Help Flowers Withstand the Heat

0

Heat waves are an inevitable part of summer in many places across the globe. While humans can escape indoors to air conditioned rooms when heat waves hit full swing, flowers planted around a property have no such luxury, putting their survival in jeopardy whenever the mercury rises to especially steamy heights.

Wilted flowers that have succumbed to the summer sun are a sight many gardening enthusiasts can recognize. But there are ways to keep flowers safe and vibrant during periods of extreme heat.

Water at the appropriate times of day. The National Gardening Association notes that it’s best to water in the early morning and evening because less water will be lost to evaporation during these times of day than during the afternoon, when temperatures tend to be at their hottest.

Choose the right watering method. It’s not just when but also how you water that can affect flowers during summer heat waves. Aboveground sprinklers might be great for lawns, but the NGA notes that such sprinklers can encourage the spread of disease on certain plants, including roses. Many gardening professionals recommend soaker hoses when watering flowers because they promote deep watering that can help the plants withstand the summer heat.

Routinely check the soil moisture. Soil moisture can help gardeners determine if their flowers have enough water to withstand the heat. The NGA advises gardeners to dig a 12-inch deep wedge of soil from their gardens to determine its moisture levels. If the top six inches of the soil is dry, water.

Avoid overwatering. Novice gardeners may be tempted to water more frequently when they see wilted leaves on their flowers. But wilted leaves are not necessarily indicative of suffering plants. Plants release moisture to protect themselves from excessive heat, and that release of moisture can cause leaves to wilt as the plants try to protect themselves by providing less surface area that can be exposed to the sun.

No gardener wants to see their flowers succumb to the summer heat. Fortunately, there are many ways to help flowers survive heat waves.
