When the tree needs to be re-potted.

Hawaiian Schefflera/ Umbrella Tree

Schefflera arboricola

When the tree becomes almost root bound or doesn't drain properly it needs to be re-potted. Bonsai soil is very coarse, with many spaces for air. It is good for the long-term health of the plant. Fine material has to be removed to avoid compacting the soil, which would exclude air. Think about the weather your plants will experience.

Lava Soil Additive

A new shipment of Lava Soil Additive is in!

Lava Rock is a naturally occurring, paramagnetic, mineral rich volcanic cinder that has a porous structure which makes the material lightweight and highly moisture retentive.

Incorporate into your Bonsai soil mix to increase drainage (aeration). It will absorb up to 40% of its weight in water. Small lava gravel (1/4 to 3/8 inch) is the best component because it has very "sharp", irregular surfaces, which help to produce a well branched root system.

This soil additive is considered by many to be an excellent source of energy for the soil.
