Garden diary

Published: 2016-05-24


  • Raise vegetable beds as the weather cools and the rain arrives, so you can plant a wider range of vegetables.
  • Plant seedlings of cabbage, cauliflower, broccoli, winter lettuce, spinach and silverbeet.
  • Sow seeds of pea, onion and lettuce.
  • Plant pots with pansies, polyanthus and primulas for winter colour.
  • Prune hydrangeas. Apply garden lime to improve pink colours and aluminium sulphate for blue.
  • Slow down watering of house plants and move them away from draughts.



  • In warmer areas, sowing of many vegetable crops can begin in July. If the soil is too heavy and wet, sow in seed trays for planting out later. Keep building up vegetable beds with compost.
  • Plant seedlings of artichoke, cauliflower, lettuce, onions, potatoes, rhubarb, silverbeet and cabbage. To allow earlier plantings to germinate in cooler districts, protect seedlings with an empty 2-litre soft drink bottle with the neck cut off.
  • Sow seeds of broccoli, cabbage, broad beans, cauliflower, peas, lettuce, onions, radish, spinach, silverbeet, swede and turnips. In warmer districts sow carrots, parsnips and beetroot.
  • In the flower garden, prune or plant roses, and prune hydrangeas and fuchsias.



  • Plant seedlings of cabbage, cauliflower, lettuce, broccoli, silverbeet and spinach. Lay seed potatoes in a tray in a sunny place for 7-10 days until the ‘eyes’ sprout, then plant.
  • Cabbage, celery, spring onion, onions, silverbeet, spinach and lettuce seeds can be sown in trays for transplanting later.
  • Divide up the perennial herbs and plant out as the soil warms. Lift and divide clumps of rhubarb.
  • Prepare the garden for spring planting, digging in generous amounts of compost.
  • Plant new season flowering annuals in containers.
