How big should a watermelon vine be before watermelons grow please ?

depends on the cultivar - small watermelon types grow on small vines - it's
a matter of proportion to expected fruit size afaik. are you growing
full-size watermelon? if so, something is probably seriously wrong!! if it's
a small cultivar & the plant size is ok, probably a matter of fertilising
the flowers.

male flowers grow on a stalk, female flowers have a swelling beneath the
flower that eventually (hopefully) becomes a fruit when fertilised. in the
mornings, either use a small paintbrush to take pollen from the males & put
it in the females, or pull off male flowers & dip them in.

if you can't find any female flowers, try nipping out the tips of the vines
to help them come on (check again in a few days).

if your plants are supposed to be full-size & there is therefore something
wrong, you can try giving them a boost with liquid fertiliser (preferably
home-made ;-). potential problems might be anything - who knows? possibly
soil fertility or not enough water or bad drainage, but it might be anything
(including moody plants ;-) one big problem would be if your weather isn't
warm enough.

I planted about 7 small plants a few months ago. The vines are about
2m long now. They flower but that is all they do. The leaves on the
vines are only about 3 inches long.

Is there a site where they have images on how big the vine gets to
give me an idea on how much growing the plant has to do before I get
watermelons growing please.
