Extremely high temperatures during a heatwave can place many plants under so much stress that they may or may not recover. The stress also leaves them vulnerable to plant diseases and pests.
When temperatures climb above 90 degrees for more than an hour or so, plants experience excessive water evaporation through the pores of the leaves faster than the roots can absorb water. The leaves of the plants wilt from the heat stress. Just like humans, plants can also become sunburned from extended exposure to direct sunlight. Plant sunburn appears as discolored leaves and stems and scorched edges.
We’ve put together 12 ways to protect your plants during a heatwave and help them recover. Don’t forget to keep yourself protected and hydrated, as well!
If Your Hydrangeas Are Drooping, the Summer Heat Isn't the Only Culprit Check The Soil Before WateringAlong with scorched and droopy leaves, the best way to tell if a plant needs water is to check the soil. Use a moisture meter or your finger to determine if the soil is dry two inches before the surface. If it is, it’s time to water. Container-grown plants need extra attention to determine a watering schedule. Depending on the size and type of container, twice-daily watering may be needed to keep plants healthy.
Water DeeplyIf you water for just a few minutes every day, plants will develop shallow roots that won’t stand up to extreme heat. It’s much better to water less often but water deeply so the soil is wet at least three inches deep. In general, gardens need around 1.5 inches of water weekly during heatwaves with little or no rain. That’s about one gallon of water per square foot of garden space.
38 Heat-Tolerant Container Garden Ideas For Sweltering Summers Water In TheChrysanthemums or mums are a must-have for autumn décor. They are perfect for pairing with pumpkins and gourds, and steal the spotlight with an explosion of blooms in fiery red, orange, and yellow hues that echo the autumn foliage. You’ll also find vibrant pink, lavender, and even white mums to dress up containers and gardens. Mums are easy to care for but require regular watering to keep them flowering for many weeks. How much water plants need and how often you should water mums varies depending on where the plant is growing. Follow these simple tips to determine when to water mums and keep them looking their best all season.
Green leaves are the energy engines that fuel our gardens. Without them there would be no flowers, no sugars for summer tomatoes, and no cooling or oxygenating the air while growing the mighty trees that give landscapes a sense of time and permanence. A gardener’s admiration of leaves can quickly fade, however, when faced with brown leaves blanketing everything from azaleas to annuals, and patios to pools. Leaves are suddenly a problem, something to manage—in other words, work.
Let's be honest: staying on top of cleaning and organizing every room in your home can get overwhelming—and before you know it, piles of junk on countertops and crammed-full kitchen cabinets can feel unmanageable.
