Heat Protection
Painting the base of a young tree will also help it remain cool in the spring. Why? Because white paint acts as a shield that reflects the heat and allows the tree to spend more time on transpiration and growing their fruits.
Additionally, when trees are cooler, they have less stress, which makes their stomata stay open a bit longer for the exchange of gases. That’s extremely important because the more carbon dioxide the trees take in, the more energy they create.
