Your corn looks to be too close together. Before they get to be six feet tall, they’ll need more root space. I would try to separate the seedlings a bit while they are small.

Also, radishes make lots of seeds. If you let a couple go, you’ll have more than you know what to do with. When my seed turned over, however, future generations weren’t as good at development nor did they taste quite as good as the first generation. When I had a balcony garden in Seattle, I was able to get three crops a summer out of radishes. So plant again now! The midsummer crop (#2) was the weakest, probably because of the heat.

Thanks for teaching me about the carrots hating stones and spinach hating the summer sun.
