One of the things that I really love about living at TSH is the fact that we have four distinct seasons. There is a definite Spring, Summer, Autumn and Winter with all the wonderful variety and experiences they bring. It also means that we have a much shorter growing season than some of our more ‘tropical’ friends which of course necessitates a few changes in the way things are done.

And as evidence for these changing seasons this morning I awoke to the first frost of 2011. Admittedly it was a fairly light frost, but it does highlight the inevitable march towards the quiet of winter. It’s now time to begin making preparations for the cooler months such as ensuring that the under cover beds are ready to go, where they can take advantage of the warmer microclimate, as well as potting up any species which are likely to need some assistance over this period. The main species that comes to mind at the moment is my lemongrass clump.

This weekend we will begin preparations by redesigning the greenhouse, and setting up a few new watering systems under the verandah.

Every weekend I set myself a task to complete around TSH that keeps the vision moving in the right direction. Sometimes this task is large, such as fencing a new paddock, but at other times it can be quite small such as improving an existing system. This weekend, my task was to build a new vege garden using the wicking bed system.

A wicking bed is a marvellously efficient garden design in which you water from below. It is basically a giant self-watering pot in which you water via a filling tube. The water creates a reservoir under the soil of the bed, and the water then ‘wicks’ up to water the plants. The major advantage of the system is that there is no free water on the surface, so evaporation is minimal.

At TSH we have two beds, both located on the back verandah, which have been designated to be wicking beds. And this weekend I created one of the beds. The location of the beds was chosen so as to allow year round growing (it’s under the eaves so shouldn’t be too effected by frost) as well as to be close to the kitchen (virtually in zone 0, if you are permaculturally inclined). It should also help reduce the amount of reflected sunlight into the entertaining area during summer which should help make this area feel much more comfortable.

And let’s not forget… produce a mass of picking greens, herbs and other vegetables for the kitchen.

A video-essay of the building of this bed can be found on Green Phoenix Permaculture.

I’ll post an update in a few weeks around how it is going. Below are some time staged photos… click on them to zoom.

Wicking Bed (Week 1)

The Canberra region has quite a harsh climate for gardeners with very hot dry summers, and bitterly cold winters. As a result our growing season is quite short requiring strategies, such as greenhouse growing of early seedlings, to artificially increase the growing season.

Last night the realities of cool climate gardening became apparent as the first frost descended over the property. Admittadley it was still quite a light frost but it does symbolically, and practically, demonstrate that the joy of summer is over. The still of winter has begun…
