Hydrangeas are beautiful flowering plants that need a lot of water, especially in hot weather. But did you know that watering them at the wrong time can actually harm them? Many people think that drooping leaves mean the plant needs water immediately. But that’s not always true. Let’s understand the best way to care for your hydrangeas so they stay healthy and full of flowers.
Why Hydrangeas Droop in the Sun
It’s quite normal to see your hydrangeas drooping during a hot, sunny day. This doesn’t always mean they need water. According to gardening expert Stephanie Fleming, many gardeners rush to water them right away. But the president of the American Hydrangea Society suggests waiting until the next morning. If the plant is still drooping after a cool night, only then it truly needs water.
When Is the Best Time to Water Hydrangeas?
The best time to water hydrangeas is in the early morning when the weather is still cool. Watering during this time helps the roots absorb the moisture properly. If you water in the afternoon, the hot sun can heat up the water and cause the leaves to burn. This can make the plant more stressed and less able to produce energy.
What Happens If You Water Them in the Afternoon?
Watering your hydrangeas in the heat of the day can cause many problems. The water may evaporate before the roots can absorb it, which means the flowers won’t get enough water. Also, hot water on the leaves can burn them, making it harder for the plant to grow strong and healthy flowers.
How Often Should You Water Hydrangeas?
During hot weather, garden hydrangeas usually need to be watered about two to three times a week. But always check the soil first. If it feels moist, wait a few more days. For hydrangeas in pots, the soil dries out faster. You should check them daily and water them every day if needed.
Extra Tips for Healthy Hydrangeas
In late spring, hydrangeas need more water to support flower growth. Make sure they get enough water so they can bloom beautifully in summer. Avoid using fertilisers when the weather is too hot, as it can burn the roots. Instead, use mulch. Mulching helps keep the soil cool and moist. You can use materials like shredded bark, straw, hay, or wood chips. These slowly break down and give the plant nutrients to grow better flowers.
Caring for hydrangeas in the right way can make a big difference in how they look and grow. Always water them in the morning when it’s cooler. Don’t panic if they droop during the day—wait and check the next morning. Use mulch instead of fertiliser in hot weather, and keep an eye on how often the soil dries out, especially if they’re in pots. By following these simple tips, your hydrangeas will bloom beautifully and stay healthy even in the summer heat.
