Growing Watermelon

Water melons must have been invented for rank amateurs. I live in Coconut Grove, Darwin, NT and have zero gardening experience, but decided to plant some water melon seeds (in pots) at the end of October - build up time to our summer wet season. They germinated fast so out into the garden they went with a lot less ground preparation than there could have been. They grew, started producing flowers (male only for quite some time) so I kept watering them with the odd bit of general purpose soluble plant food. I haven't seen any diseases so they haven't been sprayed - apart from the termite man's overspray with he did my house's annual ant and spider treatment. Then, in early December, growth went up a few notches; I could see how far a vine had grown in a day. They started taking over the garden. Flowers appeared everywhere, as did tiny native bees to attend to pollination. Every few days a small watermelon appeared and quickly got bigger. At that point I sought some advice from a local garden shop on what I should be doing; they told me to keep watering and sold me some organic fertilizer pellets to feed them with. Now they've taken over the garden, have started climbing fences and keep on producing new melons. I'd never have imagined it could be that easy.

Hi Grahame, can you tell me what type of seeds you used please where they from a packet or out of a fresh melon? Thanks

I have never been able to grow them. I really don't have the ground to do it. Watermelons like virgin soil. There is a lot of difference between a plant growing well and producing a good end crop. I have rock melons growing - huge - some would weigh 3-4 kg. First one I picked, tasteless - probably too much watering. Have cut back the watering. Over watering when the fruit has grown it's full size can make the melons split. Hope it keeps going well for you.

Climate must be a big factor with water melons, Mike. We'll never get an overnight low of less than 24C in summer, and rarely get one under 18C in what we call winter, so I'm going to try growing them all year round. Evidently Darwin soils are very poor because nutrients get leached from them by the heavy rain during the wet season so I'm learning how to counter that. Having never been a gardener, the water melon experience has spurred me into action and today I'll be planting some papaya and guavas. I don't think the traditional favourites like plums and peaches can be grown up here but I'm looking into it. I do remember a particular plum from my childhood (50+ years ago!) called a greengage; they were green when ripe, and sweet. Has anyone on here ever grown them?

They grow water melons here - Bundaberg - in the spring. Winter 10 to 24 degrees with some nights down to 3-4-5. Spring time it is warming to 16 to 30 and summer 20-24 to 30-34. Seedlings are started late winter and transplanted in Sept. They pick them from late Nov and can extend into Jan. We can buy them on the side of the road - 2 for $5 - weigh from 2-3 kgs to 8-10 kgs.
