if you take cuttings now, use a bit of rooting hormone and put them in pots in the greenhouse to protect them from the wind. remember, the cheap aldis blackcurrent bushes come at a price, the new varieties of blackcurrent are much more resistent to leaf mold than before, the cheap aldis ones are invariably not the new type. ask if you can exchange or help your neighbour prune their blackcurrent bushes and increase the number of varieties in your garden. Black currents, gooseberries and red currents should be pruned every 3 years, so plant them in threes and prune one of them every year
the above method is a superb way of generating lots of plants, a good idea for someone intending on planting a hedge row
