Will direct seeded, fall planted seedlings survive the winter in Maine? The experiment continues. In October they looked very healthy even after experiencing some very cold weather. A couple of months later in mid-December they look, well, hard to say really. Definitely not dead and for a deciduous plant, actually fairly healthy.

As a reminder of what these looked like in late fall, here is a picture taken in October.
Another question which should be interesting to see the answer is whether the un-sprouted fall Seabuckthorn seeds are still viable and waiting for favorable spring weather.
Some of the literature makes a distinction between stratified and non-stratified recommendations for outdoor planting. Stratified seeds (seeds stored at 35-41 degrees Fahrenheit for 90 days) are recommended for outdoor planting in the Spring. Non-stratified seeds are recommended for fall planting. The seaberry seeds and seedlings here are planted from stratified seed and this is not the best practice from the literature. I'm not fearful of these failing - lesson learned. I also am confident they will do just fine. To date the literature's best practices have been only a guide since not every iteration of experiment has been documented.
