🌳 Gardenwise Slow Release Bonsai Fertilizer — Professional 18-5-10 NPK Pellets

Most bonsai fertilizers are generic. This one was built specifically for bonsai — with an 18-5-10 NPK ratio that prioritizes strong foliage, balanced root development, and long-term tree health over a quick green flush that fades in two weeks.

One application feeds your tree for 6–8 weeks. No guessing, no burning, no weekly liquid feeding schedules. Just healthy, steady growth the way bonsai growers want it.

━━━━━━━━━━━━━━━━━━━━━━
🌱 WHY 18-5-10 — AND WHY IT MATTERS FOR BONSAI
━━━━━━━━━━━━━━━━━━━━━━
NPK ratio determines what your tree prioritizes. The 18-5-10 formula is specifically balanced for bonsai because:

- High nitrogen (18) — deep green foliage, strong canopy, vigorous back-budding
- Moderate potassium (10) — root strength, stress resistance, and winter hardiness
- Low phosphorus (5) — encourages compact, ramified growth rather than excessive flowering
- Added micronutrients — iron, manganese, zinc, copper, and boron for color, texture & immunity

This is not a generic all-purpose fertilizer diluted and repackaged. It's calibrated for the compact root zone and shallow containers bonsai live in.

━━━━━━━━━━━━━━━━━━━━━━

- Use bonsai fertilizer baskets (little mesh cups) to keep pellets contained and easy to remove
- For tropical indoor bonsai (Ficus, Fukien Tea), feed year-round at reduced amounts in winter
- For Japanese Maple and other deciduous trees, stop feeding 6 weeks before first frost
- For Junipers and pines, prioritize fall feeding for strong winter root development
