Selection Criteria:
1. Hardy in your zone (outdoor bonsai are healthier than indoor)
2. Tolerant of root pruning (essential for bonsai longevity)
3. Produces small leaves naturally or through technique (leaf reduction)
4. Available as nursery stock (don't start from seed — too slow for learning)
期待結果: 気候、経験、美的目標に合った樹種が選定される。
失敗時: 樹種の適性が不明な場合、ニレケヤキ(Chinese elm)をデフォルトとする。最も幅広い条件に耐え、初心者のミスを許容する。
構造的な作業(剪定、針金かけ、植替え)の前に、樹木と向き合って座る。
Bonsai Sitting Protocol (5-10 minutes):
1. Place the tree at eye level on a clean surface
2. Sit comfortably at arm's length
3. Observe without planning:
- Where does the trunk move? Follow its line from base to apex
- Which branches reach toward light? Which retreat?
- Where is the tree's natural front? (The side that tells its story)
4. Resist the urge to "fix" anything. The tree has been growing
toward its own form. Your job is to listen first, then collaborate.
5. When you feel you understand the tree's intention, you may begin work.
If you feel rushed or impatient, you are not ready. Return tomorrow.
期待結果: 穏やかで急がない状態。樹木の自然な動きと個性への理解。
失敗時: 計画する心を静められない場合、構造剪定に進まない。水やりや施肥などの維持管理はこのチェックポイントなしでも続けてよい。
2つの種類がある: 維持剪定(継続的)と構造剪定(季節的)。
Maintenance Pruning (any time during growing season):
- Purpose: Maintain shape, encourage ramification (branching density)
- Tool: Sharp bypass secateurs or bonsai scissors
- Technique:
- Deciduous: Cut back new shoots to 2-3 leaves once they extend to 6-8 leaves
- Conifer: Pinch new candles by hand (never cut — it browns the needles)
- Remove: Crossing branches, upward-growing interior shoots, dead wood
Structural Pruning (late winter for deciduous, early spring for conifer):
- Purpose: Establish or refine the tree's fundamental shape
- Tool: Concave cutter (creates a wound that heals flush)
- Technique:
1. Identify the primary trunk line
2. Select 3-5 primary branches (alternating left/right, decreasing in thickness upward)
3. Remove competing leaders, bar branches (directly opposite), and wheel branches (multiple from same point)
4. Cut flush to trunk with concave cutter — do NOT leave stubs
5. Never remove more than 1/3 of foliage in one session
⚠️ CAUTION: Structural pruning is irreversible. If uncertain about
a branch, leave it for one more season. You can always remove later;
you cannot reattach.
期待結果: より整理されたシルエット、改善された光の透過、明確な幹線を持つ樹木。
失敗時: 葉を取り過ぎた場合、木漏れ日が当たる保護された場所に移動する。水やりをやや減らす(葉が少ない=蒸散が少ない)。新芽が出るまで施肥しない。
アルマイト処理されたアルミニウムまたは焼きなました銅線で枝を巻いて整枝する。
Wiring Protocol:
1. Select wire gauge: approximately 1/3 the diameter of the branch
2. Anchor wire by wrapping 2-3 turns around the trunk or a thicker branch
3. Wrap at 45° angle along the branch — consistent spacing, not too tight
4. Bend SLOWLY — listen for cracking. If you hear a crack, stop immediately
5. Wire in pairs: two branches of similar thickness with one piece of wire
Timing:
- Deciduous: Wire in winter (no leaves = better visibility)
- Conifer: Wire in late autumn (flexible sap)
Removal:
- Check monthly during growing season
- Remove BEFORE wire bites into bark (scarring is permanent)
- Cut wire off in small sections — never unwrap (risks branch breakage)
Common Errors:
- Wire too thin: branch springs back to original position
- Wire too tight: cuts into bark, leaves permanent scars
- Bending too fast: branch snaps at the wire point
期待結果: 樹皮を傷つけることなく枝が希望の位置に保持される。針金は3〜6ヶ月で除去する。
失敗時: 針金が樹皮に食い込んだ場合、直ちに切り取る。傷跡は2〜3成長期で治癒する。深い傷には切口保護剤を塗布する。
根が鉢の内側を回っている場合や、用土の排水性が低下した場合に植替える。
Repotting Protocol:
1. Timing: Early spring, just as buds begin to swell (species-dependent)
- Deciduous: When buds are visibly swelling but not yet open
- Conifer: When new candles begin to elongate
- Tropical: Any time in active growth (but spring is still safest)
2. Prepare soil mix:
- Standard: Akadama 1 : Pumice 1 : Lava rock 1
- Moisture-loving species: Add 1 part organic (bark or peat)
- Arid species: Increase pumice ratio to 2 parts
- Sift all components through 2mm and 6mm screens — discard dust and oversized
3. Remove from pot:
- Run a root sickle around the pot interior
- Lift tree gently — if stuck, do NOT pull by trunk
- Use a chopstick to gently untangle the root mass from the outside in
4. Root pruning:
- Remove no more than 1/3 of root mass
- Cut circling roots back to where they radiate outward
- Trim long taproots to encourage lateral feeder roots
- Preserve fine, white feeder roots — these are the tree's lifeline
5. Place in pot:
- Secure drainage mesh over holes
- Thread anchor wires through drainage holes
- Add a layer of soil, position tree, tie down with anchor wires
- Fill around roots with chopstick — no air pockets
- Top-dress with fine akadama or moss
6. Aftercare:
- Water thoroughly until water runs clear from drainage holes
- Place in sheltered spot — no direct sun for 2-3 weeks
- Do NOT fertilize for 4-6 weeks (new roots need to establish)
期待結果: 樹木が鉢の中で安定し、水やり時に用土が自由に排水され、幹にぐらつきがない。
失敗時: 植替え後数日以内に深刻な萎れが見られる場合、根を切り過ぎた可能性がある。日陰に移動し、毎日葉に霧吹きし、次の水やり時に発根促進剤を加える。回復には4〜8週間かかる。
植替えから2週間後に樹木の回復を評価する。
Post-Repot Health Triage:
┌──────────────────┬────────────────────────┬─────────────────────┐
│ Indicator │ Healthy │ Stressed │
├──────────────────┼────────────────────────┼─────────────────────┤
│ New buds │ Swelling or opening │ Static or browning │
│ Leaf colour │ Normal or light green │ Yellowing or wilting│
│ Soil drainage │ Water flows through │ Pools on surface │
│ Trunk stability │ Firm, no wobble │ Rocks when touched │
│ Root zone smell │ Earthy, neutral │ Sour or musty │
└──────────────────┴────────────────────────┴─────────────────────┘
If 3+ indicators show stress:
1. Move to dappled shade
2. Reduce watering frequency (but don't let soil dry completely)
3. Mist foliage morning and evening
4. Do NOT fertilize — stressed roots cannot absorb nutrients
5. Reassess at 4 weeks
期待結果: 2〜3週間以内に新芽の活動と安定した足場が見られる。
失敗時: 6週間経っても新芽がなく、ストレス指標が改善しない場合、盆栽鉢から取り出し、標準的な培養土を入れたより大きな回復用容器に1成長期間置く必要があるかもしれない。
Bonsai Seasonal Calendar (Temperate Zones):
┌─────────┬──────────────────────────────────────────────────┐
│ Season │ Tasks │
├─────────┼──────────────────────────────────────────────────┤
│ Spring │ Repot (early). Begin fertilizing (balanced). │
│ │ Structural prune before bud break. Remove wire │
│ │ from autumn. Move outdoor trees to growing area. │
├─────────┼──────────────────────────────────────────────────┤
│ Summer │ Maintenance pruning ongoing. Water daily (twice │
│ │ in heat). Reduce fertilizer in peak heat. Watch │
│ │ for pests (aphids, spider mites). Shade conifers │
│ │ from afternoon sun if > 35°C / 95°F. │
├─────────┼──────────────────────────────────────────────────┤
│ Autumn │ Wire deciduous trees after leaf fall. Final │
│ │ fertilize with low-nitrogen (0-10-10). Let │
│ │ deciduous leaves fall naturally — don't strip. │
│ │ Reduce watering as growth slows. │
├─────────┼──────────────────────────────────────────────────┤
│ Winter │ Protect from hard freeze (unheated garage or cold │
│ │ frame for temperate species). Water sparingly — │
│ │ soil should be just moist. Study, plan, sharpen │
│ │ tools. Contemplate the tree's bare structure. │
└─────────┴──────────────────────────────────────────────────┘
期待結果: 季節の移り変わりに合わせた年間管理リズムが確立される。
失敗時: 季節の作業を逃した場合(例:春の植替え)、来年まで待つ。時期外れの植替えは待つことより危険である。
