Tiny Sweetcorn ?!

   This is my first year growing sweetcorn. They seemed to get off to a flying start in modules, but ever since ive planted them out they havent been as happy. First they went quite yellow, however a quick feed soon perked them up and they returned to a lush green. My problem with them now is that they seemed to have 'bolted'. My whole block of sweetcorn have got male flowers appearing at the top and if you look closely you can see small cobs appearing. 'Why is that a problem?' I hear you ask. Well, the problem is that they only come up to my knee!

    When i think of sweetcorn i think of fields full of plants that are taller than me (at 5ft 2 thats not hard) not plants that are as high as my knee! I can only put this down to the dry spring and summer so far this year. My plot doesnt have a water supply so they probably haven't had as much water as they would have liked. Does anyone know if this is normal for the flowers to appear while they are so short still? Will they keep gaining height? Even if i end up with small little cobs of sweetcorn i'll still be happy. I cant wait to taste how sweet sweetcorn should really be instead of the bland stuff you buy in the shops.
