In the height of summer, with the sun shining brightly, you might expect the garden to be bursting with vigor. Yet, as you have probably noticed, in July and August, the growth of many trees, shrubs, and plants seems completely frozen. Young shoots stop growing, and buds lock up. <\/p>\n\n

Don’t panic! Your garden is not dying: it is simply taking its summer nap<\/strong>. <\/p>\n\n

Let’s take a look behind the scenes at what is happening in nature’s great laboratory.<\/p>\n\n

Estivation: The Survival Strategy Against Heat<\/h2>\n\n

Everyone knows about hibernation, the deep sleep that certain animals and plants share to get through the winter frost. But did you know there is a summer equivalent? This is called estivation, or summer dormancy. <\/p>\n\n

For a plant, growing requires colossal energy and, above all, an astronomical amount of water. When the thermometer rises and rainfall becomes scarce, the tree must make a choice: continue to grow at the risk of dehydrating, or shut down the machinery to preserve its life. The choice is easily made. <\/p>\n\n

The Secret Mechanism of Stomata<\/h3>\n\n

Under the leaves of your plants lie thousands of microscopic pores called stomata<\/strong>. Normally, they open to breathe and absorb carbon. However, by opening, they allow water to escape (this is transpiration). <\/p>\n\n

During the intense heat of August, to avoid emptying themselves of water, plants seal their stomata. The direct consequence: sap circulation slows down, photosynthesis runs in slow motion, and growth stops. The plant enters ‘energy-saving’ mode. <\/p>\n\n

Why This Break Is Excellent News for Your Plants<\/h2>\n\n

This visual stagnation sometimes worries gardeners, but it is actually vital. If a tree continued to produce tender, water-gorged young shoots in the middle of August, they would be instantly scorched by the sun or dried out by the hot wind. <\/p>\n\n

By blocking its growth, the plant takes the opportunity to accomplish invisible but crucial work:<\/p>\n\n
