Here are some of the lessons I've learnt so far:
The xeriscaping process begins right at the planning stages of the garden.

I didn't take water-efficiency into consideration when planning my first garden in Phokeng and I paid the price through dying plants and heavily reduced harvests.
My challenge was that I had a big patch of land that had been neglected for over 10 years and the weeds were displacing us out of the yard. So I needed to do something and since I was already planning to grow our food, I decided to grow as much as I could.
I do have a designated garden which has structure. But there were also areas I needed to cover with something until I could properly plan for them time and resources allowing. The above patch is one of them.
After some of the vegetables I planted became crispy critters mid-season, I had two options: give up and do a lot of hard landcaping or try to work with the land and climate to get the results I want. I opted for the latter. Hopefully xeriscaping can help me do it.
Select a site that allows the efficient use of water

So for me it was not so much about selecting a suitable site, as it was about making the availabe site suitable for water-efficient gardening. It's a work in progress, with many issues I've yet to resolve.
Planting fruit trees allows me to meet several objectives at once: access to a consistent supply of free fruit and providing shade in my garden.
I am keeping in mind that many vegetable plants need 6-8 hours of sunlight. However, it doesn't have to be direct sunlight all the time, so while we already had a number of trees in that garden, they are not enough to offset the problem of extreme heat.
My challenge is making sure I don't plant too many trees and create too much shade. Then there is also the fact that fruit trees need water AND they will compete with the vegetables and herbs for water.
It's a conundrum. But I figure, if this solution doesn't work as advertised, the fenced vegetable garden will be designated as an orchard and I'll make the backyard space as my vegetable new vegetable garden (the space is bigger than the current garden and what you see in pic 1 around an 8th of the space, so I'd be OK with that)
In addition to the main fences, our whole yard is surrounded by trees which create a natural privacy wall. So the protection from strong winds is already in place.
Ensure that the soil has plenty of organic matter, such as manure, compost and mulch and that it is very well-drained.

That's just smart gardening, even when you don't have to deal with drought. But as I'm learning from gardening friends, mulching heavily and regularly is the key to retaining moisture in your garden.
Choose plants that are drought-resistant/can live for very long without water

This past summer, during which we went through a scorching summer with temperatures averaging late 30 degree Celsius (over 100 degrees Fahrenheit), the vegetables I mention above did well enough.
The watermelon and butternut leaves were drooped a lot, and some leaves were even burnt to a crisp, but they survived well enough.
|Look at my little basil fight to live|
|By the time the summer heat came, the greens were hardy|
As you can see, the plants themselves lived through the heat and they were a great source of greens, which we cooked in a similar style as we would cabbage leaves. They are now green afresh and ready to start fruiting again.
Position your plants strategically so that plants with the same watering needs are together.
I'm still learning on this one and have killed a number of plants in the process. But that's fine... I will keep trying.
Water your plants for maximum impact

For me, xeriscaping is a work in progress. So please share your water-efficient gardening tips so we can all benefit from your knowledge and experience.
