1. Grow in the open ground, they hate pots
2. Choose full light, or only partial shade for some of the day; humid shelter is important, they hate a dry wind
3. The soil should be heavy, moisture retentive and nutritious. E.g. a clay-rich loam with added rotted compost, well-rotted animal manure and leaf-mould.
4. The soil should never even hint of dryness.
5. Some (P. bulleyana, prolifera, secundiflora, poissonii, wilsonii) will tolerate prolonged waterlogging. Others (P. japonica, pulverulenta, aurantiaca, chungensis, cockburniana) hate it.
6. Deciduous species are extremely hardy (to zone 4-5). Evergreen species (prolifera, poissonii, wilsonii) less so (zones 7-8). Most dislike summer heat (>28C)
7. P. cockburniana and to some extent P. chungensis are short-lived and need regular renewal from seed.
