We are certainly a long way north of Ardmore! I have a friend in OKC. Our plants and morels are 2 weeks different; fruit trees bloom 2 weeks early, morels pop 2 weeks early, yards need mowed 2 weeks earlier, etc. I would guess Ardmore is 3 weeks milder (if that makes sense). With that said our pond seldom freezes over completely and when it does it's no where close to 6in thick. 19 acres with a large basin that's 10ft deep. But, EVERYTHING basically says Florida genetics is a risky at best effort. Wish money grew on trees...
