Warty, fucked up pumpkins are my favorite. I buy one every year - always wider than it is tall by tradition. Like this. (____)
And every year this pumpkin is named Gargus.
I encourage you to do this too.
So, are those galls due to infection, or are they something else? I know some species of insects will intentionally create galls on plants to store/feed larvae, too.
