I planted some watermelon seeds about 6 months age and they are still not ripe. Green inside. They are still attached to the vine and the attachment is still green. The bottom is a pale slightly yellow. The crop has yielded around 100 melons and a mediun sized one weights 14 kgs. I have no option but to leave them growing till the vine falls off. Is this a good solution Regards Matt

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
