flowering early or late?

[Diane Whitehead]

Usually it is obvious when an arisaema is going to flower - it comes out
of the ground with a bud, or is fatter than one that is not going to
flower.

Is it possible to fertilize a non-flowering plant, and make it grow
vigorously enough to flower later in its season?

When is the flower bud produced - while the corm is dormant, or can it be
produced while the plant is leafed-out?
