Planting up our berms with perennial plant guilds

4/7/2017

Permaculture is about growing plants together in beneficial combinations - where the characteristics of one plant benefit another, and vice versa. A simple idea is to ensure you have habitat for pollinating insects (e.g. lots of different flowering plants) so you can be sure there are lots of the right kinds of insects around to pollinate your fruit trees when they come into flower too. Another is to use ground covers that don't directly compete with your trees and shrubs, but instead act as a barrier to weeds and grasses especially, which can compete for nutrients in the same soil layer with establishing produce trees.

Earthworks continued - hand finishing the sunken beds

30/6/2017

A machine gets you only part of the way with earth works - the next step was to finish things off by hand...

The challenges of trying to make a bed completely level was also a very useful lesson to learn!

The earthworks have begun!

So, the house is a mess, there's soil pretty much everywhere, but we made huge leaps and bounds with our garden implementation this week!

Creating a design for our back garden

10/6/2017

With any garden overhaul there is a question about how much re-modelling should take place. At one end of the spectrum, new plants can be added around existing garden structures without fundamentally altering the original layout of a garden, at the other end, the whole site can be razed and re-contoured, shaped into something completely different to what has been before.

For our back garden, we have opted for something in between these two extremes: some existing structures remain, but there is a reasonable amount of earth working in the middle of the current lawn to make for better water flows and passive water capture.

Digging a mini swale to grow some bush tucker plants

2/6/2017

One of the challenges for our garden overhaul is how much of the original garden to keep the same, and how much to change. This post shows how we added in a water harvesting feature (a mini swale) within an existing landscaped area, to enable the establishment of new plants - some local bush tucker species!

The perils of pH: watch out for alkaline commercial soil mixes

21/4/2017

The pH of your soil is critical for good plant growth. When we buy in soil we expect it's suitable for growing plants in - but amazingly, this isn't always true. In fact, the issue of alkalinity of bought soil here in Canberra doesn't seem that uncommon - I've heard from several people of similar issues, so this post is relevant for anyone who's thinking of buying in some soil!

Growing perennial leeks in Canberra

7/4/2017

The leek we're all familiar with that you can readily buy in the shops is an annual plant, meaning that new seeds need to be grown every year to grow new leeks.

But did you know that leeks have a perennial cousin?

The perennial leek is a variant of allium ampeloprasum - the other being elephant garlic. I didn't know about it either, until I happened upon a market stall on the south coast, about 2 years ago, where someone was selling a few tiny leeks in a pot. So I bought the pot and took them back, and now, a few seasons on, it's taking off! From that tiny punnet, we now have a whole bed of them! What's more - they're delicious!

The challenge of gum trees

15/11/2016

A challenge to the would-be food gardener in the 'Bush Capital' is the amount of gum trees planted throughout Canberra as street and garden trees. Eucalypts are surprisingly water-hungry and pump huge amounts of water up from the soil to their leaves. Their light dappled shade allows more sunlight to reach the ground under the canopy, so that, unlike the heavy shade zones under deciduous trees in European and North American forests, where it's often quite damp, it's usually dry and crunchy under a gum tree. Combine this with the fact that gum trees produce chemicals to inhibit the growth of competing plants, you'll see that the hard, dry soil near to a gum isn't going to be a great habitat for your next planting of lettuce.

Making wicking beds from recycled apple crates

Some pictures of setting up some apple crate wicking beds in our front garden.

The indestructable Jerusalem artichoke

If ever there was a plant that can make you feel like you're the greatest gardener, it has to be the Jerusalem artichoke. Give them a little water, forget about them, and then after their cheery yellow blooms fall (they're a relative of the sunflower) and the plant dies down for winter, there's a secret haul of sweet knobbly tubers just below the surface.
