When do you know your rockmelons are ready to be picked

You can tell when to harvest rockmelons by either tugging slightly on the stem directly attached to the fruit, if it comes of the stem it is ready, some varieties this doesn’t work for. Alternately smell the fruit you should be able to smell a sweet aroma if the rock melon is ready. If you still can't decide look at the skin in most varieties if differs slightly from the unripened ones also check the seed packets for a rough guide as to how many weeks from harvest you will be able to start harvesting. Good luck, enjoy your rock melons.

Six months ago I created a No Dig garden and I haven't looked back Two months ago I planted Rockies and I am happy to report that I have fruit. Try the No Dig Garden method and I think you will be very pleased, with all your vegies. Organic and wonderful for you and the earth.

How disappointing to have lost the fruit and flowers! Could it be they're getting too much sun? Maybe give them some shade using a few pruned branches from a handy bush. Maybe try a higher dose of potassium to encourage flowering, such as a compost tea with banana skins. I hand pollinate my rockmelon flowers to ensure the little female flowers set fruit. Hope it recovers so you get some lovely rockmelon!

My vines came from seedlings that were planted around 7-8 weeks ago. I had some small (small gape size) fruits just starting, now they are gone. I live in Brisbane, plants get watered and fed regularly. Do they need to be covered or anything? There are no flowers left now, am I going to get fruit or should I pull them and start over? Thanks guys.

Rockmelons do not ripen after being picked. They just go soft. Do not pick until they go orange and smell sweet.

I still dont know which variety to plant in a country like Fiji. And i dont know why people over here are onlyconcentrating on sugarcane and stuff. Hardly anyone is concerned about these fruits

It seems a waste of vine to not be able to cook n eat it for rockies or watermelon. Any one know how to cook the vines and eat? Are they safe to eat?

I do also put all my scraps from my vegy/ fruits juices directly into the soil. That's back in Feb and now I have rock melon flowers starting everywhere and 2 weeks ago I have my first 5 fruits growing so fast. Its very easy but need a lot of water morning and evening. I'm close to Brisbane.

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.
