Root-over-rock: a staged relationship
In sekijoju, roots descend over a rock toward the soil below. The roots must thicken and fuse visually with the scene over time; a newly wrapped root is not yet an old-looking feature. Protect roots while they establish, maintain moisture without waterlogging, and avoid exposing the developing system to repeated disturbance.
Rock planting: the stone is the growing environment
In ishitsuki, the tree grows in a cavity or pocket associated with the rock, with the visible composition suggesting a landscape. The small substrate volume can dry and heat quickly. Water management is therefore dictated by the actual setup, weather and species, not by a bonsai-wide schedule.
Secure first, style second
A moving tree can shear fine roots or shift the stone. Plan stable anchoring, drainage and a safe display base before detailed styling. Choose a species adapted to the local climate and the available root space. The rock should support the tree’s visual story without compromising its basic needs.
A project measured in seasons
The convincing result comes from gradual root development, not a single mounting day. Photograph the same view over time and record watering, protection and root progress; this makes the horticultural work visible as well as the finished design.
