I wasn't happy with MN midget, either. I'm sorry to say that because it seemed to grow okay for me. Others sometimes died!
I have stood in my melon patch and hoped my garden visitor would not notice dead melon plants. No, they didn't have to freeze. Our interminable cool, windy June weather would kill them!
Except, once I began to grow Passport galia melons, they have never failed. Tampering with success, and faced with fewer places to buy the seeds, Diplomat galia melon is what I've got this year.
Heart of Gold was once grown commercially around here. I think it should do well for you,
@Lavender2 . I never stopped at the roadside stand to buy one so I don't know what they were like. No one has grown melons commercially in this valley for decades, that I know about.
After I moved here, for many years, I was making regular trips thru the Oregon melon country. It's about 250 miles south. Their melons were on display in our markets - taunting me ... well cowboy, I'm no longer melon
less. So there!
