SYBASoil Bonsai Mix – Free-draining technical substrate for bonsai

1. Expert introduction

The SYBASoil Bonsai Mix is a substrate specifically formulated to meet the very particular constraints of bonsai cultivation. In a shallow pot, with a deliberately limited root volume, a bonsai requires a stable, free-draining and perfectly aerated soil in order to avoid any suffocation of the roots.

In the TerraLED approach, success with a bonsai indoors or in a greenhouse depends on consistency between controlled lighting, precise watering and a suitable substrate. This mix fits fully into this technical, long-term logic.

2. What is this product actually for?

SYBASoil Bonsai Mix makes it possible to:

• Promote constant oxygenation of the roots
• Prevent the substrate from compacting over time
• Ensure rapid drainage while retaining a useful water reserve

Suitable plants and environments:

• Indoor and outdoor bonsai (deciduous trees and conifers)
• Growing in shallow pots
• Bright environments with controlled watering

Not recommended for:

• Conventional non-woody indoor plants
• Plants that prefer fine, rich substrates
• Terrariums with animals (contains perlite, fertiliser and activated charcoal)

3. Practical examples of use

Indoor bonsai: A substrate perfectly suited to maples, ficus, elms or other species grown under TerraLED LED grow lighting.

Outdoor bonsai in pots: Can be used when repotting to maintain a lasting free-draining structure, limiting the risk of standing water.

Technical decorative growing: Suitable for botanical installations requiring precise control of drainage.

4. How do you use this product correctly?

• Gently remove the old substrate
• Lightly rinse the roots with lukewarm water
• Place a layer of Bonsai Mix in the bottom of the pot
• Position the tree and fill in without firming excessively
• Water generously after repotting

Best practices: Fertilise regularly during the growing period, as the volume of substrate is limited. Adjust watering to the bonsai species.

Common mistakes: Constantly waterlogged substrate, lack of light, no fertilising.
