In this case due to frigid temperatures, some plants fold/curl their leaves reducing their surface area to prevent moisture loss through leaf stomata (leaf pores mostly on the underside of leaves) due to transpiration. Plants also practice thermotropism in response to heat. ☀️You may have seen tomato leaves curl up (leaf roll) on a hot or windy day. This defense mechanism help reduce/prevent water loss.💧 Have a great day and happy gardening!💚 📖 More gardening tips can be found in my upcoming book, “Four-Season Food Gardening.” Available to pre-order now and will be released in spring!
