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

Rockmelons may need hand pollination with a soft brush.

16 Feb 13, marilyn (Australia - temperate climate): We have an incredible crop of very large rockmelons - organic. Unfortunately, slatters & dung bettles got into 6 ripe ones followed by vinegar flies which rotted them. Because the ones nearby were going to be attacked I picked them. They are not quite ripe. Is there any method of ripening picked rock melon? At last we have 4 days of cooler weather so I can spray with natural oils & pyrethrum. I am reluctant to pick any more until I am sure they will ripen. Thanks

19 Jan 13, Keryn (Australia - temperate climate): I planted rockmelon plants approx 9 weeks ago. They have grown well, and plenty of flowers, but no fruit. Not many bees this year, so what do I do to "pollinate" the flowers?

02 Jan 13, Reg Offord (Australia - sub-tropical climate): Should i prune the runners on my rockmelons? I have 3 vines, one came up itself, (it is doing best), the other 2 i planted in compost, and because of the heat, i have now mulched with lucurne.

20 Dec 12, Bert (Australia - temperate climate): Rock melon as in other such plants like pumpkin can be identified by the swelling at the base. The male will have a (dont want to be rude) pistle I think it is called, protruding in the flower. With the female you can already see the fruit, just needs the male to get going.
