Preparing Your Garden for Winter


Gardening does not stop in winter due to the fact that Johannesburg experiences fairly mild winters. In fact, your preparation ensures that your garden is established, cared for, and healthy and ready to burst when the temperatures eventually turn.

During this preparation season you should:

Tidy up your garden

  • Rake up unwanted leaves and make a compost heap, or mulch your garden beds to create a warm winter blanket.
  • Remove leaves that have fallen into the crowns of plants to prevent rotting of the crown, which my kill your plants. The likes of Clivia and Agapanthus could be affected.
  • Lightly prune out of shape plants. Do not cut back heavily as you may leave your plants exposed to the winter cold.
