Do I need more than one watermelon plant growing to pollinate between or would one plant bear fruit? Thanks for any help.

You need bees to pollinate watermelon

Hi James.. Watermelons are self pollinating, so only one plant is needed, unless you are growing seedless melons which require a pollinator.
