Heat waves can be devastating for outdoor plant boxes, causing dehydration, wilting, and even plant death. To protect your plants, follow these steps to create an effective heat wave protection plan:

1. Choose Heat-Resistant Plants: Opt for drought-tolerant species like succulents, lavender, or rosemary that thrive in hot conditions.

2. Provide Shade: Use shade cloths, umbrellas, or taller plants to shield delicate greens from direct sunlight during peak hours.

3. Mulch the Soil: Apply a thick layer of mulch to retain moisture and regulate soil temperature.

4. Water Smartly: Water plants early in the morning or late in the evening to minimize evaporation. Drip irrigation systems are ideal.

5. Monitor Soil Moisture: Use a moisture meter to ensure plants aren’t over or under-watered.

6. Use Reflective Materials: Place light-colored stones or reflective mulch to deflect excess heat.

7. Group Plants Strategically: Cluster plants together to create a microclimate that retains humidity.

By implementing these measures, your outdoor plant boxes can survive and even thrive during extreme heat waves. Stay proactive and adjust your plan as temperatures rise!
