Six Tips to Keep Plants Thriving During a Heat Wave

Tips to keep plants healthy, safe, and thriving during a heat wave.

With a heatwave gripping Rockland, Bergen County, and the Lower Hudson Valley, local gardens are feeling the strain of scorching summer temperatures. But with the right care, home gardeners can help their plants survive, and even thrive, despite the extreme heat. Down to Earth Garden Center in Pomona shares six essential tips to keep your garden healthy during these intense conditions.

  1. Water Wisely

During a heatwave, how and when you water your plants makes a big difference. Water your plants in the morning, giving plants time to absorb moisture before temperatures peak. Deep watering is a must so the moisture reaches the root, not just the surface. Skip evening watering, which can lead to fungal growth.

2. Mulch to Retain Moisture

Mulch is a simple but powerful tool during a heatwave. Adding a layer of organic mulch—like straw, wood chips, or shredded leaves—around your plants helps the soil retain moisture and keeps root systems cooler. It also cuts down on weeds, which compete with your plants for water.

3. Avoid Fertilizing

Hold off on fertilizing during a heatwave. Fertilizer can prompt new growth that demands more water, something already in short supply during extreme heat. Wait until temperatures drop before resuming your regular fertilizing routine.

4. Prune with Caution

Extreme heat is not the time for major pruning. Pruning can stress plants and expose sensitive areas to direct sun, increasing the risk of dehydration. If you need to prune, stick to removing only dead or damaged growth to help your plants conserve energy and moisture.

  1. Keep an Eye on Container Plants

Container plants are especially vulnerable during a heatwave. They tend to dry out faster than those in the ground, so check them twice a day and water as needed. If possible, move containers to a shaded area to reduce stress. Grouping them together can also help create a more humid microclimate that holds moisture longer.

  1. Monitor and Adjust

Pay close attention to your plants during a heat wave. Signs of stress like wilting, yellowing leaves, or dry, crispy edges mean it’s time to adjust your routine. Whether it’s more frequent watering, added shade, or moving containers, small changes can make a big difference in helping your garden weather the heat.

By following these simple strategies, you can give your plants the support they need to withstand the heat. With proper care, your garden can stay vibrant and healthy, even during the most intense summer days.
