Start in small pots then transplant when no danger of frosts. Plant into a raised mound to provide good drainage and warmth. Provide plenty of water.

Ready to use when the fruit falls from the vine

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

Rockmelons may need hand pollination with a soft brush.

Hi, we purchased a few rockmelon seedlings which were planted into the ground 2 months ago, they have grown wonderfully. The vines that is, there are little yellow flowers, but no fruit has started to show. Are we doing something wrong, do we need to trigger fruit by feeding the plant something special? Thanks, Simon

What type of soil is best for rockmelons
02 Apr 09, Sharon (Australia - temperate climate)
We have a rockmelon plant that has come up through the compost when I mixed it in the vege patch. We have 2 softball size fruit and at least 8 more growing. Wondering how long it takes for them to mature and is it too late in the season for them to be productive? We live on the NSW south coast. Thanks Sharon

do rockmelons come from flower buds??
18 Nov 09, adam synnott (Australia - cool/mountain climate)
Liv, yes rockmelons are from the curcurbit family, and need to be pollinated like a pumpkin of zucchini. They have male and female flowers, and I find it easier to pollinate by hand. The females have a small ball thingy on the base of the flower,(obviously, this is a small rockie, waiting to happen), and i take a male flower and press it into the flower of the female. The pollen is more potent when damp, so the early morning is a good time to do this. Often rockies have a small flower hidden under something, and I hand pollinate to make sure I get some rockies, otherwise, it's hit and miss. I'm in Armidale in NSW, and often the weather just isn't warm enough to ripen rockies and watermelon, but with a shadehouse or hothouse, I should get some this year. Good Luck.

Sir I am from South Africa and thinking of planting watermelon in a shadehouse. Is there any spesific type you will recomment and do you take them off the ground like tomatoes with strings or leave them on the ground? Thanks Ivan van Zyl
