Water restrictions have become a part of everyday life in many parts of our country. Even with restrictions in place reduced rainfall over many years and increased urban sprawl are causing water storages to fall. How will gardeners, particularly those intent on growing their own food, respond to these difficult circumstances?
For me, the answer is not replacing my green, leafy garden and vegetables with desert plants! When buying new plants, sure I look for those that are able to thrive with less water. But many fruits and vegetables require regular watering and I don't want to lose many of the existing non-food plants in our garden. Therefore, I need to find ways to keep the water up to my garden and make the most of the water that I can use.
There are several things we are doing. We've just switched the diverters on our gray water back to the backyard. Lengths of black pipe take the water from our washing machine and laundry trough to the back yard. The bath/shower is now plumbed to take water to the front lawn. Having diverters in place means that we can flip the valve to allow the water to flow into the sewers if we don't need it, such as those weeks in winter when we were getting regular rainfall.
In addition to the gray water pipes, I have a bucket in the kitchen sink and one in the laundry trough. Since we had our new solar hot water system installed, it does take longer for hot water to reach the taps. The buckets catch the cold, clean water and that goes straight onto vegetables and herbs. Then I return the buckets and catch the slightly soapy water from rinsing the dishes. (The laundry one catches hand-washing water). This water goes onto non-food plants that can tolerate a little soap.
Warm, leftover water in our drinking flasks gets emptied into indoor or outdoor potted plants. Water in saucepans that has been used to cook vegetables, rice and pasta is also used on pots and/or vegetables when cooled.
And last but not least, my husband has obtained a 2000 litre water tank which is soon to be installed. Lets hope we get a few good rainfalls to fill it. We will still keep the rain barrels to catch water from the shed and carport.
Once you have thought of all the possible water savings that can be made, how can you make sure that precious harvest isn't wasted? Adding organic matter to the soil and mulching will help retain water. Thinking about plant placement may also be helpful. Some plants are more hardy and may be able to shade more delicate plants in the heat of the day, allowing them to receive the gentler morning or late afternoon sun. Look at what is around your plants- are light surfaces like shed walls throwing reflected heat onto your plants? Could you grow a tough, quick growing plant like nastursiums over the wall? Plants respire, giving off water from their leaves which cools the air around them. Compare the shade of a verandah to the shade of a big old tree and see which is cooler on a hot summer day!
Last week I made up some portable shade cloths to completely cover the veggie patch. I had a roll of white calico and stapled it to some long tomato stakes. In past years, I've draped old sheets over the plants but in hot northerly winds, they soon blow away. The idea still needs a bit of tweaking- some brackets to hold the stakes to the fence perhaps. They worked well on a hot day last week but I admit there was no wind that day. Nonetheless, the plants underneath did not wilt anywhere near as much as on days when the sun beats directly on them.

One more thing to keep in mind- think ahead. I have some seedling starts in pots and was going to plant some out today. Then I remembered tomorrows forecast is for 39oC. The heat along with the transplant shock would probably kill them. Keep an eye on the forecast and don't plan plantings during heatwaves! Common sense, perhaps but I've been caught out before!
Are you planning ahead for summer? What are you doing differently with this crazy climate of ours?
