3/4 of an inch around and it's sticking out of the substrate? I'd say you didn't have enough substrate.
Plants use rhizomes, tubers, bulbs to store food for lean times or dormancy. It isn't going to get smaller too much woody material to hold it's shape. Might shrink a smidge if you starved the plant.
I don't think apongetons have true bulbs, more of a rhizome which is a modified stem used for storage and stabilizing the plant. Just like bearded irises and they don't shrink noticeably during dormancy. It's only going to grow or die.
