Dwayne top info, thanks mate

How did you get the plant? Did you start if from seed or did you get a
watermelon plant? If you started it from seed, did you start it inside or
did you plant it direct? What kind of climate are you in?
I grew them from a pack of seeds i bought at the supermarket, i just sewed
one row of about 20 seeds. 2 sprouted, i ripped the smallest one and let the
other keep growing. Im in Perth so the cooler temps are starting to kick in
now

If I remember correctly, the male blossoms develop first and then the
female.
Now ill just have to figure out which flower is which gender! Well, either
that or simply brush every flower which i guess would be almost equally as
effective

I have never heard pro or con, but I would think that ants can help with
your pollination also.
yep ants are good pollenators, but obviously have a very limited range
compared with bees and flying pollenators, but in the case of watermelon
which can pollenate itself I wouldve thought the ants wouldve done a better
job ... one melon, pfft! Anyway next summer ill get a paintbrush and get
kinky with the flowers
