Nah, nothing I can really do for it at the moment. I laid some twigs there to kinda support things and diffuse any water flow, but the water would just wash back out if I tried to block it. And if it washed around whatever I used, it could just get a lot worse. I'll give it time to settle. So far, about 24 hours later, it's no worse.
Look into this painted mountain corn. Its a fast grower, the fastest ever at 85 days. It's also frost hardy, drought tolerant, and good at altitude. A supercorn that might be worth your time. I planted so early, most would consider it stupid. I still shouldn't plant corn for another month according to most guides, and I planted it three or four weeks ago!
