In the United Kingdom start the seeds in a heated greenhouse with plenty of light.

Rockmelons may need hand pollination with a soft brush.

Probably after the last chance of frosts. Start seeds 3-4 weeks before the last frost.

Rock melons like it hot so should do well in Goulburn. Start the plants early in Toilet paper cylinders ready for planting after the last frost. Plant the cylinder and all as the cylinder will rot. Seeds are generally readily available or look online at companies like - Green Harvest, Eden Seeds, Diggers, New Gippsland Seeds, etc. There are a number of shorter season varieties listed if you are worried. All the best.

I am growing the diggers rockmelon world variety in Queanbeyan on a northern bank The ones that came out were honeydew. They are small but very tasty. D'agen rockmelon also grow. Get them going early in a glasshouse or inside.

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.
