Hi Got about 8-10 stalks of black chewey corn - been flowering for last week and have a few tassels also , however I was trying to manually pollinate them but when shake the flowers over a white pot don't seem to be any pollen just the small flower pieces fall off and lots lots small ants , also plants covered in small ants ? - some plants also have leaves dried up and crispy looking , they get watered daily had also plenty rain recently and they have been fed with organic pellets as well as compost . They also covered in mulch and have peanuts surrounding them .. Why no pollen and what to do if anything about the ants ? Thanks

Although I am by far not an expert, you can defiantly harvest 2 good ones. I have sweet corn and Wumpum with multiple good ears. I have seen 3 good ears (though not on mine) and I have even heard of numbers reaching to 4 but that may be a myth ;) As to how to obtain those numbers i am unsure!

Hi :-) personally I would call perth arid climate zone meaning a bit later. However I dont think it would hurt it to plant it in June/ July. So long is you won't get frost.

Hi. My corn looks healthy and has grown tassels producing plenty of pollen but no silk or ears have developed. Will they grow later and can I store pollen to pollinate if they do or is it all over ? Do you know what maybe causing this? Many thanks Richard
