Heat Can Be Good or Bad for Your Garden 2024-07-30 Summer brings very high temperatures to many parts of the United States. That can be both good news and bad news for gardens and gardeners. Jessica Damiano writes about gardening for the Associated Press. She keeps a garden in New York, where summer temperatures can reach 32 degrees Celsius. Recently, Damiano repeated a difficult truth for gardeners: weather has a lot to do with success, but it is out of our control. There are measures that plant lovers can take to ease the effects of hot summer weather. One measure is to spread a thick layer of mulch over plant roots. This can help keep plant roots cool and will preserve water, or moisture, in the soil. When watering plants, use a lot of water and let it soak deep into the ground. You can water your garden less often if you provide a few deep soaks regularly. Light watering causes roots to spread near the surface of the soil. If there is too much sun for young plants, don't be afraid to give them shade. Damiano said she has been known to place an umbrella on the ground to protect tender plants from the sun. The good news about heat Heat is not all bad for a garden. Some plants love heat. Damiano grows a kind of tomato called Big Boy. The plant, she says, has grown quickly in the summer heat. Zucchini, a form of squash, also does well. Heat can also keep harmful insects away. Cabbage, onion and corn maggots prefer cooler weather and struggle in the heat. So do cutworms, which can be especially destructive to gardens. Damiano says some of her perennial flowering plants have bloomed two weeks earlier than usual. For this reason, she decided to add late-blooming plants to her garden to ensure a good crop of flowers. She reported that her hydrangea plants have never looked better. She has 12 of them, and they are blooming well. However, Damiano said that might not be the result of hot weather this summer. Instead, unusually heavy rains late last summer and fall may have helped buds to form. A smaller number of those buds were damaged by the mild winter weather. The result is a lot of blooms. And the downside Some plants suffer in the heat, including impatiens. The small flowers are not doing well. But what Damiano dislikes are the creatures that become more active and numerous when temperatures rise. Mosquitos are most active at sunrise and sunset, but they can bite at any time. Although heat theoretically slows their activity, hot conditions can help mosquitoes spread. Damiano advises to prevent water from collecting in places around the garden or to put something called Bti in wet areas where mosquitos might lay eggs. Bti is a kind of bacteria that produces a substance poisonous to young mosquitos and a few other flying insects. It is natural, and the U.S. Environmental Protection Agency (EPA) says it is safe for people and most other insects and animals as well. Ticks present another problem. The creatures bite people and spread disease. Cold weather kills them, but they do well in hot weather. Normally found in the eastern U.S. and on the Pacific coast, ticks appear to be spreading to new areas. The EPA even said, "Climate change has contributed to the expanded range of ticks." Wearing long sleeves and pants and using special chemicals to keep ticks away can help protect against their bites. Earwigs also like heat and humidity. They can make holes in plant leaves, Damiano said. But the "pincher bugs" also eat aphids, which are enemies of the garden. So are thrips and spider mites. In addition to insects, heat and humidity are good conditions for slugs. These creatures have soft slimy bodies, and they eat plants. Luckily, there are easy ways to control these garden problems. One is to spray soapy water onto soft-bodied insects like aphids, spider mites, thrips and whiteflies. As for slugs, salt will kill them but is not good for garden soil. They do not like sharp surfaces, however, so adding crushed eggshells can be an effective control method. The eggshells break down and nourish the plants over time.
