Sanguisorba are fully hardy to -20C, which means you can plant them directly outside in pots or borders in spring and there is no need to protect them from frost.
— Soak the roots in water for 3-6 hours prior to planting.
— Plant directly into a clear, weed-free space in borders in spring. Alternatively, to avoid disturbance, you can pot them up into temporary pots to grow on for a few months first to plant out later in the season.
— Plant the roots so that they are fully submerged with the crown or buds just below the surface and any top growth or leaves exposed.
— Plant in borders with free-draining soil or containers in full sun or partial shade. If planting in containers, use multipurpose or soil-based compost.
— Space the plants 15-25cm apart
— Water-in after planting and keep hydrated when in growth in the first season.
— Cut back flower stems to 3cm above ground level in autumn.
