Plantain lily 'Elegans' in November: monthly care

Hosta sieboldiana 'Elegans' requires very little pruning in the traditional sense. The main task is tidying up spent foliage rather than shaping or controlling growth. In October or November, after the first frosts have blackened the leaves, cut back all the foliage to ground level. Use clean, sharp secateurs or garden shears. Remove every leaf stem cleanly at the base, leaving no stubs that might harbour slugs or disease over winter. This autumn clear-up prevents fungal problems and keeps the border tidy through the dormant months. If you prefer, you can leave the frosted foliage in place until late winter to provide some shelter for beneficial insects and a bit of winter structure, then cut it back in February before new shoots emerge. However, most gardeners find October or November tidier and easier, as the leaves collapse into a soggy mass if left too long. During the growing season, remove individual damaged or slug-eaten leaves at any time by cutting them off at the base. This improves appearance and reduces hiding places for pests. After the white flower spikes fade in summer, you can cut the spent stems down to the foliage mound if you find them unsightly, though this is purely cosmetic. Some gardeners leave them for a more naturalistic look. Hostas do not need deadheading to prolong flowering, and they never require shaping, thinning or rejuvenation pruning. Mature clumps can be left undisturbed for years. If the centre becomes congested or flowering declines after five years or more, lift and divide the clump in spring rather than pruning it.
