As so many lovely plants
Not for me
My poly-tunnels are +0ºC

The good thing
It stops me collecting plants at this temperature ;D

I have made nothing special - same treatment like my other summergrowing amaryllids - maybe better fertilizing ?
since last year I use Phostrogen

Thanks Hans,

I'm growing carmiolii, dubia and viridiflora and not one has yet to flower. How large is your bulb of dubia? My largest is carmiolli with a bulb about the size of a softball, I wonder how large they must be to bloom?

I will up my fertilizing regimen and cross my fingers!

I grow also carmioli,cinerea,dubia,haurii,tunguraguae,viridiflora...

to the size :
I dont know the size of a softball - my P.dubia bulb has a diameter of 5cm

I have my 4 species in my Clivia greenhouse, where the temperature sometimes is as low as +5°C in winter. They did not bloom this year, and the temperatures were not so cold as that.

Post by: Rogan on August 23, 2012, 03:16:32 PM: I grow my species outdoors the year round where the temp. does occasionally dip one or two degrees below freezing (0'C) at night, but then up to the mid 10's or 20's during the day - no damage at all and they flower well.

Post by: jshields on August 23, 2012, 07:56:57 PM: I can't help wondering how I ought to be growing my Phaedranassa (cinerea, dubia, viridiflora, and one other species) to get more reliable bloom. Do they need regular repotting, or do they resent disturbance? Would heavier feeding help? Mine get regular liquid feeding when watered (100 ppm N), but have not been repotted in years. As mentioned before, winter temperatures run around 45 - 50 F at night, upper 60s to about 80 F on sunny days. Summer is warm in the greenhouse, usually 85 - 90 F in daytime with cooling. Year-round shade cloth cover overhead.
