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...
