The gladiola corms have already sprouted and are pointing sideways because they weren’t cleaned until now. Do I let them sit and wait for the sprouts to straighten up or plant as is? If I do that, will they straighten up as they grow – reaching for the sky?

Go ahead and plant them as normal.
The Corms should correct themselves.
