  • 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 in same bed): Sweetcorn, Sunflowers

  • 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.

"Pick on the Slip" -They will slip off the bush, so where the vine connects to the fruit it will break. you can sometimes see the stem connections starting to shrink. but if you lift up the fruit and it falls off its ready.

Our rockmelons came up by themselves and we will be picking soon. How long will a rockmelon last when picked?

Could it be powdery mildew? If so spray with 50/50 milk and water once a week

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.
