Sweet corn failure

[Jimmy]

Sowed them in pots in greenhouse.
Planted out when risk of frost passed.
They have been doing well, large healthy plants.
I was smug in the knowledge that such strong plants should give me many plump cobs.
But when I look closley there are no cobs.

Anyone know why?

Have the plants developed tassels and silks?

If the plants our exposed to cold temps then the tassels can form to soon so the pollenation of the silks is poor. Can you post any pictures?

Cobs won't appear until after the tassles have sprouted out of the top of your plants... be patient!

[Jimmy]

Will be patient.
But the nights are closing in.
I have some climbing french and runner beans about to come to fruition.
But worried a cold snap might get them ( and the corn ).

What variety are these,they seem quite slow to mature? Are those brown patches on the stems a bit of rot inside the stem,I hope not,but just wondering? Keep an eye on it? Have you fed them a high nitrogen feed? Some nutrients will give them some help.

I will try and recover the packet which I used as a label!

Wilko incredible f1
There are tassles formining on the top.
But none have any cobs to pollinate!

Dont forget we have the sizzling baking hot weather of September to come yet.

[Jungle Jane]

That's good news & normal,the silks will come soon & you'll have cobs.

How do i know when the cobs are ready for harvesting?
I have 4 plants that my brother in law gave me. They have a few cobs but one of them is quite big and plump. I have never grown corn so would be glad of advice.

When the silks turn have turned completely brown,dead looking,you can peel back the leaf & pierce a piece of corn,if the liquid is milky it's ready,if the liquids clear like water,it's not ready.

I just checked mine,noticed yesterday they looked ready. Outside silks are completely brown,peeled back mine & the corn liquid was milky but difficult to show in a photo. Eating it now.

I've grown sweetcorn for the first time, I planted swift. They haven't done very well at all. I think soil may have been the problem. My mini cobs on the other hand are doing great!!
I'll upload a picture for all you to laugh at tomorrow.

I tried Swift and Lark last year and though they were both crap, the Lark were much more vigorous than the Swift. So this year I grew only Lark, started them earlier, and planted them in the tunnel. I now have nice looking plants with plenty of cobs - just waiting for the silks to die off so I can try one!
