A good windbreak can make all the difference – for your house, for your garden, for being outside comfortably. It’s important to protect natural windbreaks and integrate new ones in the design of your property and garden – different types in various places. In my permaculture garden I have designed edible windbreaks, and at my parent’s place, their windbreak is the natural tea tree foreshore reserve. Both have great habitat value for native species and the people living there.

The picture above is part of the natural windbreak between my parent’s house and the Gippsland Lakes. It is essential during the gale force winds often coming off the Bass Strait. Sometimes standing down on this beach you really have to lean into the wind to stop from being blown over. In many parts of the island people cleared the foreshore to get the views, but this not only destroys the ecological value, it destabilises the coastline and it makes living next to the water much more difficult with the winds and salt spray. You can even have an edible garden behind a windbreak like this.
The regular uprights of the trunks of the young tea trees (Melaleuca spp) in the foreshore reserve, and the multiple layers, break the wind rapidly, and even with just a thickness in some places of 10-15 metres a huge difference can be felt. Even if it is really blowing down at the beach, back up near the house and orchard, it is calm.

It also means that the people with houses along the water do not own the waterfront. There complete access for anyone to walk along and enjoy. (Image: Morag Gamble) |

| The coastline is retreating on this part of the island. I’ve been coming here for about 40 years and I estimate there has been at least a 2 metre erosion of the coast, more on Harrington Point – which is no longer visible here as a point. The foreshore reserve trees are also critical in holding the sandy soils together, but also as they die back and fall to collect sand on the wavy days. The washed up seaweed also acts as a buffer and sand collector. Where the trees have been cleared they have had to build rock/concrete walls. (Image: Morag Gamble) |
I planted up windbreaks early in the development of my home in subtropical Queensland to protect my house and main garden particularly from the strong south westerlies – the storm winds. I focussed on natives from the local landcare nursery such as lilly pillies and grey myrtle – not highly flammable, dense leaves and evergreen. They are now 3-4 metres tall and quite bushy. They deflect the winds wonderfully, but are located to allow the more gentle breezes to flow through this living space.

| The dense foliage of the lilly pillies and grey myrtles provide great western shade in the afternoon as well as filter the strong storm winds. From my observations at the Island, lots of uprights help a lot, as well as dense small foliage. The shape of the windbreak scoops the wind up and over the house. |
The bonus too is that the lilly pilly (Syzygium spp) fruit is edible and the grey myrtle/cinnamon myrtle (Backhousia myrlifolia) leaves make a lovely tea.

| The Grey Myrtle has lovely foliage – dense green with slightly red new growth. These new leaves are my favourite parts to harvest for teas and flavouring in soups and curries (a kind of nutmeg, cinnamon aroma) |

My windbreak also shades our house in the afternoon making the hot summers more tolerable on the verandah. This is important to me, because it means we can use this outdoor space – our main living room and homeschool classroom for most of the day. I love the windbreak too because these trees are full of a diversity of birds, and just sitting outside while I work, I am surrounded by birdlife and birdsong.
I usually plant temporary in-garden windbreaks to help new vegetable gardens areas become established. I often use Canna edulis or lemongrass because they grow quickly and are easy to manage and remove later. As well as wind protection, these plants also provide afternoon shade for young vegetables and other perennials. Once the perennial kitchen garden system is up and running, I phase out the extent of the canna and lemongrass, move it elsewhere, mulch it, eat it ….

More information is coming soon about the windbreaks at my place on my Our Permaculture Life youtube channel. I am making a short information clip to upload.
I use it at the edge of a perennial vegetable garden system – usually on the western side to provide afternoon shade. I use it's growth to add biomass to my compost, to feed the chickens. I use it as chop and drop mulch. I add it to the under layers of a no-dig garden. I eat it…. It doesn't get much of a chance to get away in my garden. I always use Canna edulis though – this is the only edible one (QLD Arrowroot). It has a more clumping growth patterns than the other cannas.
Morag what do you think about using Arrowroot as a windbreak? We have it growing here and it is spreading like wildfire.
Keen to hear more about wind breaks, yesss … thankyou
Thanks so much for this post. I am in a new area, living in what will be my last home, with a few undeveloped acres and free license to do whatever I like with the gardens. A deciduous windbreak is one of the items I need to plan and progress with so the more ideas I have the better.
Yes that is the same one we have. We bought it from Green Harvest. Hubby's birds love it but the chooks don't seem to eat it. I read it was good for the compost. I need to cook it and see what it tastes like as apparently it can be used instead of potatoes.
I was taking a gander at some of your posts on this site and I consider this site is truly informational! Keep setting up..
