Hey Jason, your corn sound fantastic! I had a bad time with corn this year - male flowers came out in a heat wave before the female tassels were out and massive winds blew pollen away. So yield was down, but still v yummy! I'm tempted to stick in another crop now - hopefully not too late in the year.

Having grown baby sweetcorn for the first time, the silks are red in colour at the moment can someone inform me when is the right time to pick baby corn, is it the same rule as normal corn? where the silks should be brown?

Baby corn is picked much earlier than normal corn. The silks should be just emerging ( aprrox 1 cm long) and still soft. I find that the silks just poking out can be ready that evening or the next day as they grow very fast.

Just seeking opinions on whether my current run of corn is 'normal'. Planted Sun & Snow corn the week before Christmas and it has gone completely nuts. The block seems to have topped out at 2.3mtrs in full tassel... but I have 3 to 4 extra tillers on each plant and they are producing tassels and silks completely independent to the centre stalk. 7 of them even have side tassels at the 2mtr marker. The cobs that are forming are averaging just over 20cm in length and between 6-7cm in width. I'm only new to growing and was completely wrapped when they took off. Is this a standard result or something alittle more special?

first time growing corn for me. Doing well but now I have heard that it's better to remove side shoots leaving only one main stalk? 4-5 cobs on each plant but plants are only 60cms high.

how long does it take to grow sweet corn?

I have grown my sweet corn fairly close together and thought I had done everything properly. Once again though I find that the kernels are well under developed....they are usually white and very, very small. I harvest them when the silk browns off as seems to be the rule but even then. I also have found that even watering every second day as we are only permitted in Canberra the leaves are still dying off. In fact the ones at the back of the crop nearest the galvanised iron fence are completely dead - anything to do with radiated heat? Thanks for comments.

Hi, I tried Digger's Club Golden Bantam corn this year and planted closer together than instructed in a raised metal bed. They did really well with good organic soil, compost and a bit of blood and bone and another biodynamic preparation (Kickalong fertilizer). Really healthy and the corn tasted fine. Not as nice as the sweeter corn varieties, a bit more starchy but still really good fresh from the garden.

Jenny, My experience has been one decent crop from a stalk however you may get side shoots that produce a weaker crop. Personally, i would look to pulling them out and preparing the soil for the next crop in the rotation

Hi, I have 5 corn stalks growing in which i have taken corn of each stalk. The corn is very nice to eat sweet as. Can someone please advise me once i have taken corn of the stalks does the corn continue to grow or do you only get that one lot, please advise as i would like to start pulling my corn out and growing something else that is in season if the corn will not continue to produce. Thanks heaps.
