce the size of the foliage and enhance the miniature appearance. This also helps improve air circulation within the canopy.
• Timing: Prune during the growing season when the bonsai is actively producing new growth. Avoid heavy pruning during dormancy.

Wiring

Wiring allows you to bend and shape the branches, helping to achieve the desired bonsai form.

• Choosing Wire: Use anodized aluminum or copper wire, typically 1-2 mm in thickness, suitable for the size of your bonsai’s branches.
• Application: Wrap the wire around the branch in a spiral, starting from the base and moving upward. Avoid wrapping too tightly to prevent cutting into the bark.
• Shaping: Gently bend the wired branches into the desired position. Leave the wire on for a few months, monitoring growth and ensuring the branch remains in place.
• Removal: Remove the wire before it starts to cut into the branch, typically after a few months, to prevent scarring.

Repotting

Repotting is essential to prevent the bonsai from becoming root-bound and to refresh the soil.

• Frequency: Repot every 2-3 years for younger bonsai and every 3-5 years for mature bonsai.
• Timing: Repot in early spring before the growing season begins.
• Process:
  1. Remove the Bonsai: Gently take the bonsai out of its pot, being careful not to damage the roots.
  2. Prune the Roots: Trim about one-third of the root system to encourage new growth and prevent overcrowding.
  3. Prepare the Pot: Clean the pot and ensure it has adequate drainage holes.
  4. Add Fresh Soil: Use a well-draining bonsai soil mix, such as akadama, pumice, and lava rock.
  5. Reposition the Bonsai: Place the bonsai back into the pot, spreading the roots evenly.
  6. Backfill and Secure: Add more soil around the roots, pressing gently to eliminate air pockets.
  7. Water Thoroughly: Water the bonsai to settle the soil and provide initial moisture.
