Here in 6A, I'll be planting my Asian radishes in the middle of August. Been doing it for years and years.

I agree mid to late August for the Asian Daikon radishes. I start seeding my Cherry bell and French Breakfast about September 1 and plant more each week thru the end of September.

I will plant some later today and continue planting weekly till mid Oct. They are great sellers at farmers markets. I maybe a little early by starting now but I will take a chance on crop failure. If they do good, I will have them to sell.

not sure why FD says that they have trouble germinating in hot soil. Perhaps Michigan never reaches the broiling temperatures of the South, but daikon germinates fast and strong in early August in Michigan.

Germinates well here too in hot August in WV. You do have to water it well twice a day, but I do that for all my August sown seeds.

I wrote an app that will look at the weather forecast for your zipcode to see if the temps at planting and harvest will work for plants. You can put in different planting dates to see what works also.

If you use it, would appreciate a feedback about if the recommendations make sense...

It appears there was a bug in the weather tool - it is fixed now.
