I don't think sunflowers like the tropics, I think they need long days to reach full potential If you start them in March they are scrappy if it's too wet they are scrappy. In Sydney they grow huge every variety In the tropics they are scappy, a couple yellow varieties just reach 6ft I'm in Philippines autumn beauty in Sydney is brilliant but here it's scrappy. I'm experimenting year round with some 20 varieties. Helianthus tuberous would be ideal, I can't get it D Every sunflower l know will grow scrapyif planted in autumn, the flower is yuk But if you know of autumn varieties please inform me Cheers D

Plant after the wet season. Maybe it is your soil - have good draining soil. Try making a raised row or bed and plant in the top.
