minimum temp for Nerine

Thank you Michael for checking Amazon! 17-21 C does make sense for
summer soil temp. And I also suspect that cooler winter temperatures
than 9C are acceptable in situ, if not in Dutch greenhouses -- I would
guess at least 3 months worth from Lee's Guernsey data.

One further note: I transplanted my few N. sarniensis ('Corusca major',
as it happens) about a month ago. They were growing in my local clay
with rather more shade than I'd intended. They had not received any
intentional supplemental water -- the soil was completely dry. The bulbs
were firm, large, and scaling nicely, but they did not have extensive
fleshy roots (at least not compared to the Boophane I inadvertently
disturbed during the transplant). They produced many leaves last year
but no flowers. I moved them to a hotter and drier spot, which may have
been a mistake... We'll see how they respond.

Best,

To summarize: plant in the fall and grow at 17-21C (62-70F). After
flowering is finished (around November in the northern hemisphere), reduce
temperatures to 9-12C (42-55F) or possibly lower -- temps lower than 9C were
not tested in the research. In the spring, gradually increase temperature
as the foliage starts to yellow. Bulbs are generally dormant by the end of
April, and should spend the summer in the 17-21C (62-70F) range.
