Winterproofing your Garden

Winterproofing your Garden

Summer is over and we had the first Autumn frost last night 26th September. It was only a light frost and we have some cloud cover for the next few nights so it won’t be as cold tonight. Still I set-too to protect some plants.

Winter Plant Protection

  • Tender plants can be protected in a frost free environment. Conservatory plants left out for some summer sunshine should be brought back inside. This is true of Citrus fruit trees and Pelagoniums.
  • Insulate your greenhouse with bubblewrap and install a heater for really cold nights. Aim for a minimum temperature of 37°
  • Lift tender rhizomes of Cannas and Gladioli corms.
  • Prepare hessian or sacking to wrap the centre of tender plants like Tree Ferns and Palms.
  • Reduce watering and keep pot plants a bit on the dryer side.
  • Mulch or cover the growing crowns of perennials with bracken, dry leaves or compost.

Winter Maintenance Tips

  • Put terracotta pots on feet or raise onto bricks so they do not freeze to the earth or paths. Bring in none frost proof pots.
  • Clean up paths, greenhouse glass, garden furniture, bird feeders etc.
  • Retie or stake trees that may suffer from wind rock.

Causes of Winter Damage

  • Prolonged excess damp can be fatal to pot plants. In winter there is little or no drying effect.
  • Snow can break the branches of trees and the weight can damage conifers and evergreens.
  • Frost will damage soft fleshy growth easier than it will kill ripe twiggy growth. Camillia growers will know what frost can do to blossom.
  • Climate changes, prolonged cold snaps, unseasonal spring or summer weather and other changes can create ‘plant stress’ that shortens the plants life.

Other tips – Leave on holiday for hotter climates and return in spring.

Single and Collerette Dahlias Tips

Single and Collerette Dahlias Tips

The hot subject for discussion this Autumn seems to be the renaissance of Dahlias. For me they have never been far from my garden but I understand how fashions come and go then return.

Quick Dahlia Cultivation Tips

  • Disbudding two out of three buds per stem with produce longer, stronger and more weather resistant stems.
  • Support all but the very low growing Dahlias with a stake or triangle of canes.
  • Keep feeding with high potash feeder until September.
  • Remove dead and dying flowers regularly.
  • Earwigs may be a problem for flowers destined for the house but otherwise they are good predators and should be tolerated.
  • Buy new tubers from a Dahlia nursery. A plastic bagged retail plant often disappoints and I have never known one flower better than the picture on the packaging.

Single and Collerette Dahlia Varieties

  • Single Dahlias bred from the dark leaved varieties like Bishop of series are popular this year.
  • The garden writer Rachel de Thame has had a pink variety name after her.
  • After Eight is the name of an AGM winner with  white flowers on very dark leaves.
  • Collerettes are flowers of two petal layers rather than one single – see pictures
  • One collerette that caught my eye was ‘Twyning’s Revel’ a 4-5′ high plant with salmon flowers, orange centre and dark fern foliage

Note
Dark leaved Bishop’s children Dahlias are looking very good as Autumn comes to an end. Children will be surprised the leaves are not green and the flowers remain so colourful read more
