You can grow rockies in the autumn. Probably don't taste as good as the spring ones. I had rockies in and harvested the last in Jan - the fruit left in the garden bed, their seeds were germinating with in a fortnight.

tip when they are ready eat them

The older varieties use to start turning yellow and they would pull away from the vine easy when ripening. And you could smell the rocky smell. Called slipping. The new varieties in the super markets don't do this so it is a bit of a guessing game. They have green skin and the flesh is tough. I grew some of the newer ones and around ripening time we had 5

Hi, when you say the fruit is ready when it falls from the vine, does that mean the withering of the plant where the melon is attached? Also, should the melons be lifted from the soil as they grow bigger by placing something like a piece of wood under them? Thank you

Do I need hand pollination if see quite a lot of bees in the flowers

Planted about 20 rock melon plants. Plenty of male flowers. So far only two female flowers.. hand pollinate both.. not successful.. Why are there so few female flowers? Is there deficiency of certain element in the soil? Regards, L Lim

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.

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