As temperatures soar, your garden plants may be feeling the heat.

Hot weather can stress plants, leading to dehydration if they’re not properly cared for. While watering is the obvious solution, timing and technique are key to keeping your plants healthy.

Watering your plants in the middle of the day, when the sun is at its peak, might do more harm than good.

At this time, the intense heat causes water to evaporate quickly, reducing the amount that actually reaches your plants' roots.

Additionally, water droplets on leaves can act like tiny magnifying glasses, potentially scorching the foliage.

Water During Cooler Hours

To make sure your plants get the most benefit, water them during the cooler parts of the day — either early in the morning or late in the evening.

The ideal time slots are between 6:00 and 9:00 AM or between 6:00 and 10:00 PM.

During these hours, the sun is less intense, allowing water to soak into the soil and reach the roots without evaporating too quickly.

As the temperature rises, your plants will need more water than usual.

Daily watering might be necessary, but it's important to check the soil first.

If it’s still moist, you can skip watering to avoid over-saturating the soil, which can lead to root rot.

In extreme heat, some plants may benefit from a bit of shade.

If they typically receive full sun and start to look wilted or stressed, consider moving them to a shaded area or using a parasol to give them a break from the direct sunlight.
