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.

Watermelon seeds can be bought at most nurseries,a hardware giant eg. Bunnings (where I got mine and are good with seeds) a good 2 dollar shop, a hardware store, or a discount superstore eg. Kmart, target. hope this helps

Hi my friend has a watermelon plant that has gone berserk vine-ing everywhere. Only thing there are lots of flowers and bees have been seen to hover over them but no fruit as yet. How can we tell which are male / female flowers? I can't find any "bulbing" as in female pumpkin flowers but when I touch the middle of the flowers no pollen comes away so I don't think that's the male...
