Q.Planting periwinkle
I have a large, very steep, rising bank at the rear of my house on which I planted Periwinkle last spring. I now wish to fill in the gaps with further plants and have approximately 100 in pots ready for planting. Would it be OK to plant them now, as it is raining and still relatively mild, or should I really wait until the spring?
Actually, fall is a great time for planting. Just make sure to keep them watered while adjusting to their new surroundings and becoming established. To help protect the tender root system once the onset of cold weather arrives, you can always mulch around the plants too.
