When to Repot Juniper Bonsai
The optimal time to repot juniper bonsai is during early spring or late fall, when the tree is dormant and less susceptible to stress. If your bonsai exhibits signs of poor health, such as yellowing leaves, stunted growth, or root rot, an immediate repotting may be necessary.
Materials Required
- New bonsai pot with drainage holes
- Well-draining bonsai soil mix (e.g., akadama, pumice, lava rock)
- Sharp bonsai scissors or shears
- Root hook or chopstick
- Watering can or hose with nozzle
- Wire (optional)
Step-by-Step Repotting Process
1. Prepare the New Pot
- Choose a new pot that is slightly larger than the current one, allowing for root growth.
- Ensure the pot has adequate drainage holes to prevent waterlogging.
- Fill the pot with a layer of bonsai soil mix to a depth of about one-third.
2. Remove the Bonsai from the Old Pot
- Carefully tip the bonsai out of its old pot.
- If the roots are tightly bound, gently loosen them with a root hook or chopstick.
- Avoid damaging the delicate roots.
3. Prune the Roots
- Use sharp bonsai scissors or shears to prune away any dead, damaged, or excessively long roots.
- Cut at a diagonal angle to promote new root growth.
- Remove approximately 20-30% of the overall root mass.
4. Prepare the Bonsai for Repotting
- Gently spread out the remaining roots and remove any tangled areas.
- If desired, wire the roots to the base of the trunk to secure them in the new pot.
5. Place the Bonsai in the New Pot
- Position the bonsai in the center of the new pot.
- Spread out the roots evenly and fill in the remaining space with bonsai soil mix.
- Gently tamp down the soil to remove any air pockets.
6. Secure the Bonsai
- If necessary, use wire to secure the bonsai to the pot.
- Wrap the wire around the trunk and the rim of the pot, ensuring it is tight but not constricting.
7. Water and Care
- Water the bonsai thoroughly after repotting.
- Place the bonsai in a shaded location for a few weeks to allow it to recover.
- Gradually increase sunlight exposure as the bonsai stabilizes.
Post-Repotting Care
- Keep the soil moist but not soggy.
- Fertilize the bonsai every 2-3 weeks during the growing season.
- Monitor the bonsai for signs of stress and adjust watering and care accordingly.
