Eriocaulon cinereum (Pipewort)のトリミングや増やし方は？
No leaf trimming — just remove decaying outer leaves, and cut flower stalks if you don’t want them. Propagate by carefully separating daughter rosettes (roughly monthly in good conditions); avoid moving the plant, as its long roots are easily damaged. Eriocaulon sp. ‘Vietnam’ — a related trade form, taller with bright-green needle leaves, used as a midground accent — is also divided and responds poorly to trimming.
Eriocaulon cinereum (Pipewort)によくあるトラブルや病気は？
Leaves melting after planting as nursery-grown emersed plants switch to submersed growth; weakening or die-back after flowering, which costs a lot of energy (in the wild it behaves as an annual); algae on the rosette because it grows slowly under strong light.
Eriocaulon cinereum (Pipewort)のトラブルや枯れへの対処法は？
Plant into deep, rich aquasoil with the roots fully covered; emersed-grown plants can be laid on their side (held with a stone) so new growth turns upward without the old leaves rotting at the crown; keep CO₂ stable and wait for submersed leaves. After flowering it may regrow from the base — keep offsets as backup. Balance nutrients and CO₂, add root tabs and algae grazers. Most sources advise soft, acidic water, though Tropica says this species copes with medium-hard water better than most of the genus.
