Growing Amaryllis under Lights
Wed, 16 Nov 2005 12:32:40 PST
I have a collection of southern garden "passalong" amaryllis, in pots, that
I just leave out in a minimum-heated greenhouse (32-35F) for the winter
(mostly H. xjohnsonii and H. puniceum, or whatever the orangey one is,
types).  I might water on rare occasions if they seem dusty dry, but
otherwise I just leave them alone (this includes a big potful of H.
papilio, by the way).  Depending on what they are, they then bloom sometime
between spring and fall.  They get fertilized in spring with some Nutricote
w/minors - the 100-day formulation, and I forget the balance - and repotted
when they really can't fit in their pots anymore.  Seems to suit them fine,
and it leaves the windowsills free in winter for my pet orchids.

I grow many South African bulbs under lights in the basement.  I use 
either a metal halide HID or a sodium HID.  The sodium has an orange 
color that can made the flowers look off color.  I run the light twelve 
hours per day and use a small fan to provide some air movement. 

A would question the effort to continue to grow the amaryllis, a rest 
period can be necessary to induce flowering.  I place my amaryllis in 
the basement in a dark spot and withhold water and give a drink only 
when I see the emergence of a flower spike.
