Hi Lizzy, do you mind me asking where your melons came from? I'm in Queanbeyan myself and have just moved to a place with garden space so my daughter would love to grow some yummy things, but it's too late to start melon from seeds and I can't find rockmelon seedlings!

My wife had a rock melon 2 weeks ago and I just threw the seeds and core under a small mango tree I'm growing and they germinated straight away. Although rockies are planted early in September here (seedlings) I'm going to give it a go. I might plant some corn near them, to give them some shade.

I live near Bundaberg in Qld. They use to grow a lot of rockies here years ago. They would start picking late Oct so probably planted seedlings in August (no frosts here). I worked on a farm during the picking season one year (late 1980's). When to pick the melons - they would start to turn from green to yellow and the melon would come away from the stalk/vine easily. They would fall off with a gentle tug. They seem to pick them a few days too early these days - they are green on the outside color and very firm flesh to eat. A melon ripened properly, will be softish and have a good melon smell.

They are ready to pick when the stem attaching them to the vine starts to die off. They sweeten further if you keep them at room temperature for a few days after pic,inf.

When rock melons are ripe you will see a small crack start to appear where the stalk joins the fruit. The stalk will come away easily from the fruit when you gently attempt to pick it.

My rockmelon is rotting on the vine. The underside is being attacked by a mould on fungus. I have tried rolling the fruit over to have sunlight on all sides but it does not help. Even fruit hanging off the ground on a trellis is being attacked. Is there a spray or dust I can use to stop this problem?

Any copper-based spray will work. As long as it is not applied excessively it is a safe spray to use. Rock melons are in the same family as pumpkins, zucchinis and cucumbers and are very susceptible to downy mildew and other fungal problems. To reduce the problem grow on trellises in a well ventilated spot. High humidity does not help the problem. Trust this helps.

For a non chemical method, which I've used for many years, make up a solution of powdered milk and water the whole plant with it. For some reason the milk seems to either kill or neutralise the powdery mildew

Rockmelons are sweet, but the flesh is too hard rather than juicy. Any suggestions as to how I can grow better ones next year?
