My sweet corn has prolific growth of side-stalks emerging from the base of each plant. Is this normal, and should the additional stalks be removed to encourage growth and production from the main stalk?

We are trying to grow sweet corn in Coogee sydney. The plants are growing but the top 9 inches have turned to seed like things and lower down the stem there is feathery like fronds. Should I cut the seed like things off? Thanks in anticipation. Bren

Do NOT cut them off! That is where the pollen to fertilize the cobs comes from. The feathery bit or silks as they are known are there to receive the pollen. I hope this is not too late too save your corn.

Little black bugs. Very skinny, weaving in and around the kernels of my corn cobs. Does anyone have any ideas on what these are. About half the lengths of a typical kernel and half the thickness of the hairs on the corn. Thanks

when is it the best time to plant sweet corn

the question how to grow corn. Corn does not like too much water. If you grow pumpkin, plant corn with it. Neither of them like to be watered too much. Just a short watering by hand held hose in the mornings is usually all that is needed, but of course you must also mulch. Sugar cane is good for this

Hi, I planted sweet corn seedlings a week ago. The tips of the leaves are turning brown. Not sure why. Seedlings are in full sun and have been watered every day.

Hi It always depends on your climate and how much water your giving them, remember they don't like too much water. if your leaves are squishy they're being watered too much. if they're dry there not getting enough water.
