Timing and Frequency: Watering early in the morning or late in the afternoon reduces evaporation losses and allows plants to absorb moisture effectively. As plants mature and become more drought-resistant, gradually reduce the frequency of watering. Monitor soil moisture levels using a moisture meter or by simply checking the soil with your fingers to determine when watering is needed.
Mulching: Applying a layer of organic mulch (such as wood chips, straw, or bark) around plants helps retain soil moisture, suppress weeds, and regulate soil temperature. Mulch reduces the need for frequent watering and improves the overall health of the soil as it decomposes.
Pruning and Care of Plants
Regular pruning and care are vital for maintaining the health and appearance of your drought tolerant landscape. Here are some best practices:
Pruning for Health: Regularly prune dead or diseased branches to promote healthy growth and improve air circulation. This helps prevent pest infestations and diseases, which can be more prevalent in crowded or neglected plants. Prune flowering plants after they bloom to encourage new growth and additional blooms in the next season.
Fertilization: Drought tolerant plants generally require less fertilizer than traditional gardens. However, a light application of organic fertilizer during the growing season can enhance plant vigor and flowering. Choose slow-release options that provide nutrients over time without risking nutrient runoff into the environment.
Weed Management: Keeping weeds at bay is essential for maintaining a healthy landscape. Weeds compete for water and nutrients, which can negatively impact your drought tolerant plants. Regularly check for weeds and remove them by hand or use landscape fabric under mulch to suppress their growth.
Monitoring Plant Health: Regularly inspect your plants for signs of stress, disease, or pest infestations. Early detection allows for prompt intervention, which can prevent more significant problems down the road. Look for yellowing leaves, stunted growth, or unusual spots as indicators of potential issues.
