What are the yellow beetles eating the flowers on my Rockies , I thought they were lady beetles but the are longer and only eat the petals , I hope they are pollinating at the same time.

To stop the melon from rotting on the ground, lift the melon place 2 bricks on the ground under the melon , rest a piece of arc mesh on the bricks ( about 12 inch square, place a little dry grass on the arc mesh and lower the melon on to the dry grass. This will allow the air to keep the melon dry.

What type of fertiliser do I need to help the rockmelon plant produce flowers

Hi, Im in Adelaide and I'm just wondering if I can grow rockmelon all year round so I can have a constant supply. Cheers, Jan.

Hi Jan, I live in Adelaide as well and starting with the rockmelons now. Did you have any success so far?

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

Why can't you grow rock melons with potatoes?

When I Was a child during the 1940 you did get a rockmelon much larger and more tasty then these hybrids you get today but ok they were not good for marketing due to there poor shelf life but do you still get it some were in the world today.Would like more information on it and were can you still get seed?

When rock melons are ripe you will see a small crack start to appear where the stalk joins the fruit. The stalk will come away easily from the fruit when you gently attempt to pick it.
