Bonsai Tree Care Guide Online: Finding Expert Guidance & Supplies

The internet is the modern bonsai library—but like any library, you need to know which shelves hold the authoritative texts. Here's how to find expert guidance and reliable supplies online.

Vetting Online Guidance

• Author credentials: Professional bonsai artist, nursery owner, club instructor, published author.
• Regional relevance: Climate-matched advice (zone, rainfall, heat/cold extremes).
• Species specificity: "Bonsai care" is useless. "Japanese maple bonsai in Zone 7" is actionable.
• Currency: Updated for new pests, techniques, climate shifts.
• Community validation: Referenced on Bonsai Nut, International Bonsai Club, Reddit r/bonsai.

Top-Tier Online Resources

• Bonsai Empire (bonsaiempire.com): Structured courses, species guides, technique videos.
• Bonsai Nut (bonsainut.com): Forum—deep threads, build-alongs, expert Q&A.
• International Bonsai Club (internationalbonsaiclub.com): Articles, gallery, community.
• Mirai Bonsai / Bonsai Mirai (Ryan Neil): Professional-level technique, species deep-dives.
• University Extensions (.edu): Pest/disease ID, horticultural science.

Buying Supplies Online: Trusted Sources

Red Flags

• "Complete bonsai kit" with seeds, pot, soil, tools for $30.
• "Indoor pine/juniper" — temperate species marketed as houseplants.
• Generic "bonsai soil" — usually peat/perlite, not inorganic mix.
• No species Latin name, no care specifics.

Curate your digital library like your tool kit: quality over quantity, specialists over generalists.
