Autumn is a fantastic season in the garden. The air is crisp, with warm long days, perfect for the tasks that need doing following the heat of summer. Autumn is a great time for sowing a new lawn, planting trees and shrubs, and of course planting the vegetable garden for the months ahead.


Autumn to do list

  • Autumn is the perfect time for lawn TLC, and to sow a new lawn. Check out our 4 simple steps of lawn care.
  • Harvest seeds from last season's crops for use next season. Label them carefully before storing.
  • Plant up pots and containers with autumn potted colour.
  • Apply Seasol plant tonic every 2-4 weeks to help prevent transplant shock, promote strong growth and keep your garden thriving.

In the vegetable garden

  • Replace the lost nutrients from those heavy growing seasons by adding in compost, blood and bone, and sheep pellets.  This will provide a healthy new foundation for your autumn and winter crops.
  • Keep mounding up celery and leeks.
  • Harvest pumpkins and dry well before storing.
  • Main crop potatoes should be ready for lifting.
  • Autumn is an ideal time to plant broccoli, cauliflower, cabbage, beetroot, spinach and Chinese cabbages.
  • Plant lettuce early autumn and you can get a good harvest from most lettuce varieties.
  • Sow seeds for your winter crops like carrots, swedes, turnips and radish. A good seed raising mix that is light and free draining will ensure your seeds get the best possible start.
  • Autumn is a busy season for slugs and snails so protect your young vegetable seedlings with Quash.
  • Aphids and whitefly will be about. Spray with Tui Insect Control for Fruit & Veges to control.
  • If early frosts are a concern, protect seedlings with a cloche or growing tunnel.
  • If you choose to rest some areas of your vegetable garden over autumn and winter, planting a green manure crop like lupin or mustard seed adds nitrogen rich organic matter back into the soil. For more information see our Cover Crops Guide.

In the fruit garden

  • Autumn is a busy time for the home orchardist as new season fruit trees make their way to the garden centre and existing trees are laden with fruit.
  • Fertilise citrus trees in early autumn with Tui Citrus Food, unless there is threat of frost.
  • Prepare new planting sites with compost and plant into garden mix.
  • Protect grape vines with bird netting.

In the flower garden

  • Autumn in the flower garden signals a time to change to new season's potted colour.
  • Pansies, violas, and polyanthus are more tolerant of the cooler weather.
  • Plant into Tui Flower Mix for best results and feed with Novatec.
  • It is the best time to plant bulbs for spring flowering, see our Bulb Growing Guide for more information.
  • Basic maintenance in the flower garden requires pruning back flowering plants that have finished for the season.
  • Support taller flowering plants like dahlias and sweet peas with frames or stakes.
  • Mulch your flower beds to suppress weeds and protect plants from the cooler months ahead.
  • Control aphids, whitefly and scale with Tui Insect Control for Flowers.
