As temperatures rise, May is the time to fine-tune your landscape care routine to keep plants healthy while using water efficiently:
- Water trees deeply: Encourage strong root growth by watering less frequently but more thoroughly.
- Mulch for moisture: Apply organic mulch around citrus, roses, and perennials to help retain soil moisture and regulate temperature.
- Stay ahead of weeds: Remove fast-growing weeds early to prevent them from competing for water and nutrients.
- Watch for chlorosis: Yellowing leaves may indicate iron deficiency—treat with soil acidifiers as needed.
- Check your irrigation system: Inspect for leaks, overspray, or runoff to avoid water waste and ensure proper coverage.
