Autumn gardening: Benefits of preserving perennials and using ornamental kale

Gardening practices during the transition from summer to autumn significantly impact local biodiversity. Experts advise against the immediate pruning of perennials and the removal of fallen leaves, as a prematurely cleaned garden can become a sterile environment for birds and beneficial insects.

Leaving seed heads and hollow stems intact provides essential food sources and winter habitats for various species, including solitary bees, ladybugs, and butterfly pupae. Specific plants recommended for late-season preservation include Echinacea purpurea, Rudbeckia, Sedum spectabile, Echinops, Verbascum, and Achillea.

For those looking to replace faded summer flowers in containers, ornamental kale and cabbage are suggested alternatives to chrysanthemums. Unlike many summer blooms, ornamental kale thrives in cold weather, with its purple, pink, and cream hues becoming more intense following the first frosts. These plants require well-draining soil and consistent moisture to prevent root rot while surviving the autumn chill.
