Sometimes a caterpillar will eat off the base of the silks - making them look ripened. Will also eat the corn. Corn love Nitrogen, Zinc and water especially early. Beans grown up corn is good, but the beans don't put much nitrogen in until they die off.. I also grow cucumber/gherkins/lebanese cucumber under the corn. 3 crops in one.

I grew corn for the first time from seedlings. The cobs are now still very small but the silky threads have gone brown. So I pulled a cob off thinking it must be ripe, but there are only a few corn kernels on the cob. Have I left them too long? How do I know if they are ready for picking?? They've had plenty of water (we've had a wet spring in Brisbane!) Any ideas??

i only take the one main cob off the corn then pull the plant and compost it. any subsequent cobs are usually small and spindly, and in my opinion not worth the bother. cheers

traditionally corn has been used as a climbing post for peas as the peas put nitrogen back into the soil that the corn has taken out. My question is that corn and peas are opposite planting times so how does this work? Anyone?

beans not peas, they are a summer crop.

Perhaps growing climbing beans with corn would work?

i grew my first bunch of corn last season but was not very succesful i grew them from a punnet that i brought.... this year i will plant by seed would it be better to plant direct or sow in seed trays? :) x

i have found it best to plant your corn from seed the seedlings dont seem to like to be transplanted they are almost sertain to die.plus i always soak my seeds in tepid water overnight to encourige germination.

I found exactly the same - corn seedlings from the garden shop invariably die or do poorly. Much better to start from seed.

Corn don't transplant well. Direct sowing is much better.

do you remove the seeds off the cob to dry out or just leave them on the cob.
