Sweetcorn not Ripening

ColinAColinA Posts: 336

Hello

 

I have several sweetcorn plants on my allotment they are Mr Fothergills Incredible F1 variety.

They all have really large cobs on the plants but they are not turning yellow and have been like this for the last three weeks or so. I keep trying the seed inside but only a clear liquid comes out, has anybody come across this before

    When did you plant them? Have the tassels turned brown?

    The seed was planted directly into the soil in eaqly June and yes the tassles have turned very brown, Thats why i cannot understand why they have not ripened

    How many plants did you have? Did you plant them in a block or a line? It may be inadequate pollination, although unpollinated tassels tend to stay green. We have eaten all ours and cleared the land.  Try eating one?

    They were planted in a block as usual as I have grown them for many years. The cobs are very large and full but still no signs of turning yellow.

    On the seed packet they are shown yellow in colour

    I'd try cooking and eating a couple if I were you image

    I didn't grow any this year but last year I grew Rising Sun F1Hybrid - I've just found the empty seed packet - certainly when I picked and cooked them last year they were nothing like as yellow as the illustration on the packet, until they were cooked - but when the tassels were brown they were perfectly ripe. 

    I found this which may be of help http://www.examiner.com/article/gardening-101-when-is-sweet-corn-ripe-and-ready-to-pick

  • I planted out Marshalls bought small plants this year on my allotment, only 9 plants and they only grew to about 2ft high.  I only got about 4 cobs altogether.  Not very successful.  Any advice as I have never grown them before.

    Sweetcorn likes lots of water (although it likes the soil to be well-drained).  Even in last year's phenomonally wet summer on our free-draining sandy loam I had to have the sprinkler on our stand of sweetcorn quite frequently - I grew a block of 20 plants.

    This was a very dry year.  Did you water yours enough?  They need water to grow and even more water to produce cobs.

    It's worth persevering as the flavour of cobs cooked fresh from the garden is like nothing else image

    Allotment max- sweet corn are wind pollinated. They do best in a large block. I grew about 60 plants from 2 packets of seed,(Swift F1)started inside in individual pots, planted a foot apart in May in a 7 x 9 block. Even so the ones on one edge did not pollinate as well as the ones in the middle. Also as Dove says, they like a lot of water.

     I don't think 9 even if you planted  them 3 x 3 , is a big enough block.

     If youhave an allotment, grow a big block next year. You can't beat sweet corn that has been picked and boiled within an hour. surplus kernels can be frozen, although we ate all ours. August/September = sweet corn fest.
