Watering Strategies for Drought-Tolerant Ground Covers
When it comes to watering drought-tolerant ground covers, efficiency is key. To avoid overwatering and promote deep root development, follow these strategies:
Overwatering can be detrimental to even the most drought-tolerant plants, so it’s essential to water them only when necessary. Check the soil moisture by inserting your finger into the soil up to the knuckle. If the soil feels dry, it’s time to water. Water thoroughly but infrequently, allowing the top 2-3 inches of soil to dry out between waterings.
Another important tip is to water in the morning or early afternoon when the sun is not intense. This allows the plants to absorb the water throughout the day and reduces evaporation. Additionally, avoid watering during peak heat hours (usually between 11 am and 3 pm) as this can cause more water loss due to transpiration.
To promote deep root development, use a soaker hose or drip irrigation system which delivers water directly to the roots. This method encourages plants to develop deeper roots, making them more resilient to drought conditions.
