In particular Humulus Lupulus (ie. hops).
There is a nice and quite expansive vine which has recently flowered on the unkempt edge of some allotments I walk past - I shall be collecting some to dry later this week, but there is a strong risk that the council will get around to giving that area a severe haircut such that it may not be there next year.
Hence I was thinking to propagate a couple of plants; apparently this is usually done from cuttings, but I haven't found much about what time of year to do it, or care and feeding for the young plants.
Anyone have any ideas?
