Do Japanese anemones give out seeds?
I have a large area of Japanese anemones, can I divide these ?
It is very easy to divide a clump of Japanese anemone. Since buds are already forming, I suggest dividing in early spring once growth starts. Since they spread by underground rhizomes, you may find a rogue plant a foot away from the others. This is easily dug out and replanted. If you do that now, you may sacrifice blooms this year but you'll have a head start on next year. If working on the main clump, use a spade to slice through the soil. Lift the plants and pull them apart with your hands. Replant immediately and water.
