The bare trees and fallen leaves signify that the garden is moving into its annual resting period... but now is not the time for those green fingers to rest. Grab your coat and sharpened secateurs, there’s lots to do in the garden in June!
Garden tasks to take care of this month:

MUST dos this month!

  • June is the perfect time for planting trees, including fruit trees, as they go dormant during winter. Read more here about how to plant a tree.
  • In frost-prone areas provide protection to frost tender plants.
  • Add a thick layer of mulch around shrubs and trees to protect the roots.
  • Prune deciduous trees that need their canopies thinned and start pruning early variety fruit trees that have shaken off all their leaves at the end of the month. Do not prune trees that flower in spring e.g. Cape may (Spiraea cantoniensis) and Wild pear (Dombeya rotundifolia). Pruning stimulates new growth so do not prune tender plants in frost-prone areas.

General tasks

  • Keep raking fallen leaves and add them to the compost heap or use as a mulch.
  • Adjust watering to accommodate for the lower temperatures, but do ensure that you maintain a regular watering program.
  • Allow your lawn to grow longer before mowing, this will provide insulation for roots against the cold.
  • Add winter colour to your garden by planting hardy annuals like Primulas, Calendula, Stocks, Violas and Petunias; feed once a month with liquid fertiliser.
  • Feed, water and deadhead bedding plants and add a layer of mulch to protect them from winter’s cold.
  • Now is the time to take hardwood cuttings of shrubs and trees. Here’s how to do it!
  • Prune summer and autumn flowering plants like Ribbon bush, Barleria, Plumbago and Tecoma, and trim summer-flowering salvias in warm areas.
  • Pick sweet pea flowers every few days to encourage further growth and feed plants every two weeks with a granular fertilizer high in potassium.
  • Winter is also the time for hard-landscaping maintenance like fixing fences, paths and paving, or to sort out your potting shed.
  • Send your lawnmower in for an annual service and attend to gardening tools.
Now is the time to sharpen and oil your pruning equipment.

Rose care

  • Remove dead and diseased roses, and prepare holes for transplanting or planting new ones.

  • Prune overgrown herbs and compost.
  • Harvest peas two to three times a week to encourage flowering and pod production.
  • Stake fava beans and Brussel sprouts to provide extra support.

  • Sow oriental vegetables like Chinese cabbage, mizuna, pakchoi and tatsoi.
  • Prepare beds for permanent crops like asparagus, rhubarb, chives and artichokes.
  • Harvest Jerusalem artichokes now - lift with a fork to not damage the tubers.
