Hello am sorta new here but decided to just jump right in. I am a firm believer that it never hurts to ask questions. I was born & raised on a small farm in southern Minnesota. My mother grew a beautiful row of peonies without any seeming difficulty. I was transplanted to new Mexico about 35 yes ago. I have been trying (unsuccessfully) to grow them here. I have planted them in full sun in soil that has been mixed with good potting soil. We get up to 2 to 3 ft of snow at times. And the temp falls below freezing most winter nights Nov - April. I provide adequate water & fertilizer. The peony plant itself dies down to below ground and starts to come up in April. The altitude here is a little over 6000 ft. And yes I have found out the hard way that this slows down plant growth a lot. I am certainly open to suggestions and advice. So please If anyone knows the secrets I would be most grateful.
