All my sweet corn cobs are the same as this photo. They are sort of dividing into 2, kernels also are nor forming well. I think viruses, but maybe something else ? [/img]

Lack of pollination surely?

There’s definitely lack of pollination but no idea why the ends are misshapen

odd shape might be due to empty spaces with a few kernels between them lack of pollination explains the empty spaces

i wonder if it might be to do with excess wet - causing splitting. Has it been unusually wet where you live? the rainy weather would also contribute to lack of pollination, as sweetcorn depends on wind to scatter the pollen. saying that I would ask if any other of your veg has been effected, could be dodgy compost if so

These were block planted in the soil, having been started in the greenhouse in pots with bought in compost.

I did wonder about the compost. As I know that if there was any residual weedkiller or other chemicals from the green waste, it can cause distortion in stems.

Cannot remember variety, but they grow 6ft tall, and all of them only have only 1 cob on them.

Watering has not been a problem, as no hosepipe bans this year.

I can understand duds due to lack of pollination.

We will see if the problem re-occurs, as I have another later batch (by 1 month) growing of the same variety. They are just sheding pollen, so hopefully might be ripe before the frosts.

This year has been a bad year for other vegetables. I've already pulled out my 10 varieties of tomatoes, due to having watery, pulpy, tasteless fruit. The only varieties worth it were Alsia craig and Chocolate, but I threw thwm away as well.

Leeks, Butternut Sqash (blossom end rot), Cucumber (blossom end rot) and Broad Beans (flower drop) terrible

Cauliflowers (no cabbage whites) and Runner beans are looking good.

Early potatoes in ground were terrible, but in tubs they were fantastic.

Blimey that's proper late, good luck with them you never know with the climate being what it is

With all of the blossom end rot symptoms, you likely have had inconsistent or extreme soil moisture conditions

it could be a planting timing issue I guess - re pollination - I sowed 2 packets of seeds, in pots in gh and then planted them out. I had too many plants so cleared an new area and planted some more then gave the rest to my neighbour. The first bed was wonderful, fat cobs and second and third smaller cobs. But the plants I put out later in the newly cleared area had gaps in the cobs and no second cobs. my neighbour had the same issue. So plants sown at the same time but just planted out later did a lot worse.

I can rarely grow sweetcorn outside. We are in the south of England, and field crops seem to do all right, but our microclimate isn't conducive to things that need warmth. I can only really grow tomatoes successfully in the greenhouse too.

Mine is only just at this point. Then I noticed that the maize around us was taller, but behind in terms of development. THEN I remembered that most of the maize crop is taken as wholecrop silage for cattle feed. Oops!

Just gathered the 2nd crop of sweet corn, and cleared the ground.

These were a lot better, no distortion of the cobs, and 50% were well filled cobs. But 50% were still only half filled.

And only one cob per 6ft plant.

Certainly not worth the effort. So I must change the variety for next year.

I just like eating the cobs fresh, the same as picking fresh Raspberries and eating them straight away. The flavours and sweetness are out of this world.

Very true, can’t beat fresh sweetcorn

I have given up with sweetcorn as it doesn't do very well for me. We were fortunate that we managed to buy a few really fresh sweetcorn cobs this year. Microwaved in their sheaths they were beautiful.
