Bonsai Pruning Schedule Calculator

Know exactly when and how to prune your bonsai. Species-specific schedules for healthy trees.

Age of the bonsai tree

Base Frequency × Climate Factor = Weeks Between Pruning
Maple, 5 years, training stage, temperate: Every 4 weeks, cut to 2-3 leaf pairs

How often should I prune my bonsai tree?

Pruning frequency depends on species and stage. Deciduous trees: Every 2-4 weeks during growing season (spring-fall). Conifers: Once or twice per year (late spring, early fall). Tropical trees: Year-round, every 3-4 weeks. Flowering trees: After blooms fade, before next bud set. Young training trees need more frequent pruning than mature maintenance trees.

What is the difference between structural and maintenance pruning?

Structural pruning shapes the tree's basic form - removes large branches, establishes trunk taper, sets primary branches. Done in late winter/early spring when tree is dormant. Maintenance pruning maintains the shape - trims new growth to 2-3 leaf pairs, removes water sprouts, keeps silhouette clean. Done throughout growing season. Never do heavy structural pruning in fall.

When is the best time to prune bonsai?

Deciduous: Late winter/early spring for structural, throughout growing season for maintenance. Flowering: After flowers fade (pruning removes flower buds). Conifers: Late spring as candles extend, early fall for final trim. Tropical: Any time, avoid heavy pruning before winter. Never prune during extreme heat, cold, or when tree is stressed (repotting, pest issues).

How much can I cut off at once?

Never remove more than 30% of foliage in one session - tree needs leaves for photosynthesis. For major reductions, do over 2-3 years. Pine trees: Never remove all old needles - they need existing foliage for energy. Junipers: Never cut back to bare wood - they won't back-bud from old wood. Ficus and elms are exceptions - they back-bud readily and can handle severe pruning.
