Wouldn't be able to confirm with out a photo but it's probably paddy melon. It's a weed and it grows through out Australia and California. The fruit and foliage are toxic due to it containing cucurbitacin (so stop eating it). It's been responsible for a lot of live stock deaths through out australia. But if you want to grow it for ornamental reason it will positively grow from seeds. Be warned but, it is extremely invasive and will easily take over your garden. It's only real use for humans has been as an emetic. Have fun haha Happy days

I'm growing champagne watermelons, with the fruit now at the size of a baseball, but the leaves are starting to wilt and as its a sandy area and the ground seems to stay wet, I'm wondering if it's to wet.

Hi Shaz Good to hear about your watermelons. I did the same thing last year. However, they grew upto a size of a tennis ball and then went yellow and died. This happened to atleast 5 to 6 watermelons. Then i gave up. Can you please advise me what different did you do different? Do watermelon plants require support (above from ground). My plants and melons were on the ground. Thanks Ahmad

Hello Ahmad, I was reading through some questions when I came cross yours. I've been having this issue on and off for years now, involving cucumbers. They all are great healthy looking vines but what I have noticed is there is NO BEES! Cucumber, pumpkin, watermelons, mangoes, tomatoes and the list just goes on. What you will find is because on the lack of bees your flowers aren't getting pollinated you either need to invest in a few hives or start pollinating by hand. Try one vine by hand and let me know how you go

I am after seeds of a large round melon with a dark and lighter green skin. With dark yellow to orange flesh. We called them the Champagne Melon. My father grew these when we were very young. I haven't seen these in years only the pale yellow variety. Where would I be able to purchase seeds of these melons and maybe a photo to see if they are the ones. Thank you Gwen

Hi Gwen, we were given Watermelon Champagne seeds as part of a gift of a whole bunch of different seeds for our new vege gardens from my sister in law. They were all from Eden Seeds, located in Qld - www.EdenSeeds.com.au and they are non hybrid, old traditional, open pollinated varieties.

Old dried out cow poo has probably lost a lot of it's nutrient value, leached out with gravity and rain etc. Any manures need to be made into a compost material asap to retain as much of the nutrient as possible. Or you dig it into your soil over 6-12 weeks and with air water and turning it, it breaks down into the soil. The greatest benefit of organic material put back into the soil is it makes the soil loose and friable, which means it then drains well.
