Topic: Yellowing leaves on sweetcorn

[mpdjulie]

I have 24 sweetcorn seedlings in toilet roll tubes in my unheated greenhouse.  They are 4 - 6 inches tall.  Over the last few days some of the outer leaves of some of them have started to yellow.  I don't over water them but I have no clue as to why the leaves are turning yellow.  Otherwide the plants look extremely healthy.

How long since you planted them? XX Jeannine

They might have used up all the nutrients in the compost.

Mine have done the same but they are outside in the ground and not covered.

Restricted roots?.... sweetcorn does not like beign potbound, really it should only be sown 3-4 weeks before planting out, and in my area (Oxford/Swindon) that means at the start of June or the very end of May if the ahead weathwer forecast looks OK... I'm not sowing mine until  the weekend for that reason....

Thanks for replies - I think that I'll plant out but cover them with fleece as best as I can.
