So I finally got round to checking my seed tins this morning.

I have got half packets of 2 sweetcorn types left: sundance F1 (which I believe is a normal sugar type) and Sweet Nugget F1 which I believe is an extra sweet type.

I know there are some groups of sweetcorn you can't mix but I can't find this information anywhere - does anyone know if I can grow these 2 types together? It would just be annoying to have to buy more and waste these seeds

I just grow one type - seems the safest and easiest option to work out...

Pip pip,

Hmm... Looks like I probably have one from each group - typical! Will have to buy more seeds...

don't know if i done it right but i grew sweet nugget and rising sun side by side last year and there wasn't any problems.

i did find that both varieties cropped at roughly the same time though so will prob just stick to one variety when the seeds are used up

Might be a blessing in disguise - other peoples' experiences may differ, but I've not found that the F1 sweetcorn varieties I've tried (including Sundance, but also Swift) germinate very well the second year, although it's not usually much of an issue because the packets I buy usually only contain around 35 seeds, which is more or less the maximum number I've got room for anyway.

Sow at different times, so they are not pollinating at the same time?

Unlike JayG's experience, my sweet corn seeds have germinated well even after four years; but as said, others may find it not so. As for sowing at diferent times, could be an idea to try but later sowings can often catch up with earlier ones. What suits me is to grow them in the greenhouse bed as well as outside and, if you have two varieties, they shouldn't cross-pollinate as last year, my GH ones cropped much earlier than the outside ones.

Oh for a greenhouse....

Although to be fair I wouldn't be able to get to the plot often enough to stop everything drying out and overheating! Maybe one day when I work a job that is nearer or with better hours!
