Overview
Bamboo Bonsai (Bambusoideae / dwarf bamboo species) is a evergreen grass used for forest, clump and accent-style bonsai displays. It is best suited to group plantings, landscape trays, accent plantings and modern bonsai displays. For UK growers, treat it as: Mostly outdoor, some tropical types indoors with strong light.
Placement
bright outdoor light or very bright indoor light for tropical types
Watering
keep consistently moist; bamboo dislikes drying out in shallow pots
Feeding and fertilising
feed well during active growth to support new culms
Pruning and wiring
thin old culms and trim leaves to keep scale; wiring is rarely useful
Repotting
divide and repot every 1-2 years because roots fill pots quickly
Propagation
division is the normal method
Pests, diseases and common issues
root congestion, dried leaf tips, spider mites indoors and invasive runners if planted outside
