3. Group Plants by Water Needs
- Create zones for plants with similar water requirements to optimize irrigation.
4. Use Rock Landscaping
- Add decorative rocks or gravel to reduce evaporation and highlight drought-resistant plants.
Tips for Caring for Plants in Hot or Dry Regions
1. Water Deeply and Infrequently
- Watering deeply encourages plants to develop deep root systems.
2. Choose the Right Soil
- Use sandy or well-draining soil to prevent waterlogging.
3. Shade Young Plants
- Provide temporary shade for young or newly transplanted plants during extreme heat.
4. Prune Regularly
- Remove dead or damaged foliage to focus the plant’s energy on healthy growth.
5. Monitor for Pests
