What to do this month

  • This is the month to plant fruit trees, deciduous trees, roses and berries.
  • Remove broken or crossing branches from trees and shrubs.
  • Hydrangeas can still be cut back to two vigorous buds on green wood. This is important, as green wood is the flowering wood.
  • Check lawns for unwanted moss growth, as this is an indicator of poor drainage. Treat with an iron-based moss killer.
  • Leave all frost affected foliage on plants, as this will help to protect the rest of the plant for winter. Prune off in spring as new growth appears.
  • Mulch young tender plants and protect frost sensitive plants with frost cover, hessian etc.
  • Consider indoor plants to oxygenate our enclosed homes during winter.
  • Move house plants away from heaters and cut down on watering.
  • Continue to water lawns at least once a week and more often if dry.


  • Ensure vegetables do not dry out and keep weeds and pests under control. Protect all Brassicas (broccoli, cabbage, cauliflower, Brussels sprouts, kale) from white cabbage moth. A light dusting of vegetable dust every 3 to 4 weeks will do the trick.
