Hi,

I had a pot of Amaryllis belladonna whose contents had become too large,
so towards the end of Summer I tipped it out and split up the bulbs.
Probably 30 decent sized ones.

Four of them I sent to someone and at least one of them then flowered.

The others I re-potted, including leaving the central group of bulbs
intact.

None of the ones I kept have flowered.

I have the idea that whether a bulb flowers or not is predetermined,
there's a flower in there which will come out regardless - which seems
to hold with things like daffodils. That one could do a ultrasound scan
of the bulb and see the flower in there.

Or there's the idea that whether the bulbs flower depends on the
preceding season, or maybe the dormant season.

My "experiment" seems to show that flowering depends on the last couple
of weeks of dormancy, how the dormant season ends.

There was no difference in how I treated my bulbs and the ones I sent
away. I kept them all in the same media and shipped them in it.

If you want your Amaryllis belladonna to flower send them to someone else.
