Growing Sweetcorn varieties together – do’s and dont’s

Just a note about growing different types of Sweetcorn together.

Firstly you need to plant them in a block if possible few lines wide each way rather than 2 or 3 long lines to aid pollination.. you get better pollination when they are together as the pollen is distributed by wind..

You basically get 3 types of sweetcorn.
Hybrid Sweets = abbreviated as su
Supersweets = abbreviated as sh2
Sugar Enhanced = abbreviated as se

You can’t just plant any of them together or you will get mutations of types and really strange cobs..

So basically I have been doing research on it and done the following easy reference – I also now understand it!!

Supersweets (sh2) must only be grown on their own or 2 or 3 other sh2 types..
Hybrid Sweets (su) and Sugar Enhanced (se) can be mixed with each other no problem.

If you have (like me) different types on the same plot they say they should be at least 50′ apart… a bit difficult sometimes!!

The types are sometimes noted on the seed descriptions but if not try to google them to find out what they are.

I have been asked about Baby Corn… Answer – No problem. Baby corn you can plant with anything as you pull it before it pollinates, but if you miss some they will cross with other corns. I would also cut the tassels off the mini corn so no pollen might stray to other normal sweetcorn.

Hope this makes sense and helps.  GJC

Moved to the UK from Zimbabwe in 2001. We had a 12 acre plot with a 2 acre normal garden, loads of Koi ponds, a 2 acre veg garden, 3 orchid sheds with over 400 plants, bonsai shed, granny cottage and workshop area.. Comming to the UK and into a 3 bed semi was a shock!! But we knew what to expect and just got on with our lives. I love growing veg and started to grow on my flat garage roof for a few years then moved on to a couple of garden shares then onto a full sized allotment at the end of 2011. I have done loads of work with it and got it looking good. see my blog site at Hope I can help others with info on growing and getting ground and allotments to their liking.
