Probably the best thing to do is to buy heritage seeds that have been listed as originating in short season climates like Canada and the northern USA. They have a much shorter growing season. The other alternative is to wait until 2 or maybe 3 melons have formed and then cut all subsequent runners off to give the plant the most to put into those 2 or 3 melons. Trust this helps.

If you do not have access to cow manure, but nitrogen rich fertilizers or otherwise, pour a mixture of 2 water and 1 urine on the plan roots...it has worked for me for more than five years

Try ordering yellow watermelon seeds from Livingseeds. Their service is amazing: They stock a good selection of watermelon varieties.

Hi, You need to get your seeds from a repretable organinc supplier, the watermellon is a tropical plant so growing it in your airing cupboard is not a bad idea, a glasss house too should be benifitial in summer. the seeds need to be dried then planted in seed mix.once they have grown to planting size, grow them in good compost, I am trying to go over to a no did policy. My watermellons did no good last year. but as I said they are tropical fruit and grow better in Queensland and the N.T. than Vic,but a good summer helps
