Repotting Your Bonsai: A Guide to Healthy Growth

Repotting Your Bonsai: A Guide to Healthy Growth

Repotting your bonsai regularly is essential to prevent it from becoming pot-bound and undernourished. This process gives your tree fresh soil, space to grow, and encourages healthy root development.

When is it Time to Repot?

  • Frequency: Most bonsai trees will need repotting every 2 years, but some species may need it more or less frequently.
  • Check in Spring: The best time to check is early spring when the buds are just starting to swell. If the roots are tightly circling the pot, it's time!
  • Repotting = Spring Growth Boost: Repotting early in the season gives your tree the best chance to recover quickly and put out new growth.

Choosing the Right Soil Mix

A well-draining yet moisture-retentive soil mix is key. We have a large selection of soils right here for you to choose from.

The Repotting Process: A Step-by-Step Guide

  1. Gather Tools: Knife, scissors, wire cutter, chopstick, root rake
  2. Remove Tree: Gently loosen the tree from its pot.
  3. Evaluate Roots: If tightly packed, it's time to repot.
  4. Remove Old Soil: Carefully untangle roots, preserving as much as possible (especially important for pines!)
  5. Prune Roots: Trim any overly long roots (no more than 30% total).
  6. Prepare Pot: Cover drainage holes with mesh and secure with wire.
  7. Drainage Layer: Add a base layer of coarse material.
  8. Position Tree: Place the tree, securing it with wire.
  9. Add Soil: Fill with bonsai mix, working it around the roots.
