I have experienced growing watermelons and whoever told you that when the closest leave dies the melon is ready is right. Also, they take about 5-6 months to grow if you want big, juicy watermelons.

I've been told that when the closest leaf dies the melon is ready to be picked. This is the same for all vine veggies and fruits. I have found that this 'rule' works

Remi, April is too late for melon and pumpkin in Melbourne. They need a long growing season (especially melon) and need starting in spring.

Hi, I live in Melbourne and it is early April and my family and I have started growing a vegie-patch and would like to know - is this the right time to start growing watermelon and pumkin?

Hi It's March and my kids planted some seeds early this year. The vine has been taking over since late Jan and now we have a watermelon which i think is nearly ready to be picked. it's been growing rapidly for a month or so and the growth has slowed down this last week. We only have 1 melon on the vine - is this normal for sydney?

It should sound "dull" when tapped, but I always think sound is subjective. Look at the growing end where the stalk is and about 5cm away will be a tendril (curly growth). When it starts to wither it's close - wait till it dies .and then pick and enjoy. (In your area it still could be a couple of weeks away.)

Amy, When to pick watermelons is one of life's great mysteries, but there are a few tips to help you out...Tapping on a ripe watermelon give a heavier thud than unripe ones, watch out for a yellowing stem, a yellowing patch on the underside where it touches the soil and also the skin gets a more powdery look to it rather than it's normal glossy sheen. I picked a couple before I started to get it right. Another thing is to leave it then for another wekk after you have picked it so that it can finish ripening. good luck
