How to Protect Your Plants During Heatwaves

During a heatwave, plants lose significantly more water than usual due to accelerated transpiration. If the soil or substrate cannot provide enough moisture, the plant quickly becomes dehydrated. This can lead to wilting, flower and fruit drop, or even the death of young plants.

In addition, prolonged exposure to the sun can cause burns on leaves and stems, weakening their natural defenses against pests and diseases. That’s why during these extreme events it’s essential to implement protection measures: strategic watering, effective shading, and monitoring the plant’s condition.

Strategic watering with up to 60 days of autonomy CitySens vertical planters with digital or WiFi self-watering systems are ideal for heatwaves. They maintain optimal moisture levels in the substrate for weeks, reducing evaporation and eliminating the need for constant manual watering.

Programmable drip irrigation for indoor or outdoor plants Our drip irrigation kits with reservoir and timer allow you to set ideal watering times (at dawn or dusk) and save up to 50% water. An efficient and sustainable way to keep your plants hydrated during the hottest days.

Sun protection and urban microclimates Modular plant shelves allow you to organize your pots at different levels, creating shaded areas and cooler microclimates. You can also add shade cloths or light diffusers that protect from the sun without reducing brightness. All our structures are made from recycled materials that don’t overheat, protecting roots from thermal stress.

Heat-resistant plants and suitable substrates At CitySens we offer growing kits with Mediterranean plants such as lavender, thyme, or rosemary, specially adapted to warm climates. We also provide mixes of organic substrate and slow-release compost that retain moisture and reduce salt stress, which is key during heat peaks.

Efficient installation practices Avoid harsh interventions (like transplants or pruning) during the hottest days. Instead, use our modular structures that can be easily repositioned according to sun exposure. Group pots together to better retain moisture and add mulching or fibers to the surface of the substrate to retain water and lower soil temperature.

Conclusion Heatwaves don’t have to be a threat to your garden or indoor plants. With a preventive approach and the right solutions—such as self-watering planters, smart irrigation kits, modular shelves, sensors, and sustainable substrates—you can keep your plants green, healthy, and protected even on the hottest summer days.
