Tidy up around ponds
Around ponds, remove the last of the dead foliage. You can still divide hardy waterlilies and cut back overgrown marginal plants.
Protect tender plants
Tender plants should already have been brought into a frost-free greenhouse until the risk of frost has passed.
Last chance to divide perennials
Lift and divide overgrown clumps of herbaceous perennials, or leave them until spring. Cover borderline hardy plants with fleece sacks to protect them from the worst of any winter weather, especially if still young.
Cut back grasses
Ornamental grasses and bamboos can be cut back and tidied up.
Take root cuttings
Root cuttings can be taken now and throughout winter. Papaver (perennial poppies), Verbascum (mullein) and Phlox are suitable examples.
