When will my watermelon vine grow a watermelon? It is 2m in length and has small yellow flowers, but no fruit

A few months ago I planted two watermelons in my garden from seedlings. One has barely grown at all, the other has gone absolutely berserk and is at least 2 metres long and has 5 or 6 different 'arms' on it. A few yellow flowers have appeared recently, but no actual fruit to speak of. When (if?) will it grow an actual watermelon? Thank you

You have to wait for night temperatures to reach at least 50 degrees before the watermelon plant will start to produce female flowers, which is a tiny watermelon with yellow flowers just like the male flowers you probably have noticed on your plants. Once this occurs, it will not be long before the female flowers are pollinated by the male flowers, however depending on the variety of your watermelon, the fruit may not be harvestable for up to two months.
Reply:if you live in a very worm place have very good fertilize soil and vary moister not dry water melons need a Lot's water and heater and son should have fruit in 3Mont's.
Reply:the average time for the watermelons ive grown is 90 - 110 days. You still need to wait a month and maybe a half more. If your not sure if the watermelon is ripe, dont pick it. Wait. Ive done that to many times where i get so excited, yet the watermelon isn' t even ripe. You can even wait for the vine to die. Then your gaurenteed ripe watermelons, but make shure the fruits dont rot or even start to soften.
