I am coming to the end of my Corn harvest. I have noticed that the corn is now poker dotted with white & yellow corn. All of my corn is from the same seeds I just staggered the planting to have corn for longer. Also the caterpillars are more frequent as are the gaps in the corn. Are all these normal for end of season "problems"?

You probably have some bicolour seeds mixed in with your normal seeds. Caterpillers are probably due to more rain this time of year for breeding. Gaps in the corn kernels is from poor pollination, windy when pollination is happening. Pollination happens over 4-5 days, run your hand up the tassel then rub on the silks. Also plant more than one row at a time. (Or in a square)

You can grow most corns anywhere, just get the planting time right.

This is my 2nd season of growing corn, last season was very successful, this year - not so. I have planted them almost exactly in the same spot as last season. Was that the right thing to do or wrong. The other point is that we have had some pretty crazy summer temperatures, high 20's then low to mid teens. I fertilised the garden during the winter/early spring.

Better to plant in different spot. Corn is a big user of fertiliser and water. When preparing the soil add compost/manures if possible, Soils always need some fibre replacement each year. Then mark out your rows about 50-60cm apart, Scratch a furrow in the soil and run some fertiliser in the furrow - I use Bunnings rooster booster. Have the soil wet before starting, after planting give another watering. Don't water again for 3-4 days. Too wet seeds will rot. When plants are 45cm high run some more fert down each side of the plants and hill the soil up around the stalk. Corn pollinates for 5 days and you pick it approx 21 days later. I just picked 28 cobs last week. S

I am growing corn for the 1st time & I seem to be winning, except, I have noticed the soil around the bottom of the stems is falling away as they are growing bigger, and the roots are showing a little. Is this normal? I keep covering them up but worry I may damage the corn. It is strong and healthy and they were dug in deep 45cm when planted. I just want to know if this is normal & are they air roots?

I hill the soil up around the plant when they are about 30-40cm high. This gives them soil for the roots to grow in. I also run a little fertiliser beside the plant before hilling up.

Sweetcorn does look as though the roots are showing as it grows taller. They help to support the plant and are quite normal.
