Complete Bonsai Plant Care: Watering, Repotting, Soil & Species Needs

Bonsai care is horticulture distilled to its essence—every input amplified, every mistake magnified. Master these fundamentals, tailored to your species and environment, for trees that outlive you.

Watering: The Daily Discipline

Never schedule. Check daily (chopstick/finger). Water thoroughly until free drainage. Species matrix:

• Deciduous (maple, elm): Consistent moisture; wilt = damage.
• Conifers (pine, juniper): Slight drying between; tolerate drought better.
• Tropicals (ficus, jade): Consistent warmth/moisture; no frost.

Soil: Free-draining mix (akadama/pumice/lava + organic). Prevents rot, ensures oxygen.

Repotting & Root Pruning

Frequency: Young (1–2 yrs), developing (2–3), mature (3–5+). Timing: Early spring (bud swell) for most; late winter for some conifers; summer for tropicals. Process: Remove tree, comb roots, trim 1/3–1/2 thick roots, refresh soil, settle with chopstick. Aftercare: Shade 2 weeks, no fertilizer 4 weeks, mist foliage.

Soil Mix Formulas

• Classic (Boon): 1:1:1 akadama:pumice:lava.
• Conifer: 2:1:1 akadama:pumice:lava (more water retention).
• Tropical: 1:1:1 akadama:pumice:peat/bark.
• Budget: 50% screened native soil, 50% compost + perlite.

Fertilization

Growing season only. Balanced organic (5-5-5) or specialized. Schedule: Weekly liquid (dilute) or monthly solid cakes. Stop: 6 weeks before frost (temperate); reduce winter (tropical).

Tools & Location

Essential tools: Concave cutter, bud scissors, wire cutters, knob cutter, root rake, chopsticks, sieves. Location: Match species to sun/wind/cold. Most need outdoors. Tropicals: bright window + grow light.

Know your species. Observe daily. The tree teaches the rest.
