How to grow Japanese anemones
Like many rambling plants, these can be hard to get going. Buy a well-grown potted plant and keep it watered in its first growing season because these anemones can flag in dry conditions before they get established. Plants prefer fertile soil that holds moisture, because in their native country summers are wet and warm and winters dry and cold. Leave them to their own devices once planted because they dislike disturbance. To increase plants, lift offshoots from the main plant as they emerge in late spring. Pot them up in plastic pots of soil-based compost to keep roots cool. This is also the best time to restrict plants. They can set fluffy seeds, so deadhead in autumn.
