December in the Garden- Permaculture Food Gardening in Subtropical Australia

by Ewa Bekiesch, Permaculture designer, educator, sustainable living consultant, and healthy food advocate.

Summer is here! Hot and humid days are going to be our companions for the next three months or so with more or less rain however, this doesn’t stop us from producing healthy and delicious food! There is no “food-growing brake” in a self-sufficient homestead. Firstly because we love naturally grown food without any additives, and secondly because there are many different foods that are happily growing during this time of the year.

This article might give you some ideas about what can be done, sown, planted, and harvested in the garden in December in subtropical parts of Australia. Note: this is all based on my experience and our work in the food forest. Feel free to comment below if you would like to add or ask something.

Since I am being asked where to get the plants I grow – we do sell many of our food forest plants and seeds online through our website here. You will also find the link below at the end of this article.

For easy-to-grow vegetables in hot summer, check my video below at the end of this article or in my YouTube channel.

General gardening jobs

  • Applying compost tea every 3-4 weeks to plants with new growth and the garden beds with growing veggies. I know, this is something I write about each month but it is really important! Check my video here if you want to know how to make your own. You can use any greens for it! Applying compost tea to your garden should be a regular task if you do serious gardening and you want to see a good crop.
  • Sowing, planting, harvesting – check the list below.
  • Weeding and mulching! Mulch will keep the soil cool and moist; this is exactly what we want. The earthworms are most happy and active when the soil temperature does not go over 24°C
  • Apply fruit fly bags and nettings on ripening fruit and veggies, make or buy fruit fly traps, and plant heat-resistant herbs like Bush basil, Rosmarine, mint, shallots, and other near fruit trees and garden beds to confuse the creatures you don’t want in your crop.

What NOT to do this month

  • Planting any brassicas and radishes is over now until autumn. They don’t like the humidity and hot temperatures we are coming into. All of them will bold quickly and all sorts of bugs will have a feast on them, too, so forget it! However, if you have some of them bolting now, you can leave them for the beneficial insects and for seeds for the next season

Sowing, planting, harvesting


Many of the plants are self-seeding in our food forest and emerging like out of nowhere. If you don’t know some of the plants in the list below, check my ‘Food Forest Guide’ for more info about the plants, how to grow and use them, along with some other tips and tricks.

We are harvesting daily and as required, depending on what we like to eat and cook, and/or what needs to be harvested. The August harvest list includes and is based on what grows in our food forest and what is possible, fruit included. As you may think, we don’t harvest all of it every day. Many of them simply keep growing and wait patiently for their turn to end up in the kitchen, as green mulch ‘chop and drop’, some of them go to compost if they are taking over, or as food for our chickens, ducks, or worm farm. The possibilities are endless.
