I am planning to recieve some D. arcturi material in a week or two. The thing I'm most worried about is the dormancy. I've been researching, and here's what I have so far:
Altitude: 1400m - 1080m to sea level.
Not self pollinating; need to pollinate.
Grow on banks of streams.
- Organic: “Deep sphagnum beds”, wet sandy clay soil, “Damp peat”, “sedge peat”, pure LFS
- Inorganic: pure gravel, could put dead sphagnum an inch or two underneath for humidity.
- Plants growing in gravel have their rhizome above ground. Plants in organic mixes have rhizome just below ground level, shallowly buried.
D. arcturi produces a rhizome up to 15cm long. With every year of age, the plant’s rhizome grows 1cm.
Weather: Cloudy, humid, moist winds
Dormancy: Dormant from October to April/May - light frosts?
I have no more clue about dormancy, a phase which is incredibly important for this species. Any more advice would be greatly appreciated.
