Can you grow rockmelon seeds in a big patch of soil like other plants? Because I have to grow seeds at school I have my own patch of soil where plants have preversly grow in

My new garden is smothered by vines of self germinating rockmelons from the compost bin. Had a tree removed and then enriched the soil with compost for the tomatoes -they are now competing with the rockies. With the unusually hot summer here in Tumut plus some generous seasol they are going gangbusters. Pity my wife doesn't like them .. so our neighbours and I will enjoy them.

If I waited until it is ripe, ant/bird ate before I harvested it. I tried once to harvest before it is ripe, the melon tasted very plain, not sweet. So, how do I prevent bird or ants eat the rock melons before I harvest?

I find placing fake snakes and frogs in your garden help... just move it around the garden every now and then....

I have grown Rockmelons in Brisbane ,and had about 10 but there are still a few flowers on the vine but no more rockmelons appear to be growing .When do I actually pull up the vines as there appears to be nothing happening except small yellow flowers, do they all come at once or in waves?

My dad used to grow a fruit on a vine that we put sugar on to eat. Had a flowery texture and a very thin cream skin and was oval in shape and seeds in middle. We called them cubes (not sure if this is correct spelling). I can't find anything on them anywhere, so any help would be appreciated as it is needed to settle a dispute.

Denise, I think what you are describing could be Indian Cream Cobra Melon. If so, seeds are available online from Eden Seeds.

Hi Sue, just starting my rockmelons now. How long did it take to germinate them?

Between 7 to 12 days dependant of the heat and amount of water they get.
