Last winter I thought I'd try my hand at hardwood cuttings. I stuck my cuttings in coarse sand, and left them outside over the winter. Much to my delight, many of the cuttings have leafed out, and appear to be doing well. The easy ones were forsythia, ninebark, viburnum, fothergilla, and sweet spire. I was unsuccessful with longbeard and spirea, but will try softwood cuttings later this Spring.
My question is; when is it appropriate to remove the hardwood cuttings from the sand, and pot them up individually?
The photo below shows how they were overwintered. As you can see, I'll have to empty the entire pot to access individual cuttings.
Thanks in advance!
