I live in hoppers crossing vic and have raised veggie beds in my front yard. I have several rockmelon plants laiden with quite large fruit. I never expected them to grow this well considering the location I am in, is this unusual?

I have 4 rockmelon plants in my terracotta pot out on the balcony and they are growing really well. I have 3 small rockmelons growing on them (they are still green). I actually got these seeds from the rockmelons from the supermarket out of the half rockmelon I purchased. I took them out of the rocky & dried the seeds out and replanted them. Voila..... I have my own plants growing. Our season here in Victoria has been all over the place. But I am pleased to say that I finally have rockmelons going on my balcony in a bigish terracotta pot.

We planted, bought seedlings about 8 to 10 weeks ago. The vines are growing well and have lots of little yellow flowers, but no sign of any melons forming as yet. We have other veggies in that the bees seem to like but haven't seen any on the rock melon flowers at all. Do we need to hand pollenate them?

I planted rock melons and water melons in a tank. The plants germinated and appeared to be growing well and flowering. However the tiny rock melons turned yellow and dropped off when about 1 cm long. Do you think there is a soil deficiency?

Barbara, The same happened with my pumpkins in Broken Hill, until I was told that it is a pollination problem. Bees do not want to live in Broken Hill. We have to hand pollinate the dear pumpkins. Lots of info about how to on the internet. Nafisa

what do rockmelon leaves look like .i got a plant growing .iknow i have put rockmelon seeds in the garden ,but never seen rockmelon grow from scratch

Perhaps you could try starting out the seeds in pots with good quality potting mix. As a rule I always sow 3 times as many seeds as I need for my own use. You get to pick out the strongest for yourself; some may fail, and you can give others away whilst comparing ideas with other local gardeners. Hope this helps.

How do I know when a rock melon is ready to harvest
06 Dec 11, Ian (Australia - sub-tropical climate)
Rockmelon are ready for harvest when the stem begins to brown and appears to be separating where it attaches to the melon. I carefully lift the melon and try to gently rotate the stem, it will come away easily when ready.After harvest I leave them outside 2-3 days in mild sun to ripen. Then into the fridge.Hope this helps.

When the plant first starts sending out runners there is mainly male flowers. Then there will be female flowers, It takes a lot of visits from bees to pollinate and set the fruit. I hand pollinated pumpkin the other week and one female flower set fruit and the other didn't. The answer I have no idea. Pumpkins, cues melons are all in the same family. The pumpkin female flower only opens for about 6-9 hrs for one day. Probably melons cues zucchinis are the same. If you are in the sub-tropics you probably should have planted these 2 mths earlier. My rockies (I should have planted a month earlier) are about 5-10 days from start picking and some grubs are just destroying the leaves.
