Glasshouse & indoor

  • To help ripening of crops remove shading as light levels fall
  • Plant prepared hyacinth bulbs for Christmas in pots
  • Reduce watering of Hippeastrum (amaryllis) to give the bulbs a resting period
  • Continue harvesting tomatoes, peppers and aubergines

Ponds and water features

  • Thin out oxygenating plants. Leave on side of the pond to allow wildlife to crawl back
  • Where possible cover the pond with netting to prevent leaves falling in and rotting in the water.
  • Continue removing blanket weed and duckweed
Seasonal jobs for the month: October

1. Plant up containers for winter display using winter flowering pansies, violas and polyanthus, add interest with evergreen shrubs and perennials such as Skimmia, Euonymus, Heuchera and Carex.
2. Finish planting of onion sets early in the month and plant garlic for overwintering.
3. Cultivate heavy soils before it gets too wet and leave to break down over winter.
4. Plant up containers with winter bedding such as pansies, violas and polyanthus, evergreens such as ivy and Brachyglottis greyi, and spring bulbs.
5. Rake up and dispose of fallen rose leaves to limit the spread of foliage diseases.
6. If cleaning or repairing of pond is needed, autumn is the least damaging time for this. The main breeding season is over, but amphibians are not yet hibernating.

Lawn

  • To establish new lawns sow seed or lay turf
  • Apply autumn law treatments with moss killers or proprietary moss killers
  • Apply biological control (nematodes) against leather jackets and chafer grubs in lawns
  • Consider planting bulbs such as C. tommasinianus, Chionodoxa luciliae, Narcissus 'February Gold' and Scilla siberica for naturalising in lawn

Kitchen garden

  • Plant out spring cabbage
  • Plant onion sets suitable for overwintering
  • Continue harvesting apples and pears
  • For best choice order bare root fruit trees and bushes early
  • Continue picking autumn raspberries and blackberries
  • Reduce damage to ripening marrows, pumpkins and squashes by placing the fruit on wooden boards or tiles

Ornamental garden

  • Plant new and divide well established clumps of hardy perennials
  • Clear gone over summer bedding and prepare ground for winter bedding/spring bulbs
  • Stop feeding hardy garden plants
  • Plant spring flowering bulbs in borders and containers
  • Move evergreen shrubs

Pest and diseases

  • Remove fruit affected with brown rot
  • Bright orange, raised spots (pustules) on leaves of leeks and chives are caused by leek rust
  • Keep leeks protected with enviromesh or fleece against leaf mining fly and leek moth.
  • Do not compost blight affected foliage and tubers of potatoes and tomato plants and fruit
  • Clumps of honey coloured toadstools at the base of trees and shrubs may indicate honey fungus
