Top ten autumn gardening tips from Gary Long, Head Gardener at Trewithen

  1. Clear up fallen leaves - especially from lawns, ponds and flower beds, add to compost heap or put in black bags, leave for 12 months to make leaf mould (excellent for adding nutrients as a mulch).
  2. Raise containers onto pot feet to prevent water logging or if possible bring into un-heated greenhouse/conservatory.
  3. Plant bulbs for a spring display next year, you will be rewarded next year with the extra burst of colour.
  4. Prune roses to prevent wind-rock, ideally to a third of their height even if still in flower (use the flowers in the house/give to your wife!)
  5. Plant out winter bedding if soil isn’t too wet.
  6. Insulate outdoor containers from frost - bubble wrap works well, fleece or again if possible move pots to a frost free area or greenhouse.
  7. Put out bird food to encourage winter birds into the garden.
  8. Trim deciduous hedges such as beech. The juvenile foliage will turn brown and remain on the hedge all winter creating a good screen.
  9. Raise the height of your lawn mower, grass will be growing slower.
  10. Use a seasonal bonfire - where this is allowed - to dispose of excess debris unfit for composting.

  • Self-drive visit to Bonython, Helston and Cross Common Nursery, The Lizard

    At Moyclare, planting began in 1927 by Moira and Louis Reid. Meandering paths lead through woodland shrubberies, herbaceous borders and sunny corners. The pond and lawns are surrounded by camellias, rhododendrons, mature trees, shrubs and many rare treasures from the Southern Hemisphere.

    Penmilder is a 2.5-acre south-facing garden with delightful bluebell woods and an apple orchard, which is particularly pretty with primroses and daffodils in the spring. 

    Sisters, Adrienne and Trish, are developing South Bosent with wildlife in mind. It comprises several themed gardens, woodland plantings, large mixed borders and a four-acre meadow. Other features include a mini-lake, waterfall and rill on the terrace, and several plant collections, all designed to provide year-round interest. Along with thousands of planted bulbs throughout the garden, a bluebell wood runs alongside the stream pathway.

    A booking form for this self-drive visit will be available in March 2021.
