Apply organic mulch around plants to retain soil moisture and regulate temperature.

3. Opt for Native Perennials

Choose plants native to your region; they are naturally adapted to local climates.

4. Incorporate Hardscaping

Use stones, gravel, or pavers to reduce water usage while enhancing aesthetics.
