Drought-tolerant shrubs that have a sunny position do not necessarily need to be spiky, thorny shrubs.
In areas with mild winters and hot, dry summers, there may be certain parts of your garden that are baking hot and sunny, with limited or no irrigation. These areas are ideal for shrubs that thrive in full sun and are drought tolerant.
This area may be close to a wall that reflects the heat, or close to paving, or your drive. Choosing the best shrubs for this growing condition is essential. Many shrubs embrace the heat and sun, with little water.
However, many people treat their drought-resistant plants like any other garden plant and water them regularly. Be aware that after they have established, they have adapted to very little water.
Drought In The USA
Parts of the US are no strangers to drought conditions and water restrictions. The longest drought in California lasted 376 weeks, beginning December in 2011 and ending in March 2019. Learn how drought is affecting your neighborhood.
Established Drought Resistant Plant
An established plant is one that has settled into its present planting spot and has grown its root system from its former pot life at the nursery.
Most water-wise shrubs have a tap root or a root system that extends very far in search of water.
Giving them regular watering for the first growing season is recommended. Plants in a garden bed should all require the same watering needs.
How Do You Landscape With Drought-Tolerant Plants?
Before planting, get rid of all weeds and rake the area to smooth. Good drainage is essential. Drought-tolerant shrubs do not like "wet feet."
Make sure to check the sunlight requirements beforehand.
Amend the soil by adding compost and prevent water run off from compacted dry soil. Whether your soil is clay or sandy, it will always benefit from additional compost.
Roughly sketch your design out on paper, keeping the bigger plants at the back of the bed in a layered effect with the medium height plants in the middle and the smaller plants in the foreground.
Use mulch or stepping stones or crushed stones in high traffic areas.
Organic mulch such as woodchips breakdown and improve the soil in time.
When using inorganic mulch such as crushed rock or small stones, place weed guard fabric under the rock mulch. The fabric will keep the soil and rock/stones from mixing as well as keeping weeds at bay for a few years.
Mulch keeps the soil cool and limits evaporation, as well as reducing run-off.
Mulching is the best way to suppress weeds, which will compete for the water.

When planning for a water-wise garden, consider the native shrubs from your area or plants which have these characteristics.
- small needle-like leaves, e.g., Rosemary
- grey foliage which reflects the sunlight, e.g., lavender
- hairy foliage, e.g., lambs ear
- succulents which store water in their fleshy leaves
- waxy leaves which prevent moisture loss, e.g., kalanchoe
One style of a xeriscape landscape is one that requires little or no irrigation for arid and semi-arid climates.
Another xeriscape garden is creating a regionally appropriate landscape that conserves water. Once established, a xeriscape garden requires very little maintenance.
Do not be put off from xeriscape gardening, thinking it is stones, rocks, and cacti and a few Yukka. A xeriscape garden can be as sparse or as lush as you like, as long as you stick to the main principle of using plants with the same water requirements.
