Yellowing sweetcorn

[Sanjo]

I have over twenty sweetcorn plants in the greenhouse, in rootrainers and they are tall and strong looking, but they are starting to go a little yellow so I am assuming they have exhausted the nutrients in the compost?
I will not be able to plant them out for the next couple of weeks (last frost due end of April) and I have a tall strong cloche and added fleece to cover them with when I do. Should I, in the meantime, give them a weak feed of something, if so what would you advise please.

If you have the space after you plant them out?.......

You could try 'three sisters' technique - planting Corn with runner beans and squash?

Thanks Two Sheds, didn't think if that although I knew the benefits in the garden. Oh what a treat they have in store for them later today.

I've tried that in the past GF but not very successfully as I have limited space. I did try it two sisters ie sweetcorn and cucumbers last year and had some results but I had to grow the cucumbers up canes and a couple of times, up the sweetcorn itself.

Yeh a few sites recommend growing beans ( and other plants) actually up stems of corn too

But the three sisters were originally grown by Native Americans, and it wasn't sweetcorn it was maize which is a far taller and stronger plant. Their beans were also grown for drying. Doesn't work so well over here.

a little yellow is nothing to worry about .... if you really really really want to feed them, just do what two sheds said ....
