They are not compatible. They must be separated by space or time. See the attached link for more information.

Thank you for the information n2xjk. I guess I will plant by time as space is out of the question. Do you think two weeks would be enough time between planting? Thanks again. Cbad

Actually it depends on the variety of Mirai, Some are synergistics which don't require isolation. Only the SH2 varieties require isolation. There are curently 10 varieties of Mirai

Hi Farmerdill: I have mirai 301, serendipity and ambrosia (thought it was another mirai but must have ordered it by mistake. If you have any thoughts on these I would greatly appreciate it. Thanks again, Cbad

Cbadcali - trying to separate sowings of corn by 2 weeks using the calendar can be tricky with varying weather conditions. If you had ideal conditions (like consistent moisture and 85 degrees every day), 2 weeks would be enough. But if the first planting faces a few 60 and 70 degree days, it will slow down enough that a 2nd planing will catch right up. A better rule of thumb is to plant the next variety when the first one is about 6" tall.

Farmerdill - are you sure about that? Harrisseeds.com carries Mirai, and each Mirai listing says augmented supersweet.

The only one I have grown is 421W. It does not need isolation as I grow it with white Se like Silver Princess and synergistics like Celestial. Notice that the website does not contain the customary "isolation required" statement common to Sh2's. Notice also that they stress "Combining these 3 types of sweet corn give Mirai customers their truly unique, one-of-a-kind "Mirai Experience" of the best taste, flavor and texture available in sweet corn today".
