Step-by-Step Guide

Before starting the repotting process, it is essential to assess the condition of your bonsai.

1. Check if the bonsai is firmly rooted in the pot; it should come out easily.
2. Inspect the roots for growth and signs of health.

Carefully remove the old, broken-down soil from around the roots.

1. Use a chopstick or similar tool to gently tease away the soil without damaging the roots.
2. Identify structural and feeder roots while removing as much old soil as possible.

If the soil is too degraded, consider bare rooting the tree.

1. Completely remove all old soil, ensuring you maintain some healthy roots.
2. Clean the roots thoroughly to assess their condition.

Once the roots are clean, prune any circling or unwanted roots.

1. Make clean cuts to encourage healthy growth.
2. Focus on maintaining a balance between strong structural roots and healthy feeder roots.

Select a suitable pot and prepare it for replanting the bonsai.

1. Ensure the drainage holes are clear and use mesh to prevent soil loss.
2. Add a layer of fresh substrate to create a mound for the roots.

Position the bonsai in the new pot, ensuring a stable base.

1. Carefully spread the roots over the mound of soil.
2. Fill in the gaps with fresh substrate, making sure not to damage the roots.

After planting, water the bonsai thoroughly and add a top dressing.

1. Water until it drains from the bottom to ensure good moisture.
2. Apply a light layer of moss to retain moisture and protect the roots.

1. Always repot in spring when the tree is waking up from dormancy.

3. Fertilize lightly after repotting to support new growth.
