I want to stop cross pollination between Corn varietys but I read that to do this you need to grow the different varietys of corn at least 700ft apart.

Does anyone know if I could stop cross pollination by sowing the two Corn varietys a few weeks apart?

Yes, they need to be separated in space or time. Starting one variety a couple weeks later should be enough.

Another thing I read that helps is to plant a row of sunflowers between the sections of corn. Since the sunflowers are also tall, they work as a barrier.

I don't have the space to do the 700ft a part thing. So I do the time thing. I have mine separated by 3-4 weeks.

Separate the planting times by two to three weeks. They will mature at different times so you will have less chance of cross pollination.

thanks , I will grow my two different corn varieties (true gold and golden bantam) next to eachother and a few weeks apart to prevent cross pollenation this next season.

Are they Hybrids or Varieties. If they are Hybrids I don't see the point of keeping them from cross pollinating. Unless you are trying to keep the collor of the ears the same. I don't know enough about these two corns. Are they white vs yellow? Looking at the names makes me think they are both yellow's.

IF you are using time to seperate them. Make sure you factor in the DTM one may be earlier than the other.

Good luck

They are not Hybrids, they are both Traditional open pollinated Heirloom corn Varieties which are getting harder to find as sweeter low starch hybrids become more popular.

harvest time for True gold in 12 weeks and Golden bantam is 14 weeks.
