S = Plant undercover in seed trays T = Plant out (transplant) seedlings

  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 20°C and 32°C. (Show °F/in)
  • Space plants: 40 - 60 cm apart
  • Harvest in 10-16 weeks.
  • Compatible with (can grow beside): Sweetcorn, Sunflowers
  • Avoid growing close to: Potatoes
  • Leaves and flowers
  • Young melons

Start in small pots then transplant when no danger of frosts. Plant into a raised mound to provide good drainage and warmth. Provide plenty of water.

Ready to use when the fruit falls from the vine

In the United Kingdom start the seeds in a heated greenhouse with plenty of light.

Rockmelons may need hand pollination with a soft brush.

Culinary hints - cooking and eating Rockmelon

Cut in half and scoop out and discard the seeds.
Sprinkle with some ground ginger or serve plain.

I am planting Mango (Candy) Melon and they apear to be similar. What time of year to plant plz? Sub tropics around central Qld.

I managed to grow two rockmelon vines. The season is now coming to an end. Do you rip the vines out at the end of the season? Or leave them dormant until next year?

They are annual plants.

As my rockies are finishing now, what should I plant after them?

You can plant whatever you like. Just build your soil back up with some compost/manure/fertiliser before you plant again. Plant things you like to eat and easy to grow. They have a planting guide on this website for each month I think.

What is the best method to test ripeness of a rocky. Cheers

Old varieties use to start turning yellow and they came away from the vine easily. The new varieties don't. They will probably turn a bit of a different colour but if you press around the butt end of the melon it will go inwards like a sponge. Release it and it will come back out. Another clue is to keep a record of when you plant and be guided by the time from planting to maturity or about 45 days after the melon has grown to full size.

I've never had them in the garden, I've just chosen some seeds in a few weeks back and I'm now getting melons, probably a bit late but, see what happens When I test them in the shop, I look for one that is an orange to yellow colour and tap it gently if it (sounds hollow it is ripe)

There are many different kinds of melons in the world but the ones we call rock melons in Qld use to grow green and turn yellow when ripening. The new varieties the commercial growers grow are green and they stay green. They are grown to suit the supermarkets, size, transportability and shelf life. Very hard when to know when to pick them. A grower told me 85 days after planting he picks, that is in the spring. If you look on the web for melons you will find a site with 25 different kinds.

Hi , My Edens Gem melons have a few weeks more growing until harvest. Most of the leaves have yellowed and died. Will they still be ok to be harvested. Thanks
