How to Protect Your Garden from Heat Stress

Beating the Heat: Protect Your Plants From Heat Stress

Hot weather can be hard on your plants. Just like us, they need special care in extreme heat. Even with adequate watering and mulching, plants can suffer when the temperatures rise but there are a few things you can do to help protect your plants from heat stress during the hottest part of the summer.How to Protect Your Summer Garden from Heat Stress

Water Correctly
Watering is essential when it’s hot, but watering correctly is far more important. Watering in the morning or early evening is the best for your garden. Giving them water midday is inefficient and most of it will evaporate before it gets to the roots. Strive for a deep watering two or three times a week. Using a drip irrigation system or a soaker hose will ensure a deep watering, but if you do not have an irrigation system, an overhead sprinkler or hand watering will work, just do it in the cool hours of morning or early evening.Protecting Plants from Heat Stress by using proper watering techniques

Over Watering

Too much water can cause damage to your plants as much as under watering can. Heat and sun exposure will cause leaf wilt, occurring because of transpiration, or when plant releases moisture to protect itself in excessive heat. The leaves are wilting so there is less surface area for the sun exposure. “But,” you say, “they look so thirsty!?” Resist the temptation to water and feel the soil for moisture. Over watering can lead to root rot or fungal diseases (when a plant is continuously over watered, it can deprive the roots of oxygen and promote the growth of fungi in the soil). Don’t worry, your plants will bounce back when the sun goes down.

A thick layer of mulch helps insulate the plant’s roots from both heat and cold. It will also help keep the soil moist. If your garden is prone to extreme temperatures, strive for at least 4-6 inches of mulch in your garden. Straw, pine needles, leaves, and grass clippings make good, inexpensive mulch. Lay it on thick; your plants will love you for it.

During extreme heat, plants will cease flowering and can get sunburned. When temperatures get into the mid 90’s Fahrenheit, plants like peppers, tomatoes, and eggplants hold back flowering. A good way to remedy this is to give them some shade during the hottest part of the day. You can use a patio umbrella for a small area or a lightweight piece of fabric (like a flat bed sheet) stretched over a trellis to shade sections of your garden.

Choose Heat-Tolerant Plants

There are many plants out there that love the sun and thrive in the intense heat of summer’s peak. For more information and a list of plants that will stay happy and vibrant throughout summer, wait a few days and we will be posting an in-depth list of the best heat-tolerant plants.

Take Care of Yourself
Most importantly, make sure you are taking the right safety precautions when out gardening in the heat. Skip the hottest part of the day when doing garden chores and instead head out to the garden in the morning and evening. Work in shorter increments and take regular breaks. Gardening in the summer is a much slower pace; listen to your body if you need to step out in the heat. Apply sunscreen, sun protection lip balm, and wear a hat. Like your plants, be sure to stay hydrated. Sweating will help cool your body down, but you need to keep your body replenished. Water is best for hydration, but you can also quench your thirst with a cool glass of sun tea or lavender lemonade!Lavender soda recipe - made with beautiful homemade simple syrup

Taking a few precautions this summer will help you and your garden stay healthy and cool during the most extreme heat. Cooler days will be here before you know it, so enjoy the warm weather while it lasts.

    This was very good information! And it was right on the very things I was struggling with. I had experienced gardeners telling me to water my plants more, and yet they would die quicker when I did. Funnily enough, before I would water, I put my finger in and encountered water at about a depth of 1 1/4 to 1 1/2 inches. I wondered if they were being overwatered.

    Hey! This is a really great post. I love that you added a section on not overwatering! It’s so easy to fall into that trap if you don’t know to avoid it. Mulching is also so underrated by new gardeners, but it protects the plants so well from both heat and cold! Thank you for writing this. I wrote a similar post on my own blog that also talked about mulching and shade to keep plants cool, as well as some tips for protecting them from cold and sudden shifts in temperature in general. One thing I do with my own container plants is cover them with small gravel, like the kind you can find for fish tanks. It looks nicer than ordinary mulch for indoor plants, and it insulates them almost as well. It keeps the moisture in anyway!
