7 Drought-Tolerant Herbs for Southern California Gardens + Tips
Southern California seems to be in an almost perpetual state of drought, which means all of us must do our part to conserve water. Much of the water used in residential settings is used to irrigate landscaping, so this is a key aspect to consider when determining how best we can save water in our homes.
Of course, most exterior water usage at private homes goes towards watering natural grass lawns; therefore, the most important first step for anyone who still has natural grass is to reduce the size of their lawn or replace it with low-water alternatives. This, alone, will significantly reduce water waste and will help these homeowners save money on their water bills.
Aside from reducing or replacing natural grass lawns, homeowners can also reduce water waste by landscaping with native plants or non-natives that originate in similar climates and can thrive in Southern California with minimal irrigation and care. We can use drought-tolerant ornamental options for landscaping borders and flowerbeds, while also choosing low-water options for growing in our food gardens or herb gardens. We can also use a combination of both to create edible landscaping that adds texture and color to our outdoor living areas while also providing herbs for culinary or medicinal purposes.
For those of us who like to grow herbs for use in cooking, crafts, or home remedies, we can look to low-maintenance, drought-tolerant herbs to grow in containers, raised beds, or in the ground. It is most obvious to look to native herbs when selecting varieties for your garden, but there are also many herbs that are not native to Southern California but that are native to a similar client in Mediterranean countries. This means that we can add these herbs to our list of options that will thrive here with minimal water and care. Oregano and thyme are two good examples of herbs that are not native to Southern California but can be grown as natives here.

The drought-tolerant, low-growing ground cover varieties spread out across an area forming a mat and can be walked on. This makes them a good choice for growing in turfstones, around stepping stones in walkways, or bordering paving stone patios and paths.
If you are looking for a living ground cover, thyme might be a good choice, since it will give you the look you want without the excessive irrigation requirements of other living options.

Tips for Growing Drought-Tolerant Herbs
Here are five tips for helping your drought-tolerant herbs thrive in Southern California:
1. Install a Drip System.
Drip irrigation is the most efficient way to water plants without losing excessive water to wind or evaporation. It achieves this by delivering the water directly to the base of the plant. This will help you save even more water while making sure your plants receive the irrigation they need.
2. Water Early or Late in the Day.
To avoid evaporation and conserve water, it is best to water your food plants and landscaping either early in the morning or later in the evening. If you are using an automatic irrigation system, you can set it to water in the early hours of the morning. If you water by hand, do your watering soon after you get up or in the early or late evening.
3. Layer on the Mulch.
A good layer of mulch helps soil retain moisture, which will help your plants thrive with less irrigation. Mulch also helps maintain soil temperature and limit weed growth. As it breaks down, natural mulches will also add nutrients to the soil.
4. Remember that Growing in Containers is Different.
Plants growing in containers may need more or less water, depending on the type of container. Glazed pots hold water well, which generally calls for less frequent watering. Terra cotta pots and other unglazed planters generally dry out faster and may need a bit more water.
5. Amend Your Soil.
Drought-tolerant herbs generally prefer well-draining soil, which is pretty much the opposite of the clay soil found in much of the San Diego area and in Southern California. If your soil is particularly dense, you may need to amend it with compost or mulch to improve drainage.
