This winter, I am propagating grapes, gooseberries, blueberries & sea buckthorn (seaberry). I put them in some a
compost mix I created in pots and then buried them with
wood chips all around them to protect them from the winter cold. I have also put some raspberry tips in the ground this fall.
I had good success with grapes & gooseberries last winter, so I am expecting success with these.
It is a wait and see with the blueberries & sea buckthorn as it is the first time trying these with hardwood cuttings.
It could be possible to take the cuttings late winter or early spring before the leaves/flowers come out.
The best is to experiment to see what plants root from cuttings at different times of year.
