I have been gardening every year for most of my adult life, in Australia and Canada, and water has always been at the center of action. From filling buckets in Deadman’s Creek on my homestead in North Queensland, Australia, irrigating from rivers for cash crops nearby, and using well and rainwater here in the bush in Central Alberta, Canada.
I have used overhead sprinklers and trickle irrigation, progressing towards less water use without diminishing crop yield.
With drier and hotter weather in my neck of the wood at this time, I am currently moving into the use of wicking grow bags for my garden. That means supplying water to the bottom of plant roots, rather than from the top
The availability of modern, durable and cheap plastics has made this a practical proposition, in my case re-using 25 Kg chicken layer feed bags that soak up water when filled with soil and placed in a shallow bath.
Thus, the amount of water used to grow a tomato, for example, is reduced by an order of magnitude in comparison to trickle irrigation where water is wicked away from the row of vegetables by the adjacent dry soil.
Wherever there is a challenge, there is a solution. That is why we are able to snoop around on the planet Mars without even setting foot on the place.
