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...

Hi folks, I'm looking for a good variety suited to manly nsw climate. That is to say, coastal, temperate/sub tropical.

I have grown the variety Sugar baby succesfuly around Byron Bay. The melons are the best I have ever had, juicy and extremely sweet and they seem to suit warm climates. You can buy the seeds from places like Bunnings or Mitre 10, or if you want organic seeds then there is great supplier called Greenpatch Seeds based in Taree that will post you seeds for $2. Good Luck!

''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.

Rosie, maybe your nights aren't warm enough yet? They grow best with days 20-35C and night temperatures over 18C.
