Wood frame with some kind of mesh or house reo. Have as trellis or flat base.

I'm in Perth metropolitan. End January I planted seeds from a melon I had eaten, in a large pot of mixed potting mix. Seeds now germinated into healthy seedlings about 12cm high, some showing tendrils. I'd like to plant the seedlings out in the garden. How must I prepare for planting seedlings in garden, please? How deep to plant, distance between seedlings, what soil preparation needed. What fertilisers needed. How much watering? The garden space I have gets sun about half the day. Perth is quite hot so March will continue at temps. about 27-31deg. C. I look forward to your informed advice. Sincerely Margaret

Generally if you are planting seeds from seasonal crops that you are eating, like melons you are planting too late.You can use this website to work out when to plants crops for your climate zone. You indicate you are sub tropical when you are more likely temperate zone. By the planting calendar here you should have planted seeds in Sept/Oct. You should have prepared your soil over the previous 4-6 weeks, digging it over and adding compost, manures and some fertiliser. Plant every 3/4m and have rows 1.5m apart. Sow normal depth. Water every day, even twice a day when hot. Put some mulch/grass clipping around the plant, about 60-80cm diameter. Plants need a lot of sun, the more the better. Half a days sun may not be enough. Any general fertiliser is good for most crops. There is a lot of information on the internet about gardening.

how to hand pollination rock melon flowers and which flower has to be treated to start fruit to grow
12 Jan 21, Liz (Australia - arid climate)
Hand pollination for melons with the male flower starts with carefully removing a male flower from the plant. Strip away the petals so that the stamen is left. Carefully insert the stamen into an open female flower and gently tap the stamen on the stigma (the sticky knob). Try to evenly coat the stigma with pollen. (From www.gardeningknowhow.com/edible/fruits/melons/hand-pollinating-melons.htm) Female flowers have a tiny melon shaped bump behind the flower.

I threw a rotten rock melon outside. And now I've noticed plants coming up. I've got radishes growing where they are, is that ok. I live in the Adelaide hills.

Should be ok.

Hand Pollination, how is this done? (Gardenate - check some of the comments for pumpkin or zucchini. there are ideas for hand pollination)

Hi, My French friend says he has not had rockmelons as tasty as he had back in France. He is in the food industry. Do they generally grow a different variety there and if so, is that variety available to grow (or perhaps buy) in Australia? We live in Sydney. He is such a nice guy that I would love to surprise him with a solution - perhaps some seeds of that variety. Thank you, Regards, Ian

Go to a seed selling website Eden, Boondie, Seed Collection etc and ask him which if any look like the ones he had in France.
