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

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

Hi, Just want to ask where can I buy watermelon seed?
14 Oct 12, Chantelle (Australia - temperate climate)
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...

''ýou'll never never know if u don't give it a go" From my expeirence of using wicking beds, as long as u have set up your bed correctly, watermelons should grow successfully,provided they get adequate summer heat. I experienced 46C on the day of the Victorian Black Saturday bushfires, the only vegetable bed that didn't die on that day was the one set up as a wicking bed. I rest my case.
