Mike:
One of the guiding principles regards bulbs splitting and making many corms is depth of planting.  I've found that shallowly planted bulbs tend to split and make many smaller offsets.
I'd try a couple planted deeper and see if it makes a difference.

Subject: [pbs] Gladiolus cormules

Having grown them in the past and again last season, the cormules of G
dalenii seem to stay the same size the first year after being planted out.
Dug in the fall, the yearlings produced more, even smaller, cormules rather
than grow larger.  Is this the case in most species?  The other
consideration is soil fertility.  The location is a heavily amended
vegetable garden.  Is a leaner soil better in this circumstance?  The
mature corms produced 3-4 large blooming size offsets along with hundred of
cormules.  They are lifted each year.  Another grower in the area said hers
in the ground, not lifted, bloom poorly after a few years of being
overcrowded. Is there another method for cormule cultivation better suited
to increase size?

Thank you,
