Alocasia 'Polly' (African Mask Plant)の育て方・育成方法は？
| 光量 | Bright indirect light; direct sun scorches; lower light just slows growth |
|---|---|
| CO₂ | Medium to high humidity (pebble tray, grouping, humidifier); no figure in sources |
| 水温 | ≥ 15°C |
| 配置 | NOT for typical terrariums – too large ('Polly' is roughly 10–60 cm) and rot-prone in a sealed jar. Possible only in a large, ventilated vivarium or paludarium. Small "jewel" alocasias are the better terrarium pick. (Sources do not cover terrariums directly; this is based on size and rot risk.) |
| 生長速度 | Moderate |
| 難易度 | Moderate |
| 科名 | Araceae |

Alocasia 'Polly' (African Mask Plant)によくあるトラブルや病気は？
Root or stem rot from overwatering, especially when cool; red spider mite (fine webbing, speckled leaves) in dry air; brown leaf edges from low humidity; winter die-back from cold / semi-dormancy.
Alocasia 'Polly' (African Mask Plant)のトラブルや枯れへの対処法は？
In growth, water freely and let the top ~5 cm dry; cut right back in winter to avoid rhizome rot. Draining mix (compost with perlite or grit about 3:1). Liquid feed every 2–3 weeks spring to autumn. Keep above 15°C; sources vary (10–16°C), so this is the safe figure.
