Overview
- Latest checklists call for planting spring bulbs so they can root before winter, with one guide noting daffodils and crocuses now and some advice to delay tulips.
- Gardeners are told to prepare for early frosts by moving or insulating containers, creating warmer microclimates near walls, and mulching beds to protect roots.
- Final mowing is tied to temperature, with experts advising a last cut before growth stops near 10°C while raising the mower height and following the one‑third rule.
- Wildlife support features prominently, including leaving some seedheads, adding high‑energy bird food, and creating bug hotels, hedgehog shelters, or a small ice‑free pond.
- End‑of‑September jobs reinforce October prep: lift and divide overcrowded perennials, lift and dry tender bulbs for frost‑free storage, take cuttings of tender plants, and harvest, dry and label seeds for next year.
