Have two different types Honeydew and Northern extra sweet (something like that). Can they be mixed. I would like to finish the honeydew ones off but there's not enough of them for the whole area. Thank you all for your very valuable time!!

This guide tells you all you need to know about which types can be grown together (well, not quite - I'll leave it to you to find out which category yours are in!  )

Both those varieties are F1 supersweets.
Would not be wise to mix them together or never should mix them with a hybrid or enhanced variety.

If you are not growing the blocks of plants almost side by side, then you maybe ok.
From what I have read on growing mixed varieties, the blocks of plants need to be a minimum of fifteen  feet apart.
I know the allotments near me put up a single panel of trellis between sweetcorn crops from neighbouring plots with added pea mesh when they are close by. They swear by this method for stopping any cross pollinating.

You could always grow them in stages, so one variety matures earlier for picking, so then you will reduce any cross pollination of them at the same time.
