May – Permaculture Food Gardening in Subtropical Australia

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

We are in the middle of the subtropical autumn. The very first “cold-weather” greens and veggies are ready for harvest. Others are starting to compete with each other and with the self-seeded ones which are also trying to claim some space in the garden bed and around, and I love it! Food everywhere 😀 This happens when you allowed them to go into seeds last season. They are simply popping out everywhere and the only job you have is either harvesting or replanting to create more space in the overcrowded food forest community. Even dough we have autumn, it feels like spring with all the greens coming out of nowhere. What else can be done in May? Check the list below 🙂

General jobs in May

  • I tend to be too generous while sowing new seeds in the ground so thinning out the new growth might be necessary. I am usually harvesting the young greens, like bokchoy or radish, regularly and enjoy them as they come while making more room for the other ones
  • Watering freshly planted fruit trees and bushes if necessary. They need to strengthen up before the winter comes!
  • Weeding the garden beds if needed.
  • Applying compost tea + water mix (1:4), every 2-3 weeks onto the garden beds. Most of the winter vegetables like brassicas, garlic, beetroot, carrots, and so on need lots of nutrients to grow. Help them thrive. I have made a video about how to make and use compost tea. You will find it under the article.
  • Have you recently planted new fruit trees? If so, do some research to check if they can handle cold winds and temperatures around 0 degrees Celsius. Some trees are very vulnerable while young, especially when there is no other or only a little vegetation nearby. Some frost protection cloth might be necessary.

What NOT to do in May

  • Trimming bushes and trees should be considered carefully now. All established and overgrown evergreen trees and bushes may help the young ones to get through winter by blocking off the cold winds. The deciduous ones like Mulberry, Peach, Nectarine, Apple, Nashi Pear, and others need to be pruned as required which is usually about the time before they get new growth.
  • Leaving old leaves on the banana plants is also highly recommended to protect the trunks during winter.
  • Planting new tropical fruit trees and bushes is also a big NO in May as they most likely won’t get established before winter.

Sowing, planting, harvesting


  1. This is the monthly edition for that particular month. If you haven’t read my ‘autumn gardening jobs’ article yet, start there: Autumn – Permaculture Sustainable Food Gardening in Subtropical Australia
  2. There are more plants you can grow in the subtropical climate but I am limiting my list to the plants which I grow in my food forest and I have the best experience.
  3. If you are looking to buy some heirloom, non-gmo and open-pollinated healthy seeds or plants, consider visiting my online shop at
  4. I have included links to the individual seeds and plants I sell. Simply click on the name with the link and a new page will open where you can read more info about the plant, and you can buy it if you don’t have it yet (all coloured names include the links, more to come!). Enjoy!


Many of them are self-seeding in our food forest. 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 how to use them, along with some other tips and tricks.


No trees in this list, mostly because there are too many fruit trees you can grow in a subtropical climate so simply choose what you enjoy eating and what suits your garden. If you want to know what trees we are growing, check our ‘Food Forest Guide‘.


We are harvesting daily and as required, depending on what we like to eat and cook, and/or what needs to be harvested. The May harvest list includes and is based on what grows in our food forest and what is possible, including fruit from our trees. 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.
