Pogostemon erectus (P. deccanensis)のトリミングや増やし方は？
Needs frequent pruning: top stems with sharp straight scissors at the height you want; replant the tops to thicken the group, or cut and replant the whole group for the cleanest look. Tops root quickly (about 5 – 10 days) and the cut stem pushes side shoots — strip the lowest 2 – 3 whorls and plant 2 – 3 cm deep, 2 – 3 cm apart.
Pogostemon erectus (P. deccanensis)によくあるトラブルや病気は？
Leggy, sparse stems from too little light; lower leaves yellowing or dropping from crowding/shade or nitrogen shortage; stunted, curled tips from fluctuating CO₂ or low calcium; stems melting after sudden parameter changes or poor circulation at the base.
Pogostemon erectus (P. deccanensis)のトラブルや枯れへの対処法は？
Raise light; thin and space stems and check nitrate; keep CO₂ steady and raise GH if the water is very soft; keep parameters stable and improve flow. It is a strong root feeder — use rich aquasoil plus regular complete liquid fertiliser.
