Planting and Maintenance Strategies for Thriving Drought-Tolerant Ground Cover
Selecting the right drought-tolerant ground cover is only the first step towards a water-wise California garden. Proper planting and ongoing maintenance are critical to ensure these plants thrive and fulfill their intended purpose. This section provides practical guidance for establishing and maintaining your drought-tolerant ground cover, ensuring long-term success.
Soil Preparation: The Foundation for Growth
The key to successful drought-tolerant gardening lies in preparing the soil correctly from the outset. Many California soils, particularly in developed areas, can be compacted or lacking in essential nutrients.
Good drainage is paramount, especially for plants that dislike "wet feet." Amend heavy clay soils with plenty of organic matter, such as compost or well-rotted manure. This will improve drainage and aeration, creating a more hospitable environment for roots.
For sandy soils, organic matter will improve water retention and nutrient availability. Consider adding a layer of decomposed granite to further enhance drainage.
Testing your soil pH is also a wise move. Most drought-tolerant plants prefer a slightly acidic to neutral pH (around 6.0 to 7.0). You can purchase a simple soil test kit at most garden centers.
Watering Strategies: From Establishment to Maturity
While these plants are drought-tolerant, they still require adequate water, especially during the establishment phase.
After planting, water thoroughly to settle the soil around the roots. For the first few weeks, water regularly, ensuring the soil remains consistently moist but not waterlogged.
Once the plants are established (usually after a few months), gradually reduce the frequency of watering.
Observe your plants closely for signs of stress, such as wilting or yellowing leaves. Adjust your watering schedule accordingly, keeping in mind that regional microclimates can significantly influence water needs. Remember that overwatering can be just as detrimental as underwatering.
Mulching: Nature's Helping Hand
Mulching is an invaluable practice for any garden, but it's particularly beneficial for drought-tolerant landscapes.
A layer of mulch around your ground cover plants helps to conserve soil moisture by reducing evaporation. It also suppresses weed growth, minimizing competition for water and nutrients.
Organic mulches, such as wood chips or shredded bark, decompose over time, enriching the soil with organic matter. Inorganic mulches, like gravel or decomposed granite, are also effective for weed control and can add a decorative touch to your garden.
Apply a 2-3 inch layer of mulch around your plants, being careful to keep it away from the stems to prevent rot.
