I have about 20 fruit growing at various stages on the one plant but all of a sudden the leaves are going spotty then brown and dying.any suggestions

rockmelon plants grow well, lots of male flowers, occasional female flower, these go to about marble size, yellow and drop off. maybe not pollinated?

Sounds like not pollinated - cross pollinate them by hand.

I finally have fruit growing ! 4 plants, planted seedlings Oct, Nov. In a sandy soil with some fresh compost mix. The turning points? Big rainfalls in late December encouraged plant growth, recently started picking of runners as female flowers weren't taking, then bam over a week later about half a dozen fruit took off, aiming to get 2 dozen at least.

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!

Im kinda new to gardening. I have done it on and off but always on learning curve. I will try what you sugested and see how it goes. I appreciate you replying.

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.

I only thing I would suggest is not enough water. As melons are very high in water they need a good constant supply to fill out. Mulching the roots will help conserve water. All the best for next season.
