Dean a friend of mine advised me that sweetcorn will taste floury when grown out of season, when it is too cold something about them not ripening properly from the cold. I find if I grow corn during Autumn/Winter my corn stalk is stunted to under 1m and produces floury corn....YUK

Dean: did you plant seed or seedling? If the sweet corn was planted too near dent corn then a cross could have occured. How long between harvest and consumption? (sugar (sweet)starts turning to starch (flour) as soon as you harvest) What variety?

i live in cairns is it possible to keep the best cobs from my harvest to use the kernels for my future crops. if so what is the way of preparing and drying the kernels

Deano. Depends on the variety. If you bought heirloom / non hybrid seeds then yes. If you went to the supermarket/nursery and bought a packet of sweetcorn seeds then probably not. Also depends on how many varieties you planted and how far apart (including your neighbours). Corn is promiscuous, varieties will cross very easily.

Thanks David. Corn was grown from seedling. Planted 300mm apart and no neighbours had corn growing. The ears where picked and cooked straight away. Dont know what went wrong but will grow again when the seasons right. Thank's again.

I'm growing corn in Darwin for the first time, it started off going great guns but now is being eaten away by ants! I have eggplant planted next to it and it is doing really well, any ideas??

I've read that when sowing corn seeds, you should put two seeds in each hole then thinout when they shoot. Is this neccessary and, if so, what is the reason for doing it. I have also read this for other vegetables.

this is to get the strongest seedlings and therefor a better crop as well as to in sure a plant per hole. i do not thin out corn and instead plant in decomposing seed pots with a few extras. corn does not always do well in normal seed trays when trans plated

In Adelaide, around the inner suburbs, corn can be started as early as late june, if you put a frame around the seedlings and cover most of it with glad wrap, (put one inch holes around the bottom).
