I haven’t had much luck growing daffodils, which used to seem so easy. I live at about 1000′ altitude in the rain shadow of Lake Placid, an iffy zone 4; glacial lake bottom sand & rocks. The only really sunny part of my yard is along the street (Main Street of a hamlet and a major state highway) subject to sand, salt, and picking (can’t fault the residents of the assisted living retirement home too much). One place I tried planting them I realized was subject to waterlogging & freezing in March! My best results have been with planting worn-out potted bulbs after Easter, rather than purchased bare bulbs; does this suggest that the potful of medium they came in provides a little oasis in the sand?
My house is being renovated, and eventually the yard will be re-graded for drainage etc, so I hope as soon as this fall I can try again.
